What is the difference between a regular button and a metal button? A metal button switch is a type of metal push-button switch, including metal membrane switches, anti-roll metal switches, and metal proximity switches. Metal membrane switches have a very thin metal film, and anti-roll metal switches are mainly used in various cranes for metal-based closing. These switches are manufactured by foreign companies.
The switching assembly of a metal button switch is a rocker-arm type double-contact switch assembly. It consists of a switch base, a bracket mounted on the switch base, a stationary spring fixed to the switch base, a lower stationary spring, and a moving contact between the upper and lower stationary springs. One end of the moving contact is hinged to the cantilever end of a movable spring plate mounted on the bracket, and the other end of the moving contact is connected to a tension spring. The other end of the tension spring is connected to the bracket. A push block contacts the tension spring of the moving contact and extends from the top of the switch and the bottom of the switch base. Because metal button switches use a rocker-arm type double-contact switching element, their switching action is faster, the touch stability during operation is better, and they can adapt to a wider range of current and voltage applications.
