In the figure (32b), the screw 1 is fixed to the other end of the upper surface of the printed circuit board with a spacer inserted through the upper surface of the mounting frame I and screwed into the spacer 0. When the frame 43 and the handle 27 are assembled, the inclined liars (27a) (27a) on the lower surface of the handle 27 are small switches, respectively. 52a) (52a)' as shown in FIG.

FIGS. 6(a) and 6(b) show a top view and a side view of the embedded switch of the present invention, which has been assembled as described above. 69) in the figure is the mounting provided on the mounting frame (c), 6
I is a mounting hole, and these holes 1591131 are for use when the mounting frame is fully recessed, or when mounting on a wall surface, etc. Figure 7 shows a mounting hole on a printed circuit board, circuit,
That is, it is a circuit diagram showing a dimming/extinguishing circuit of the lighting load (8). Next, the configuration and operation of this circuit will be explained based on a circuit diagram. In the figure, (1) is an on-operation detection circuit for detecting the operation of the operation switch SW. ) A phase control element such as a triac 1mm mushroom provided in the load control circuit (2) is set to a fully conductive state by making a meeting wJ. First delay circuit (8
) is set after the operation switch SW is turned off ν) Sets the triac TI to be fully conductive and maintains the full lighting state of the lighting load (3) for a certain period of time even after the operation switch SW is turned off. It is for. When the delay output of the delay circuit (8) disappears, the switching circuit (7)
The full conduction setting of the triac T2 is switched to phase control. The second delay circuit (9) operates the dimming control circuit (10) at the time of switching to the phase control, controls the triac T of the load control circuit (2) to a predetermined phase angle, and controls the lighting load ( 3) to a predetermined level of brightness and to operate the dimming side overturning circuit 110) for a predetermined period from this point. #
, the optical control circuit j+01 gradually increases Teruo's negative VTf from the predetermined bell during the period in which the delayed output of the delay circuit (9) exists.
This is to give a trigger signal that gradually changes the conduction phase angle of the triac '[, of the load control circuit (2) in order to reduce the brightness of the triac 3).When the delayed output disappears,
This is done by stopping the output of the trigger signal to the triac Tl. The rectifier circuit (6) is a delay circuit (g) (9)
, the switching circuit (7), and the dimming control circuit (10).
It is constructed from D B 2.

However, when the operation switch SW is turned on now, a gate current flows to the gate of Y.
+ turns on. By this turning on, the power source (2) is connected to the lighting load (3) and all lights are turned on, and the current transformer CT
A current flows through the primary coil L1 of the secondary coil LtK, and an AC voltage is induced in the secondary coil LtK.
It is full-wave rectified by I and charges the capacitor 01.

On the other hand, the gate voltage of the field effect transistor FET reaches the Zener voltage of the Zener diode ZDI. Therefore, the field effect transistor FET is cut off, and as a result, transistor Q is turned on and transistor Q
4 is also a resistor, and the resistor that charges the capacitor 06 via the diode ridge DB2 is, for example, IOKΩ.
It consists of a parallel circuit consisting of a small resistor R1 with a resistance value of 200Ω, a series circuit with a large resistor R1 with a resistance value of 200 Ω, and a series circuit with a resistor R++ whose resistance value is compared to the resistance value R−K.
The time required for the voltage across the capacitor C6 to reach the breakover voltage to the triac D is extremely short, and as a result, the generation phase of the triac signal becomes near zero phase, making the triac T almost fully conductive. lighting load (3
) remain fully lit.

Next, when the operation switch sw is turned off, the capacitor Ct
The charge charged in VC is transferred to resistor R5 and 5T resistor VR.
The discharge is started through the field effect trough 5 star FET.
As the gate voltage of Q gradually approaches zero, the drain current of the field effect transistor FET gradually increases, and in response to this increase in train current, the voltage of the transistor Q gradually increases.・The voltage between the bases increases,
The base current begins to flow. This causes the collector current of transistor Q1 to flow, and in response, transistor Q! The base current:i flows and the collector current of the transistor Qs% flows. and field effect transistor FE
The gate voltage of transistor Q1.T will further approach zero, and as a result, transistor Q1. Q2 turns on, the field effect transistor FET turns on, and the transistor Q3 turns on.
When the transistor Q4 is turned off, the base current l-i of the transistor Q4 is supplied by discharging the charge of the resistor C4, and during the supply period, the transistor Q4
continues to conduct, and as the voltage across the capacitor C4 falls, the base current decreases and its impedance changes. Therefore, when the above-mentioned transistor Q is off, the resistor for charging the capacitor C6 is composed of a series circuit of a resistor R and a resistor R1t, and the voltage across the capacitor C4 is
Increase the time it takes for A to reach the breakover voltage.

Therefore, by setting the resistance values of R1 and Rh appropriately in advance, the conduction phase angle can be reduced by, for example, 50 inches.
iL:, 1. ,．． At the same time, the brightness of the lighting load (3) can be lowered by 50 degrees to notify the user that the light is about to turn off. Next, as the voltage across the capacitor C4 drops as the capacitor C4 discharges, the impedance of the transistor Q4 increases as described above. The time from after tS until the next tie-up DA reaches the leak over voltage gradually becomes longer.
The phase of the timing to force the C triac 'F word is delayed, and the triac T! As the conduction period becomes shorter, the brightness of the lighting load (3) gradually decreases.0 And when the voltage across capacitor C4 reaches a voltage at which transistor Q4 can no longer maintain conduction, the diode springs! ;DB2
The charging circuit that charges the capacitor cs through the triac T! It leads to the off. As a result, the lighting load (
3) is turned off. The change in voltage across the lighting load (3) from turning off the operation switch SW to turning off the light changes as shown in Figure 8.
1+ indicates the time when W is on, and 1+ indicates the time when W is off.

In this way, in the wc7 diagram circuit, the operation switch of the lighting load (3), the lighting time t after the switch is turned off is determined by the capacitor C.
3, the time constant of the variable resistor VR and the resistor Rs, and the time to of the dimming process up to +14 lights is set by the time constant of the capacitor C4 and the resistor R11.
In the embodiment, the former time is about 30 seconds to about 5 minutes, and the latter time is about a constant time of 15 seconds to 30 seconds.

Note that the operation switch SW may be inserted at the position of the triac Ts, and in this case, the triac T1 and the resistors R1 and Rs of the ignition circuit are unnecessary. In the figure, NE is a neon tube for energization indication, ZNR is a surge breaker, and A is a slave device connected in parallel to the operation switch SW, and this slave device has a neon tube NE for energization indication and an operation switch SWL. have L is a choke coil. Furthermore, the operation switch S
W is formed from two small switch blocks 1,
Of course, 41 switches are also acceptable.

In the dimming control circuit (9) of the above embodiment, the transistor Q
By using the current amplification function of 4 to gradually increase the impedance, TRIAC T! Although the conduction phase angle of the oscillator circuit is changed in this embodiment, a phase control pulse may be generated for each predetermined pulse by a combination of oscillation circuits. Furthermore, in the delay circuit +81 +91, capacitors C1 and C
Although the discharge time of m is used, a method of detecting time by counting prescribed pulses using a combination of oscillation circuits may also be used. Furthermore, although the on-operation detection circuit fi+ of the operation switch SW uses a current transformer CT, it is also possible to detect the on-operation of the operation switch SW by using an element such as a photocoupler. In the example, the brightness level of the lighting load at the start of dimming is approximately 50% higher than the brightness level when all lights are on before that.
-Although the brightness level is switched to decrease, phase control may be performed to gradually decrease the brightness level from the start of dimming.

In this case, if you dim the light for a relatively long time, it will automatically turn off when you go to bed, and can be used as a sleep switch.

As an applied modification of the present invention, if the phase of the triac, which is a phase control element, is controlled so that the brightness of the lighting load is gradually increased at the same time as the operation switch is turned on, it can be used in places where many people sleep in one place. When turning on a lighting load, it can also be used as a switch that does not disturb the sleep of those who do not need it.

Next, as shown in FIG. 9, which explains the case where the embedded switch according to the present invention is mounted on a wall surface W, wiring is performed in advance, and the inside of the mounting frame is fixed to the embedded pocket X or the wall surface W by screwing. Next, a decorative material Y such as D-su is attached to the wall surface W, and the decorative material Y is cut along the mounting frame A to expose the recessed switch according to the present invention. After setting and loosening the screws, attach the synthetic resin lower frame 14 to the lower surface of the mounting frame. In this case, first, loosely fit the screw 1DK into the notch in the lower frame shown in Figure 10, pass it all the way through the opening threshold in the center of the lower frame, and place the mounting frame (C) on top of the lower frame. position. Therefore, the lower frame 12) can be mounted on the lower surface of the mounting frame without removing the mounting frame (c). Then, place the mounting frame 1231 on the lower frame, fit the hole in the mounting frame to the protrusion on the lower frame, and tighten the screw v3at. Therefore, even if the decorative material Y is thick, the screw By tightening at 111, the entire decorative material Y that is in contact with the lower frame rod is pressed against the wall surface W side.

Next, after screwing the decorative plate Bη, which is a synthetic resin molded product, into the mounting frame together with the inner frame made of aluminum Thai beef yast, the decorative handle holder is loosely fitted into the opening of the inner frame G~, and the decorative handle is connected. The cylindrical edge of the handle (goods) has a concave chamber (2
7b), the locking parts -η on both sides of the cylindrical lip 4 engage with the locking claws on both sides of the fixed spring egg, and the makeup hand l
b 31 is in conjunction with Hasidor's love. At this time, the steady rest ridges Q at both ends of the cylindrical ridge 4 are also aligned with the grooves (27c) at both ends of the handle I271.

Before covering the brush, the makeup handle has a long hole (3)
6a) i is fitted and fixed. FIG. 11 is an exploded perspective view showing the relationship of the makeup brush 27).

The present invention provides a printed circuit board fully equipped with an electronic circuit that allows the load to continue for a certain period of time after the operation switch is turned off, and terminals such as load terminals, slave terminals, common terminals, etc. Attach the electronic circuit inside the container, fix the container to a metal mounting frame, and cover a part of the opening of the container with the mounting frame to prevent the electronic circuit stored in the container from falling over on the load side. Since the switch element is placed in contact with the mounting frame, the heat dissipation plate of the switch element can also be used as the mounting frame, which eliminates the need for space for heat dissipation, making the device more compact, and reducing the number of parts. It has the effect of reducing the number of points and reducing costs, and in the second case, the operation switch is a small switch such as a microswitch placed on a printed circuit board, and one end is fixed. The lower part of the center is supported by the plate-like struts, and the left side

Since the cap is covered with S-, the connection between the terminal and the external electric wire can be easily made using the connecting terminal, and it is also effective when it can be done with the insulating T'in cover between the terminal and the circuit inside the body. In addition, the electronic [L] J mounted on the printed circuit board is installed on the hand 1 of the control 1'F switch exposed from the opening of the mounting frame, and the makeup handle 1 is installed on the attachment/detachment point. The operating shaft of the variable resistor for variable time constant of the circuit is attached to the mounting frame K and F.
If the handle is connected to the back side of the cosmetic handle via
