Next, the operation of the above-described switch device will be described. First, when mechanically operated by a human finger or the like, the slide member 6 is moved by pressing the pressing portion 6g of the operating portion 6b against the urging force of the return spring 8, and the sliding member 6 is not shown. The lock cam is locked at the pressed position by the lock cam of the heart cam portion and the lock pin 9. At this time,
The movable contact 3 provided in the opening 6c of the slide member 6 swings when its swinging movement portion 3d is pressed by the operating groove 6d provided on one side of the opening 6c. The switch is turned on when the operation is reversed and the contact portion 3a comes into contact with the contact portion 4a of the fixed contact 4.

When the switch is turned off from this state, the lock pin 9 is released from the lock cam of the heart cam portion (not shown) by pressing the pressing portion 6g of the operation portion 6d again, and the slide member 6 is turned off. Is returned to an initial state before being pressed by the return force of the return spring 8, whereby the movable contact 3 is swung and reversed, and the contact 3 a is separated from the contact 4 a of the fixed contact 4. It turns off.

Next, when electrically operating by an electric signal, the condenser 29 on the electronic device side is operated by an electric signal of a remote control device or the like.
The electromagnetic coil 10 is energized by a discharge current from the capacitor 29. At this time, the metal arm 10b is rotatably disposed on the electromagnetic coil 10, and one end of the arm 10b is attracted to the arm 10b so that the arm 10b is connected to the other end. The fixed contact 4 is pressed and oscillated via the connecting member 7, and the contact portion 4 a is connected to the contact portion 3 of the movable contact 3.
a, and each contact is turned on.

In this case, the discharge current from the capacitor 29 for driving the electromagnetic coil 10 may be small enough to push and oscillate the fixed contact 4, so that the discharge current is composed of a capacitor on the electronic device side. It is possible to avoid a problem that the circuit becomes large because there is no need to increase the capacity of the power storage circuit, and a problem that it cannot be used in a circuit that can store only a small amount of energy (small capacity) in the power storage circuit. It has become.

Since the main circuit of the electronic device is turned on when the contacts are turned on, the electromagnetic solenoid 11 for attracting the slide is energized by the large electric power obtained from the main circuit. This energization causes the iron core 11 of the electromagnetic solenoid 11
is sucked, the slide member 6 is sucked and moved in the pressing direction via the connecting member 7 against the urging force of the return spring 8, and the lock cam of the heart cam portion (not shown) is locked by the lock pin 9. Locked in position. At this time, the movable contact 3 disposed in the opening 6c of the slide member 6 has its swinging motion portion 3d pressed by the operating groove 6d provided on one side of the opening 6c. As a result, the swinging is reversed, and the contact portion 3a is securely pressed by the contact portion 4a of the fixed contact 4 so that the switch is maintained in the ON state. At this time, the fixed contact 4 is formed in a leaf spring shape from a thin plate-shaped metal material, and is slightly bent in the pressing direction by the pressing force of the movable contact 3, and more reliable contact is obtained by this elasticity. It will be.

In this case, in order to drive the electromagnetic solenoid 11, the slide member 6 must be sucked and moved against the urging force of the return spring 8.
Although a large amount of electric power is required, the electromagnetic solenoid 11 is driven by electric power from a main circuit on the electronic device side, so that it is not necessary to store a large amount of energy in the electric storage circuit, and the circuit becomes large. Can be avoided.

Next, when the switch is to be turned off electrically, the electromagnetic solenoid 11 is used in the main circuit of the electronic equipment by an electric signal from a remote control device or the like.
Is released again, the iron core 11a is sucked, and the slide member 6 is again sucked and moved in the pressing direction via the connecting member 7, thereby releasing the lock pin 9 from the lock cam of the heart cam portion (not shown). Let
By returning the slide member 6 to the initial state by the return force of the return spring 8, the movable contact 3 is swung and inverted, and the contact portion 3 a is separated from the contact portion 4 a of the fixed contact 4 to switch. Is turned off.

FIGS. 4 and 5 show the structure of a switch device according to a second embodiment. FIG. 4 is a plan view showing a state in which a part of the switch device is broken, and FIG. Note that the same components described in FIGS. 2 and 3 are denoted by the same reference numerals and description thereof will be omitted.

In this case, the difference from the first embodiment is that the electromagnetic coil 10 which is a contact-on operating means for pressing and swinging the fixed contact 4 is replaced with a slightly smaller first coil.
The electromagnetic solenoid 13 is provided. That is, the first electromagnetic solenoid 13 is disposed on one end side of the storage portion 1a of the housing 1,
One end of an L-shaped connecting member 14 is attached to the tip of the iron core 13 a of the first electromagnetic solenoid 13, and the other end of the connecting member 14 is connected to the fixed contact 4. Further, the storage portion 1a of the housing 1
The second electromagnetic solenoid 15 is provided in parallel with the first electromagnetic solenoid 13 and has a slightly larger slide suction.
Is provided.

When the switch device having the above-described configuration is operated electrically, an electric signal from a remote control device or the like is used to operate the capacitor 2 on the electronic device side.
9 is turned on, and the capacitor 29 is turned on.
The first electromagnetic solenoid 13
Is energized. At this time, the first electromagnetic solenoid 13
The fixed contact 4 is pressed and oscillated through the connecting member 14 connected to the iron core 13a, and the contact portion 4a comes into contact with the contact portion 3a of the movable contact 3. The state between the contacts is turned on.

Also in this case, the discharge current from the capacitor 29 for driving the first electromagnetic solenoid 13 may be small enough to push and swing the fixed contact 4. It is not necessary to increase the capacity of the power storage circuit consisting of capacitors, etc., so that the circuit becomes large and the power storage circuit cannot be used in circuits where only a small amount of energy can be stored (small capacity). It is something that can be done.

Since the main circuit of the electronic device is turned on when the contacts are turned on, the second electromagnetic solenoid 15 for sucking the slide is powered by the large electric power obtained from the main circuit. Is energized, and this energization causes the second electromagnetic solenoid 1
5, the slide member 6 is sucked and moved in the pressing direction against the urging force of the return spring 8, and the lock cam (not shown) of the heart cam portion is locked at the lock position by the lock pin 9. You. At this time, the movable contact 3 disposed in the opening 6c of the slide member 6 has its swinging motion portion 3d connected to the opening 6c.
When the contact portion 3a is pressed by the operating groove portion 6d provided on one side of the fixed contact 4a,
The switch is maintained in the ON state by being reliably pressed by the contact portion 4a. At this time, the fixed contact 4
Is made of a thin plate-like metal material and is formed in a leaf spring shape, and is slightly bent in the pressing direction by the pressing force of the movable contact 3, so that more reliable contact can be obtained by this elasticity.

FIG. 6 shows the structure of the switch device according to the third embodiment, and FIG. 6 is a plan view showing a state in which a part of the switch device is broken. Note that the same components described in FIGS. 2 to 5 are denoted by the same reference numerals and description thereof will be omitted.

In this case, the difference from the first and second embodiments is that the contact-on operating means for pressing and swinging the fixed contact 4 and the driving member for sliding suction are constituted by one electromagnetic solenoid. Is a point. That is, the electromagnetic solenoid 1
Reference numeral 6 denotes a fixed contact 4 made of a substantially L-shaped leaf spring via a connecting member 17 at the end of an iron core 16 a of the electromagnetic solenoid 16. Is attached at one end. The central portion of the fixed contact 4 is supported by a swing support portion 1b provided on the inner bottom surface of the housing 1, and the other end of the fixed contact 4 is provided with the contact portion 4a. The iron core 16a includes a shaft portion 16b having a slightly smaller diameter and a shaft portion 16b.
A connecting arm 6h provided on the rear end side of the slide member 6 is loosely connected to the shaft 16b of the iron core 16a. ing. For this reason, the iron core 16a is engaged so as to be slidable in the suction direction independently of the movement of the slide member 6.

When the switch device having the above-described configuration is operated electrically, an electric signal from a remote control device or the like is used to operate the capacitor 2 on the electronic device side.

At this time, the fixed contact 4 attached to the iron core 16a via the connecting member 17 is attached. Is rotated about the swing support portion 1b as a fulcrum, and the contact portion 4a comes into contact with the contact portion 3a of the movable contact 3 to turn on each contact.

In this case as well, the discharge current from the capacitor 29 for driving the electromagnetic solenoid 16 may be small enough to attract and rotate the fixed contact 4, so that a capacitor or the like on the electronic device side may be used. Since it is not necessary to increase the capacity of the power storage circuit, the circuit becomes large, or only a small amount of energy can be stored in the power storage circuit (small capacity).
The problem that it cannot be used in a circuit can be avoided.

Since the main circuit of the electronic device is turned on when the contacts are turned on, the power supplied to the electromagnetic solenoid 16 is further increased by the large electric power obtained from the main circuit. As a result, the iron core 16a of the electromagnetic solenoid 16 is further attracted from the state in which it comes into contact with the connecting arm 6h, and the slide member 6 resists the urging force of the return spring 8. The lock cam of the heart cam portion 18 is locked at the lock position by the lock pin 9. At this time, the movable contact 3 disposed in the opening 6c of the slide member 6 has its swinging motion portion 3d pressed by the operating groove 6d provided on one side of the opening 6c. The rocking reversal
The switch is maintained in the ON state by reliably pressing the contact portion 3a against the contact portion 4a of the fixed contact 4. At this time, the fixed contact 4 is formed in a leaf spring shape from a thin plate-shaped metal material, and is slightly bent in the pressing direction by the pressing force of the movable contact 3, and more reliable contact is obtained by this elasticity. It will be.

According to the above-described embodiment, the electromagnetic solenoid as the operating means for turning on the contact and the electromagnetic solenoid as the driving member for sliding attraction are constituted by one electromagnetic solenoid 16, so that components are provided. The number of points is reduced, and the switch device can be reduced in size and inexpensive.

FIGS. 7 and 8 show the structure of a switch device according to a fourth embodiment. FIG. 7 is a partial sectional view showing a state where a detection switch is mounted, and FIG. is there. Note that the same components described in FIGS. 2 to 6 are denoted by the same reference numerals and description thereof will be omitted.

In this case, the difference from the first to third embodiments is that the rear portion of the housing 1 of the switch device 32 is
The point is that a detection switch unit 19 operated in conjunction with the movement of the slide member 6 is provided. That is, a pair of contact portions 2 opposed to each other is provided at the rear portion of the housing 1.
0a, 20b are provided, and a contact end 20a, 20b of the detection switch 19 is pressed at a rear end of the slide member 6 to contact each contact 20a, 20b. A pressing projection 6i for connecting the spaces is provided, and when the slide member 6 is locked at the lock position, the detection switch 19 is turned on by the pressing projection 6i.

By providing the detection switch portion 19 at the rear of the housing 1, when the slide member 6 is locked at the lock position by suction by energizing the electromagnetic solenoids 11, 15, 16, the detection switch portion is provided. Based on the ON signal of the section 19, the electromagnetic solenoid 11,
Since control can be performed so as to stop energization of the solenoids 15, 16, a control circuit for controlling the energization time of the electromagnetic solenoids 11, 15, 16 is not required, and power saving can be achieved.

According to the above-described embodiment of the switch device of the present invention, the contact portions 3 and 4 which are brought into contact with and separated from the sliding member 6 are movably disposed on the housing 1. The contact portion 3 is provided on the housing 1.

After the electromagnetic coil 10, the first electromagnetic solenoid 13, or the electromagnetic solenoid 16 operates the contact portions 3 and 4 to turn on the contact portions 3 and 4, the gap between the contact portions 3 and 4 is established. The electromagnetic solenoids 11 and 16 for sliding suction and the second electromagnetic solenoid 1
5 is driven to move the slide member 6 to the lock position, so that the discharge from the capacitor 29 for driving the electromagnetic coil 10, the first electromagnetic solenoid 13, or the electromagnetic solenoid 16 is performed. The electric current may be small enough to operate the contact portions 3a, 4a, and the electromagnetic solenoids 11, 16 and the second electromagnetic solenoid 1 for sliding suction may be used.
5 can be driven by power from a main circuit on the electronic device side, so that it is not necessary to store large-capacity energy in a power storage circuit including the capacitor 29 and the like on the electronic device side, and the circuit becomes larger. It is possible to solve the problem and the problem that it cannot be used in a circuit in which only a small amount of energy can be stored (a small capacity) in a power storage circuit.

Since the operating device is driven to securely hold the switch device in the ON state, the switch can be operated with a small capacity without increasing the capacity of the power storage circuit consisting of the capacitors on the electronic device at the time of auto-on. In addition to being able to be turned on, the power storage circuit and elements used therein can be reduced in size, so that the electric circuit portion of the electronic device can be simplified and downsized.

The switch device further comprises a housing, a slide member slidably provided in the housing, a contact portion which is brought into contact with and separated from the slide member, and a slide member connected to the slide member. A driving member for moving in the locking direction,
The housing is provided movably, and the housing is provided with an actuating means for actuating the contact section.When the automatic operation is performed based on a signal from the control circuit, the contact section is actuated by the actuating means before the slide member moves. After turning on the contacts and turning on the contacts, the drive member is driven by the current flowing through the contacts to move the slide member to the lock position. The switch can be turned on with a small capacitance without increasing the capacitance of the circuit, and the power storage circuit and elements used therein can be reduced in size.

Further, since the actuating means is constituted by an electromagnetic coil or an electromagnetic solenoid, it can be driven by a power storage circuit, so that it is not necessary to increase the capacity of a power storage circuit including a capacitor or the like on the electronic device side. In addition, the size of the circuit can be reduced.

Also, the driving member is made of an electromagnetic solenoid, the driving member and the actuating means are composed of one electromagnetic solenoid, and the electromagnetic solenoid is connected to the contact portion and the slide member. And the switch device can be reduced in size and inexpensive.

Further, the switch device is provided with a detection switch section which is operated in conjunction with the movement of the slide member, and when the slide member is locked at the lock position, the drive member is controlled based on a signal from the detection switch section. Since the energization is stopped, a control circuit or the like for controlling the energization time of the electromagnetic solenoid becomes unnecessary, and it is possible to cope with power saving.
