Metal contact spring is mainly used in membrane switches, micro switches, PCB boards and other products. It plays an important role in the conduction circuit and is an important part of the switch. With the continuity of metal shrapnel, it is in the operator and product. Play a quality switch.
The metal shrapnel has a long life of up to 500,000 to 1 million times, which fully demonstrates the advantages of smooth contact, strong continuity, stable rebound and good hand feeling. Generally, the conventional metal shrapnel is divided into different shapes according to different shapes: a circular metal shrapnel, a cross-shaped metal shrapnel, a triangular metal shrapnel, and an elliptical metal shrapnel. The diameter ranges from 3mm to 20mm, the strength ranges from 100gf to 600gf, and the surface is nickel-plated, silver-plated, gold-plated, etc., and can also be produced according to customer's drawings/requirements.
