Description

[Detailed description of the invention] This invention relates to a manually operated switch used in control circuits such as electromagnetic switches and electromagnetic relays. For example, when the operation button is pressed, the switch part opens and closes and locks. This invention relates to an improvement in a switch that performs push and turn operations such that when the switch is twisted by a predetermined angle, the lock state is released and the switch returns to its original state.

Conventionally, this type of device has been a push-lock/turn reset operation switch as shown in FIGS. 1-5. In these figures, Fig. 1 shows the front, Fig. 2 shows the back, and Fig. 3 shows the − of Fig. 1.

4 is fixed to the operating body 15 by screws 16, and is provided so as to be slidable and twistable on the head case 5. The operating body 15 also has an intermediate member 15a in the center that comes into contact with the head case 5 and serves as a stopper, and a protrusion 15b for locking on the intermediate shaft 11 side, with a part of the protrusion 15b cut out. A reset recess 15c is provided. Reference numeral 17 denotes a fixed body that covers the convex portion 15b and concave portion 15c of the operating body 15, and this fixed body 17
A pair of through holes 17a are provided from the outer periphery toward the center, and a lock pin 18 that comes into contact with the operating body 15 and a lock spring 19 that biases the lock pin 18 toward the center are provided in the through holes 17a. When the operating body 15 moves in the direction of the switch portion 3 by a predetermined stroke 1, the lock pin 18 is engaged with the convex portion 15b. Furthermore, the operating body 1
The engagement sliding portion between the intermediate member 15a of No. 5 and the head case 5 includes a stopper portion 5a on the head case 5.
However, a protrusion 15d is formed on the intermediate member 15a, and when the intermediate member 15a rotates by a predetermined twisting angle θ, the protrusion 15d comes into contact with the stopper portion 5a and is configured to stop twisting. (See Figure 4). Reference numeral 20 denotes a reset spring provided for returning the operation button 14, one end of which is connected to the intermediate member 15a of the operation body 15, and the other end of which is connected to the fixed body 17.
It is locked to.

Next, the operation will be explained. When the operating button 14 is pushed, the operating body 15 connected to the operating button 14 moves in the direction of the switch portion 3 against the biasing force of the reset spring 20. When the operating body 15 moves by a predetermined stroke l, the convex portion 15b of the operating body 15
, the lock pin 18 is biased by the lock spring 19.
is engaged, and even if the push operation of the operation button 14 is stopped, the operation body 15 is locked at this position.
At this time, the operating body 15 pushes the crossbar 13 via the intermediate shaft 11 and the push plate 10 to open and close the switch portion 3. Next, the operation button 14 is rotated, for example, in the clockwise direction (the arrow shown in FIG. 1).
When the operating body 15 is rotated (in the direction of RESET),
rotates while biasing the reset spring 20 in the retracting direction, and when a predetermined twist angle θ is reached, the operating body 1
5 and the lock pin 18 are aligned, the locked state is released, and the operating body 15 is twisted back by the restoring force of the reset spring 20, and the pressure on the cross bar 13 is released and reset.

In the push-lock/turn-reset operation switch configured as described above, the only state change during operation on the front surface of the mounting panel 6 is whether or not the operation button 14 is pressed in, making it difficult to confirm from the front or from a distance. . In particular, this switch is often used for emergency stops and test circuits, and is required to be able to easily confirm its operating status.

In order to check the operating status as described above, it is possible to install an indicator light separately from the switch mechanism and check the operating status by blinking the indicator light, but this would increase the installation area of the switch and also reduce the number of partial points. This is undesirable as it increases the installation work and makes the installation work complicated.

This invention was made in order to eliminate the above-mentioned drawbacks of the conventional switch, and by forming a hollow part near the operation button of the switch and providing an illuminated display means in the hollow part, it is compact and the switch can be opened and closed. It is an object of the present invention to provide a push-lock/turn reset operation switch whose status can be easily checked.

An embodiment of this invention will be described below with reference to FIGS. 6 to 11. In the figures, Fig. 6 shows the front, Fig. 7 shows the back, Fig. 8 shows the cross section taken along the - line in Fig. 6, and Fig. 9 shows the operating body 1 in Fig.

It is composed of an operating mechanism section 4 and an illuminated display section 21.

The head part 1 consists of a head case 5 for housing an operating mechanism part 4, a tightening ring 7 and an adjustment packing 8 for fixing the entire switch to a mounting panel 6.

The switch part 3 is similar to conventional devices. The illumination display part 21 is configured such that an illumination display member, for example, a light bulb 22, is screwed into a socket 23 and connected to a terminal part of the switch part 3 through a power supply line 24, so that it blinks in conjunction with the operation of the switch part 3. has been done.

The operating mechanism part 4 forms a hollow part in which the illuminated display part 21 is housed, and the opening/closing operation of the switch part 3 is locked by a push operation, and the locked state is released by a twisting operation. In this operating mechanism part 4, the operating button 14 is made of a translucent material in order to easily check whether the light bulb 22 is blinking, and when the light bulb 22 is replaced. , is screwed and fixed to the operating body 15 so that it can be easily attached and detached, and is also provided so as to be slidable with respect to the head case 5. Note that the operation button 14 and the operation body 15 are hollow in order to accommodate an illuminated display portion 21 such as a light bulb 22. As shown in FIGS. 8 to 10, this operating body 15 is provided with a pair of notches 15e at the end on the switch portion 3 side, so that the operating body 15 moves a predetermined stroke l in the direction of the switch portion 3. When it moves, it is engaged with a pair of lock springs 19, and this engagement is caused by the operation body 1
5 is rotated by a predetermined angle, the lock spring 19 is removed from the notch 15e, and the lock spring 19 reaches the outer peripheral portion 15f of the operating body 15. Further, the lock spring 19 is held by a spring receiver 25, a locking groove 5b provided in the head case 5, and a through groove 5c. Furthermore, the operating body 15
rotates inside the head case 5 and rotates at a predetermined twist angle θ.

0 is provided between the outer periphery of the operating body 15 and the inner periphery of the head case 5, and has one end locked to the operating body 15 and the other end to the head case 5, and a spring receiver 5d provided on the head case 5. Operating body 15
It is held by a spring receiver 15g provided in the.

Next, the operation will be explained. When the operating button 14 is pushed, the operating body 15 connected to the operating button 14 moves in the direction of the switch portion 3 against the biasing force of the reset spring 20. When the operating body 15 moves by a predetermined stroke l, the notch 1 of the operating body 15
A lock spring 19 engages with the button 5e, and even if the push button 14 is stopped, the operating body 15 is locked in this position. In this state, the operating body 15 pushes the crossbar 13 of the switch section 3 to open and close the switch section 3 and to turn on the light bulb 22. Next, when necessary, turn the operation button 14 in the clockwise direction (arrow shown in FIG. 6).
When the operating body 15 is rotated (in the direction of RESET),

The engagement lock state between the notch 15e of 5 and the lock spring 19 is released, and the operating body 15 is released from the reset spring 2.
The twist is restored by a return force of 0, and the pressure on the cross bar 13 is released and reset. At this time, in conjunction with the operation of the operation button 14, that is, the opening/closing operation of the switch portion 3, the illumination display means, such as the light bulb 22, inside the operation button 14 receives an electrical signal and performs a blinking display.

In the above embodiment, the illumination display member is a light bulb, but it goes without saying that any light display member that can blink in response to an electrical signal from a switch portion may be used. Further, the operation button may be made of a translucent material, and may also have a hole in the front for confirming blinking.

As described above, this invention has a locking means that opens and closes the switch part when the operation button is pushed and locks this operation, and a lock means that releases the locked state and returns to the state when the operation button is twisted, and the switch part opens and closes. A reset spring for resetting the opening/closing operation of the switch is incorporated into the outer periphery of the operating mechanism part, and a hollow part is formed inside the operating mechanism part, and a reset spring is provided in the hollow part in conjunction with the opening/closing operation of the switch part. Since the operating display means is provided, there is an effect that the operating state of the device can be easily checked without increasing the size of the device.
