Description

Wall switch with resettable push plate

Technical field:

The utility model relates to the technical field of a wall switch, in particular to a wall switch with a resettable pressing plate, which can maintain the original state no matter whether it is turned on or off.

Background technique:

With the development of science and technology and the progress of society, people pay more and more attention to the decoration of houses. Of course, this includes a very important item: wall switch. Nowadays, people's requirements for wall switches are not only durable, but also pay more attention to its beautiful appearance. Currently the most widely used wall switch, its structure is shown in Figure 1. It includes a housing, a press board 02, and an inner switch device driven by the press board 02. The inner switch device is mainly moved up and down by the seesaw button 042. The spring 044 at its lower end controls the contact and disconnection of the movable contact piece 064 and the conductive piece 062, thereby controlling the whole circuit. This structure is universal, but it will appear unsatisfactory during use: when pressing the button 02, one end of the seesaw button 042 is pressed, and the other end of the seesaw button is pushed upwards, which will inevitably make the button 02 The other end is also tilted up. Usually, people will make a mark on the top of the press board to mark whether the switch is turned on or not. However, in many conference venues, such as business centers and other places where wall switches are installed more, the press boards of some switches are upward. Rocking, the other switches do not move, which greatly affects the overall appearance.

Utility model content:

The purpose of this utility model is to provide a wall switch with a resettable push plate in view of the deficiencies of the prior art. Regardless of whether it is turned on or off, the push plate can maintain the original state without affecting the shape of the wall switch.

In order to achieve the above purpose, the utility model adopts the following technical scheme: it includes an outer shell, a pressing plate matched with the outer shell, a bracket for supporting the pressing plate, a bottom case and a circuit board fixed in the bottom case; one end of the pressing plate The fixed other end is movable; the circuit board is electrically connected with a pawl-type switch element, and when the movable end of the pressing board is pressed down, it will touch the button of the pawl-type switch element, thereby realizing the "on" and "off" of the wall switch.

The bracket is molded with movable shrapnel, and other auxiliary elastic objects can also be added.

The utility model adopts a pawl-type switch element that can be automatically reset by pressing the button. When the pressing plate is pressed down, the pawl-type switching element is turned on, the circuit is turned on, and the pressing plate is released, and the pressing plate is automatically reset; when the pressing plate is pressed again , the circuit is disconnected, and the pressing board remains in its original state; whether it is turned on or off, it does not affect the overall appearance.

Description of drawings:

Below in conjunction with accompanying drawing, the utility model is further described:

Fig. 1 is the structural schematic diagram of existing wall body switch;

Fig. 2 is a schematic structural view of the utility model.

Detailed ways:

See accompanying drawing 2, the utility model comprises: outer casing 10, the pressing plate 12 that cooperates with outer casing 10, the support 20 that is used to support pressing plate 12, bottom shell 40 and the circuit board 30 that is fixed in bottom shell 40. One end of the pressing plate 12 is fixed and the other end is movable, that is, only the movable end of the pressing plate 12 can be pressed.

The circuit board 30 is electrically connected with a pawl-type switch element 32 , which is an existing product on the market, and details will not be repeated here. The switch button of the ratchet switch element 32 can be automatically reset, and each time the switch button is pressed, the circuit inside it will automatically switch between the on and off states.

When the movable end of the pressing plate 12 is pressed down, it resists the button 34 of the pawl type switch element 32 . Because the utility model is generally installed on the body of wall, the button 34 of the pawl type switch element 32 can push the pressing plate 12 outwards, that is, after the pressing plate 12 is released, the button 34 of the pawl type switch element 32 can Make pressing plate 12 reset.

In order to enhance the reset effect of the pressing plate 12 , a movable shrapnel 22 can be formed directly on the bracket 20 to increase the restoring force of the pressing plate 12 .

Of course, other elastic objects can also be added between the pressing plate 12 and the bracket 20, so as to enhance the restoring force of the pressing plate 12 when it is automatically reset and the feeling effect when pressing.

The utility model adopts the pawl type switch element 32, regardless of whether the switch is on or not, the pressing plate 12 is automatically reset, the shape is kept unchanged, and the structure is relatively simple.
