Tongda Waterproof Micro Switch Push Button Micro Introduction
Waterproof micro switch is a switch device for working in wet or water environment.The switch adopts a special sealing structure, which can effectively prevent moisture from entering the inside of the switch.The contact part of the switch is made of waterproof material, which has good waterproof performance.
The working principle of the waterproof micro switch is based on the contact resistance generated by the current passing through the contacts.When current passes through the switch, the contact resistance between the contacts will change, triggering the action of the switch.
