Application Scope
Trimetal rivets are normally used as double side contacts,mainly used in relays, micro switches,button switches and contactors.
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
PRODUCT MATERIAL
Bimetal Rivets: Ag.FAg.AgNi.AgCdO.AgSnO2.AgSnO2In2O3.AgZnO.AgCu.CuNi.Cu
