Method of preparing electrical contacts used in switches

Processes for preparing contacts on microswitches have been invented. The first is a wet process, involving the use of one or more acids, bases and peroxides, in some formulations diluted in water, to flush the contacts. The second process involves exposing the contacts to plasmas of various gases,...

Summary:Processes for preparing contacts on microswitches have been invented. The first is a wet process, involving the use of one or more acids, bases and peroxides, in some formulations diluted in water, to flush the contacts. The second process involves exposing the contacts to plasmas of various gases, including (1) oxygen, (2) a mixture of carbon tetrafluoride and oxygen, or (3) argon.
