BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power switch for various equipments installed in powder rooms (toilet rooms), toilet rooms, kitchens, bathrooms, etc., that is, household equipment. The power switch is a switch for turning on and off a load operated at AC100V or AC200V.

[0002]

2. Description of the Related Art Household equipment includes a vanity in a powder room, a shower / toilet in a toilet room, and the like, and a water heater and a remote controller for the water heater.

Conventionally, inexpensive rocker-type switches have been generally used as power switches for these devices. However, the rocker type switch has a difficulty in waterproofing.
Switches for residential equipment must be considered for operation with wet hands (fingers).

Therefore, a touch switch unit having a structure in which a waterproof sheet is covered on a momentary operation type push button switch has been devised. The touch switch unit
As shown in FIG. 1, it is composed of a switch section 9 and a switch circuit section 19, and constitutes a switch unit.

For example, a lighting switch and an anti-fog switch for a vanity are a momentary operation type push button switch (11a, 11) with an emboss 10 as shown in FIG.
b) has been often used, and in this case, as the load, a fluorescent lamp and a heater are applicable, respectively.

The switch section 9 is provided with a momentary operation type push button switch (11a, 11b) embedded in the flat plate member 4 below (inside) the waterproof sheet 3 so that water does not enter the inside of the switch. Push button 2
When is pressed, momentary operation type push button switch (1
The contacts (not shown) provided in 1a, 11b) are closed, and when the finger is released from the push button 2, the contacts are opened. The LED (light emitting diode) 14
Is a momentary operation type push button switch (11a,
11b) is provided to indicate the operating state.

The conventional touch switch unit for housing equipment is provided with a switch circuit section 19 in addition to the switch section 9, and the switch section 9 and the switch circuit section 19 are
It is electrically connected by a cable (electric wire) 13, and the AC power supply 15 is turned on and off in the switch circuit section 19 based on the contact opening / closing signal from the momentary operation type push button switches (11a, 11b).

Specifically, the open / closed state of the contacts of the momentary operation type push button switches (11a, 11b) is stored in a memory circuit (element) 7 such as a flip-flop IC, and based on a signal from the memory circuit 7, In the power semiconductor element circuit 8 equipped with a triac, etc.
I was controlling N / OFF.

A conventional touch switch unit for housing equipment is a momentary operation type push button switch (1
1a, 11b) storage circuit 7 for storing the input state and AC
Since a power semiconductor element circuit 8 such as a triac circuit for controlling ON / OFF of the power supply 15 is required separately from the switch unit 9, the size of the entire switch unit including the switch unit 9 and the switch circuit unit 19 is reduced. It was big. Further, it is very difficult to further reduce the cost of parts required for the switch circuit section 19.

This is because, in addition to the need for the memory circuit 7 and the power semiconductor element circuit 8 as described above, there are the following circumstances. For the memory circuit 7, it is general to use a flip-flop IC, which is advantageous in terms of cost, but since the normal IC operates at DC5V,
It is necessary to perform voltage conversion (step down) of AC100V (or 200V) with a transformer and rectify it. For this reason, the switch circuit unit 19 tends to be large due to the transformer 5 and the rectifier circuit 6, and the component cost of the switch circuit unit 19 cannot be reduced. Consequently, it is difficult to further reduce the manufacturing cost. Was there.

Further, since the conventional power switch (touch switch unit) for housing equipment is a touch switch operated by touching a seat, the operation feeling is not good, that is, it is clear whether or not an input is made. There was also the drawback of not doing it.

[0012]
