Bimetal Button Contacts

Bimetal Button Contacts are button contacts made of bimetal, which combine high electrical conductivity with high mechanical strength. Excellent performance in harsh environments that need to withstand high pressures and high currents, such as automotive appliances, power control equipment, etc. The special design ensures stable contact, reduces wear and tear, and improves overall performance and durability.
