Problems solved by technology
And there are still many push button switches that do not meet the life test requirements of 1 million times. Although the button panel can be pressed at any position, it will be triggered, but the structure is relatively complicated, the cost is very high, and the installation process is very complicated.

The invention discloses a push button assembly for rail transit, which comprises a PVC connection fastening sleeve, a first button housing, a first circuit board, a guide cover plate A and a button arrow panel A, A first circuit board is fitted and installed in the circuit board cavity of the first button housing, a button arrow panel A is installed on the outside of the guide cover plate A, threeelectric contact keys A are arranged on the first circuit board, a spring is fixed in the center of the first circuit board, and the spring is fixedly connected with the center of the button arrow panel A through a through hole of the guide cover plate A; A guide cover plate A is provided with a first electric connection arc block A and a second electric connection arc block A, and a first indicating button A and a second indicating button A are provided on the outside of the button arrow panel A; A plurality of LED lamps A are also electrically connected to the first circuit board along theedge. The button arrow mark panel is press, the corresponding key contact are triggered, the LED indicator light in the circuit board is lit, and the corresponding button arrow mark panel is emitted through the edge of the circuit board or illuminated.
Description
Technical field [0001] The invention relates to a push button assembly, in particular to a push button assembly used in rail transit. Background technique [0002] The pressing button in the prior art uses a compression spring as the contact point. Although it meets the requirements of the life test of 1 million times, it is difficult to achieve that the button panel will be triggered when pressed at any position. After the push button is triggered, the LED light passes through the shell design of the light guide, and the light is emitted through the light guide. In addition, there are many push button switches that do not meet the requirements of 1 million life tests. Although the button panel can be triggered at any position, the structure is relatively complicated, the cost is very high, and the installation process is very complicated. Summary of the invention [0003] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a push butt...
