Description

A self-locking button switch with light

technical field

The utility model belongs to the technical field of button switches and relates to a self-locking button switch with a lamp.

Background technique

Today, push button switches have been widely used in various fields such as electronic appliances, instruments and meters, electromechanical equipment, broadcasting communications, household appliances, medical equipment, automobiles, and automation control. People's requirements for push button switches are also getting higher and higher. As the cost of components is getting higher and higher, the production cost and purchase price of push button switches are also rising. Therefore, the development of economical push button switches has gradually become a trend. The existing economical pushbutton switches are often complex in structure, with three or even multi-segment structures. The overall height of the pushbutton switch is relatively high, it takes up a large space, and its application range is limited; The installation steps are cumbersome. In addition, the existing economical push button switches often cannot be equipped with lights and have a self-locking function at the same time, so they cannot fully meet the needs of the market.

Utility model content

The purpose of this utility model is to provide a self-locking push button switch with light with low overall height and easy installation in order to overcome the above-mentioned defects in the prior art.

The purpose of this utility model can be achieved through the following technical solutions:

A self-locking button switch with a light, the button switch includes a button, a push rod self-locking mechanism connected to the button, a casing sleeved outside the push rod self-locking mechanism, and a push rod self-locking mechanism arranged in the casing and connected to the push rod self-locking mechanism. An integrated contact light mechanism with transmission connection, the integrated contact light mechanism includes a contact base, a light assembly arranged on the contact base, and a contact assembly arranged on the contact base and connected to the push rod self-locking mechanism in transmission, The push button switch controls the on and off of the circuit through the contact assembly.
