The pot piece (also known as metal dome, snap dome), the base material is made of stainless steel. Its thickness is generally between 0.05 mm and 0.10 mm. The pot piece is an important part of the switch. The pot is mainly used in membrane switches, contact switches, PCB boards, FPC boards, medical devices and other products.
The working principle of the pots is that when they are placed in the switch position, when you press the metal shrapnel hard, they touch the PAD on the PCB to turn the line on.
Generally, the conventional pots are divided into different shapes according to their different shapes: round pots, cross-shaped pots, triangular pots, and oval pots. Diameters range from 3mm to 20mm and strengths range from 100g to 6000gf. Through the continuous efforts of our R&D personnel, the life of the metal shrapnel has also been greatly improved, and generally it can reach a life of one million. According to the customer's requirements for electrical resistance, our metal shrapnel also has various surface treatments such as nickel plating, silver plating and gold plating.
