Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1 to 2, a single-gang multi-control switch device includes a self-locking switch 10 and more than two self-resetting normally-open switches 20 that can be pressed by a user, in this embodiment, the initial state of each resetting normally-open switch 20 is an open state, each resetting normally-open switch 20 is switched from the open state to a closed state when being pressed, and is returned to the initial state (i.e., the open state) when the pressing force is removed; in this embodiment, the shape of the respective reset normally-open switches 20 can be made to be the same as that of 86-type panel switches; the number of the self-resetting normally-open switches is 4, however, the number of the self-resetting normally-open switches is not limited to the number shown in the figure, the number of the self-resetting normally-open switches can be 3, 5, 10 and the like, and each self-resetting normally-open switch 20 can be arranged at one control place, so that multiple controls can be realized.

The self-locking switch 10 comprises a button 101, and the self-locking switch 10 is switched between open and closed when the button 101 is pressed, in the embodiment, the self-resetting normally-open switch 20 and the self-locking switch 10 both adopt the prior art, and are not described herein again;

the single-linkage multi-control switch device also comprises an electromagnet 30 and an actuating mechanism 40;

all the self-resetting normally-open switches 20 are connected in parallel and then are connected in series with the electromagnet 30, so that the electromagnet 30 is electrified (namely electrified) when any one self-resetting normally-open switch 20 is pressed (namely, switched from an open state to a closed state);

the actuator 40 is provided between the electromagnet 30 and the self-locking switch 10, and the actuator 40 presses the button 101 when the electromagnet 30 is energized. In this embodiment, the actuator 40 presses the button 101 once every time the electromagnet 30 is energized.

The actuator 40 includes a lever 404;

one end of the lever 404 is provided with a head 401 for tapping to press the button 101, and the other end of the lever 404 is provided with the return spring 50 and an iron piece 402 which can be attracted by the energized electromagnet 30;

the lever 404 pivots about the fulcrum 403 between a depressed position and a raised position, the head 401 tapping to press the button 101 when the lever 404 is pivoted from the raised position to the depressed position;

the lever 404 is rotated from the raised position to the depressed position when the electromagnet 30 is energized;

the return spring 50 is arranged so that the lever 404 always has a tendency to return to the raised position.

In this embodiment, the operating principle of the actuator is as follows:

as shown in fig. 2, the lever of the actuator is at a lifted position, the button of the self-locking switch is lifted, and the self-locking switch is in a power-off state.

As shown in fig. 3, when the electromagnet is powered on, the lever of the actuator rotates from the lifting position to the pressing position, the button of the self-locking switch is pressed by the head, and the self-locking switch is in a closed power-on state.

As shown in fig. 4, when the electromagnet is powered off, the lever of the actuator is rotated from the pressing position to the lifting position under the action of the return spring, and due to the characteristics of the self-locking switch, the button is locked after being slightly lifted, and waits for being pressed again, and at the moment, the self-locking switch is still in a closed power-on state.

In this embodiment, besides the above structure, the actuator may also adopt the prior art, such as the movement of the armature component and the push rod head in the relay electromagnet component in the latching relay disclosed in chinese utility model patent specification CN 203225220U to drive the movement of the nut and the latching button head of the latching switch.

The utility model discloses a plurality of from normal open switch that restores to throne install respectively in the different needs and control the part, reach the purpose of controlling many places. The self-locking switch, the electrical appliance (such as a lighting lamp) and the power supply form a loop, and the self-resetting normally-open switch, the electromagnet and the power supply form another loop.

The electromagnet is electrified when any self-reset normally-open switch is pressed, the lever of the actuating mechanism is driven to overcome the acting force of the reset spring and rotate to the pressing position from the lifting position, the head of the lever is knocked to press the button of the self-locking switch in the rotating process of the lever, the self-reset normally-open switch returns to the initial state (namely the disconnection state) when the pressing force is cancelled, the electromagnet is electrified, and the lever of the actuating mechanism rotates to the lifting position from the pressing position under the action of the reset spring, namely the lever resets.

In this embodiment, the button of the self-locking switch can be in a closed power-on state when being pressed once, and the button of the self-locking switch is switched from the closed power-on state to an open power-off state when being pressed again.

The utility model has the advantages of as follows:

1. the utility model can realize multi-place control, the number of control points is not limited, the use is flexible, and the use in a wider range is satisfied;

2. the utility model has simple wiring, clean loop and convenient installation and maintenance;

3. the electromagnet is in a disconnected state at ordinary times, and electric energy is saved.
