Bimetal Plum Blossom Button Contacts

Bimetal Plum Blossom Button Contacts combines the excellent properties of different metals, such as high electrical conductivity and good elasticity. The unique torcunx shape design increases the contact area and improves the conductive efficiency, which is suitable for precision electrical control equipment.

General Description

Bimetal contact buttons can be supplied in a large varitey of configurations and combinations of materials, The material of the working layer may be Ag,AgCdO or AgNi,Forthe side to be welded to the support material steel or Cu-Ni alloy can be used,The thickness of top working layer is within half of the top layer thickness .In the standard design the contactbuttons have 3,5or7 spherical projections,Other numbers of projections and shapes of the projections,however,are also possible
