Abstract

The invention provides a button switch with a dual-redundancy overtravel and a full sealing function. The button switch comprises a shell, an upper seat, an overtravel mechanism and a base assembly, wherein the upper seat, the overtravel mechanism and the base assembly are all mounted in a limiting block; the upper seat and the overtravel mechanism at the middle part of the shell; the base assembly is mounted at the lower end of the limiting block; reset devices are arranged between the upper seat and the overtravel mechanism and between the limiting block and the base assembly; and a sealingdevice is arranged on the shell. The button switch is capable of normally working under the condition of unbalance load pressing, so that the reliability of the switch is ensured.

Description

technical field [0001] The invention relates to a button switch with double redundancy overtravel and full sealing function. Background technique [0002] The push button switch is a switch that drives the internal contact conversion by the driving force on the same line as the push button stroke. It is an important component in consoles and panel control systems of various instruments, meters, and electromechanical equipment; Under the action of switching to the second state, when the external force is removed, due to the action of the spring, the switch returns to the initial position. [0003] When the button switch is working, it is often caused by abnormal contact of the switch due to partial load pressing. In order to avoid this phenomenon, the method currently adopted is to strictly control the coordination clearance of each action mechanism of the switch. However, there are problems such as high difficulty, low efficiency, low pass rate, and high cost only by stri...
