Abstract
The utility model relates to a key switch provided with a contact-type LED lamp, comprising a fixed frame provided with a through hole in the middle, wherein the through hole is internally fixed with a functional component, and the front of the fixed frame is blocked and connected with a panel and a button cover; one side inside the functional component is provided with a seesaw and a line outgoing terminal corresponding to the seesaw, and the middle part at the other side thereof is provided with a line incoming terminal connected with the seesaw; the button cover is provided with a luminous source used for indicating switching on and off, one end of the luminous source is connected with an inserting piece which is conductive with the line outgoing terminal, and the other end thereof is connected with a contact pin which is conductive with the line incoming terminal; and a spring is respectively arranged between the line outgoing terminal and the inserting piece as well as between the line incoming terminal and the contact pin. As the LED lamp is arranged on the button cover, a contact way is specially designed for providing a power supply for the LED lamp; when the button cover is covered in place, the inserting piece is contacted with the spring, and the contact pin is also contacted with the spring, so that a circuit is connected; and when the button cover is disassembled, the inserting piece is separated from the spring, and the contact pin is also separated from the spring, so that no power is supplied for the LED lamp. The key switch is convenient for use, safe and beautiful in appearance.
Description
Technical field
The utility model relates to the switch on wall technical field, relates in particular to a kind of key switch with contact LED lamp.
Background technology
Have the fixed mount of through hole in the middle of existing key switch generally comprises, described through hole internal fixation has functor, and the fixed mount front is connected with panel and button cover, and the light emitting source that can indicate break-make is housed on the functor, and described light emitting source is generally the LED lamp.Yet traditional switch all is that the LED lamp is placed on the functor, and the power line of LED lamp is welded on the binding post, as making LED lamp power line with flexible cord, and the line that needs are long, and influence activity, installation and the outward appearance of button cover.In addition, electric shock accidents when installing or safeguarding, easily takes place owing to be to be in "on" position always in this kind structure, and is dangerous.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of easy to use, safe, and the key switch of the band contact LED lamp of appearance looks elegant.The utility model is achieved through the following technical solutions:
A kind of key switch with contact LED lamp of the present utility model comprises the middle fixed mount that has through hole, and described through hole internal fixation has functor, and the fixed mount front is connected with panel and button cover; Be provided with seesaw and the outlet terminal corresponding in the described functor on one side with seesaw, the another side middle part is provided with the input terminal that is connected with seesaw, the light emitting source that can indicate break-make is housed on the described button cover, light emitting source one end is connected with the inserted sheet that is conducted with outlet terminal, and the other end is connected with the contact pin that is conducted with input terminal; Be provided with spring between described outlet terminal and the inserted sheet and between input terminal and the contact pin.
As preferably, described button cover is provided with the mounting groove that the power supply source line passes.
As preferably, described inserted sheet is connected with light emitting source by power line, and described contact pin directly is connected with light emitting source.
As preferably, described light emitting source is the LED lamp.
The key switch of band contact LED lamp of the present utility model because the LED lamp is arranged on the button cover, has ad hocly for this reason been counted the way of contact LED lamp power supply is provided, when button cover is anchored to, inserted sheet contacts with spring, and contact pin also contacts with spring simultaneously, and circuit is with regard to conducting; When button cover was taken apart, inserted sheet separated with spring, and contact pin also separates with spring simultaneously, and the LED lamp is not powered.It is easy to use, safe, and appearance looks elegant.
Description of drawings
In order to be easy to explanation, the utility model is done to describe in detail by following preferred embodiment and accompanying drawing.
Fig. 1 is the three-dimensional exploded view of the key switch of the utility model band contact LED lamp;
Fig. 2 is the schematic diagram of the key switch button cover of the utility model band contact LED lamp;
Fig. 3 is the partial sectional view of the key switch of the utility model band contact LED lamp;
