Product List
There are usually several contact options when specifying switches for low energy switching, which is typically defined as less than 12V and lower than 0.4A. Silver contacts easily oxidize and a low-energy arc does not clean the contacts when switched, as does a high-energy arc. For any application where sulfides or moisture are present, silver contacts should not be used unless they are contained within a sealed switch. Sealed switches should also be used if particle contamination of the contacts is anticipated or if a film contaminant such as paint spray or oil mist is present in the application.
