Abstract
Embodiments relate generally to systems and methods for preventing arcing within a snap action switch, particularly by removing a portion of a contact carrier attached to a stationary contact. A method of forming a contact for use in a snap action switch may comprise welding a contact onto a contact carrier; trimming at least one edge of the contact carrier proximate to the contact; and installing the contact carrier into a snap action switch housing. Trimming the at least one edge of the contact carrier may also comprise removing flash formed during the welding of the contact to the contact carrier.
