Abstract

The invention discloses a universal micro switch with a forced separation function. The universal micro switch comprises a normally-closed connector, a movable contact spring, an elastic part and a press button, and also comprises a forced separation part, wherein one end of the forced separation part is mounted on a shell through a rotating shaft, and the other end of the forced separation part abuts against the movable contact spring; and the normally-closed connector and the movable contact spring are separated through linkage of the press button in a forced manner. The press button is usedfor triggering the elastic part and the movable contact spring, and after a switching position of the switch is reached, the forced separation part is triggered in a linkage manner, so that the separation of the normally-closed connector and the movable contact spring is guaranteed. Compared with the prior art, the switch is additionally provided with the forced separation part so as to realize the forced separation function, safer and more reliable application of the switch in the industry is guaranteed, and the universal micro switch has wide application prospects.

Description

technical field

[0001] The invention belongs to a micro switch, in particular to a universal micro switch with forced separation. Background technique

[0002] The micro switches on the existing market are equivalent to standard parts used in the market, and all micro switches are basically unable to achieve forced separation. The reasons are as follows:

[0003] 1. The overall structural size of the micro switch is small, the internal space of the switch is small, and the components in the internal space are compact. When the size of the switch installation hole remains unchanged, the switch cannot be enlarged, and it is basically difficult to add additional forced separation parts.

[0004] 2. Most of the micro switches are self-resetting by extension springs, reeds or integral shrapnel. In the initial state, the contacts on the movable contact piece of the switch are usually in contact with the contacts on the normally closed connector. The rocker movement mode is used t...
