Abstract: In a preferred embodiment, a snap switch which employs a conical contact mounted at the free end of a spring blade. The contact completes an electrical circuit by contacting and electrically joining two, round, spaced apart terminals. The resulting dual radii contact provides high unit pressure and a minimum of polymer-forming wiping action.

The terminal wires are of nickel with sleeves of oxidized nickel bonded thereto in the region where the wires pass through the base of the switch. The oxide provides a tenacious surface for the adherence thereto of sealing glass to insulatively bond the wires to the base.
