[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 to 3 show an embodiment of a pushbutton switch device with a solenoid according to the present invention. 1 to 3, the pushbutton switch device with solenoid is constituted by a pushbutton switch device 11 and an electromagnetic solenoid 12 connected thereto. In the push button switch device 11, a cover 13 is attached to the case 13. A common contact piece 15 and a fixed contact piece 16 that constitute a switch mechanism SW are provided at the bottom of the case 13, and a movable contact piece 17 is rotatably provided on the common contact piece 15. An operation element 18 is provided on the case 13 so as to be able to enter and exit. At the inner end of the case of the operation element 18, a pressing element 19 is provided so as to be able to move in and out in a direction orthogonal to the moving direction of the operation element. The pressing element 19 is urged in a projecting direction by a spring 20 housed in the operating element 18, and is slid on the upper surface of the movable contact piece 17. In the switch mechanism, the movable contact 17 is rotated by the pressing member 19 moving on the upper surface of the movable contact 17 in response to the operation of the operating member 18, and the movable contact 17 is fixed to the common contact 15 by the rotating member 17. The switch state is set to ON or OFF by making contact with or separating from the fixed contact piece 16.

A so-called heart cam 21 that constitutes a lock mechanism LK is provided on the surface of the operation element 18 inside the case and along the movement direction. One end of a pin 22 as an engaging member is engaged with the heart cam 21, and the other end of the pin 22 is rotatably held by the case 13 through a long hole 23 provided in the operation element 18. . The length of the long hole 23 corresponds to the moving distance of the operation element 18. A stopper member 24 is provided on a portion of the operation element 18 located outside the case 13. Between the stopper member 24 and the other end of the pin 22, for example, a coil spring 25 is provided as an elastic member. The coil spring 25 urges the operation element 18 in a direction protruding from the case 13 and urges one end of the pin 22 so as to press against the surface of the heart cam 21.

On the other hand, a plunger 26 is provided on the electromagnetic solenoid 12 so as to be able to enter and exit. The tip of the plunger 26 is engaged with the inner end of the case of the operation element 18, and the operation element 18 and the plunger 26 are linearly arranged as shown in FIG. The electromagnetic solenoid 12 is provided with a pair of terminals 27. The electromagnetic solenoid 12 is excited according to an electric signal supplied to the terminal 27, and the plunger 26 is attracted into the electromagnetic solenoid 12. When no electric signal is supplied to the electromagnetic solenoid 12, the plunger 26 is in a free state.

The operation of the above configuration will be described. First, the manual operation will be described. The operation by this manual operation is the same as that of a normal push button switch device. That is, in a state where no electric signal is supplied to the electromagnetic solenoid 12, as shown in FIGS. 1 to 3, when the operation element 18 is at a position protruding from the case 13, the switch mechanism SW is turned off. . When the operating element 18 is pushed into the case 13 from this state, the movable piece 17 is rotated by the pressing element 19 and comes into contact with the fixed contact piece 16, and the switch mechanism is turned on. At this time, the one end of the pin 22 is engaged with the locking position of the heart cam 21, and even if the pressing force on the operating member 18 is released, the operating member 18 is held at the pushed-in position, and the switch mechanism is turned on. Will be kept. When the operator 18 is pushed again in this state, the engagement state between the pin 22 and the heart cam 21 is released. Therefore, when the pressing force on the operation element 18 is released, the operation element 18 is returned to the position shown in FIGS. 1 to 3 by the urging force of the coil spring 25, and the switch mechanism is turned off.

Next, an operation using the electromagnetic solenoid 12 will be described. When a pulse-like electric signal is supplied to the electromagnetic solenoid 12 in the state shown in FIGS. 1 to 3, the electromagnetic solenoid 12 is momentarily excited, and the plunger 26 is attracted to the electromagnetic solenoid 12. Therefore, the operator 18 is pulled into the case 13 in the same manner as when pressed by manual operation, and the switch mechanism is turned on. When the pulse-shaped electric signal is cut off, the electromagnetic solenoid 12 is demagnetized, so that the plunger 26 is in a free state, and the operating element 18 attempts to return by the urging force of the coil spring 25. The operating element 18 is locked by the lock mechanism LK. Therefore, the switch mechanism is kept in the ON state. In this state, when, for example, a pulse-like electric signal is supplied to the electromagnetic solenoid 12 again, the electromagnetic solenoid 12 is momentarily excited, and the plunger 26 is attracted to the electromagnetic solenoid 12. Therefore, the operation element 18 is pulled into the case 13, and the engagement state between the pin 22 and the heart cam 21 is released. When the pulse-shaped electric signal is cut off, the electromagnetic solenoid 12 is demagnetized, so that the operating element 18 is returned to the position shown in FIGS. 1 to 3 by the urging force of the coil spring 25, and the switch mechanism is turned off. Become.

It is also possible to combine the above-mentioned manual operation with the operation using the electromagnetic solenoid 12. For example, the switch mechanism is manually turned on, the electromagnetic switch is turned off using the electromagnetic solenoid 12, and the switch operation is performed using the electromagnetic solenoid 12. An operation mode in which the mechanism is turned on and manually turned off is possible.

According to the above-described embodiment, the plunger 26 of the electromagnetic solenoid 12 is connected to the operator 18 of the push button switch device 11 and the electromagnetic solenoid 12 is instantaneously excited by an electric signal. The operator 18 is operated in the same manner as the manual operation via. Therefore, the push button switch device 11 can be set to the ON state and the OFF state by using the electromagnetic solenoid 12.

As described above, the switch device according to this embodiment can be set to the ON / OFF state by an electric signal. Therefore, in an electronic apparatus to which the switch device is applied, for example, the switch device is controlled by a timer device. By turning on and off the main power supply of the electronic device in this way, it is possible to prevent the automatic operation of the electronic device and forgetting to turn off the power, thereby saving energy.

Moreover, since the plunger 26 of the electromagnetic solenoid 12 is directly connected to the inner end of the case 13 of the operator 18 of the push-button switch device 11, no additional components are required for connecting these. Therefore, it is possible to prevent an increase in the number of parts and to reduce the number of assembling steps.

[0016] Further, a large load is not applied to the pins and the cam as compared with the case where the pins constituting the conventional lock mechanism are driven by the electromagnetic solenoid and the plunger. This has the advantage of reducing the probability of failure.

In the above embodiment, the plunger 26 and the operation element 18 are connected so as to be linear. However, if the above operation can be realized, the connection position between the plunger 26 and the operation element 18 is However, the present invention is not limited to this. In addition, the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.
