Contact switch structure

Abstract

The invention discloses a contact switch structure, which can be used to prevent negative influences of dust and impurities on contact performance of a switch, can be used to maintain good contact of switch contacts, is stable, and is provided with an anti-excessive deformation function. The contact switch structure comprises a dynamic contact part, a static contact part, a pressing outer button, and a conductive contact body. The static contact part comprises a static contact pedestal, which is provided with a pedestal plate, and the pedestal plate is provided with a conductive part. The conductive contact body is provided with a plurality of bent reeds. The pressing outer button is slidably connected with the static contact pedestal, and a reset spring capable of resetting the pressing button is disposed between the pressing outer button and the static contact pedestal. The conductive part is in the shape of a net. The contact switch structure is advantageous in that the reeds and the net-shaped conductive part are used to replace the routine contacts, and then the adhesiveness of the dust and the impurities can be weak, and the contact maintaining effect can be better; the buffering capability and the position-restricted protection structure can be provided, the fast excessive deformation of the internal structure and the large impact can be prevented, and the service lifetime can be prolonged.

Description

technical field [0001] The invention belongs to the field of special switches for automobiles, and in particular relates to a contact switch structure. Background technique [0002] In a car, there are many switches, such as various light switches on the dashboard, etc., and the number of contact switches is also very large. The contact switch on the car pays attention to timeliness and stability. If it fails or fails, it will easily cause safety problems. Contact switches are generally divided into moving contacts and static contacts. The contact part is the core position. If there are dust and impurities in the switch, it is easy to cause poor contact; moreover, sometimes people in the car tend to press the switch too quickly. Or use too much force, which will easily cause the contact switch to be impacted or deformed too quickly, causing it to be easily damaged. Contents of the invention [0003] The present invention aims to overcome the deficiencies in the prior art...
