Abstract
There is provided a method of producing a contact switching device comprising a step of pressing an electrically conductive metal sheet to form a lead frame having at least one relatively resilient contact member extending from one of the terminal portions and a stationary contact member extending from the other terminal portion, the relatively resilient contact member and the stationary contact member being disposed in mutually opposed and spaced apart relation, a step of bending external rim portions of the lead frame while the relatively resilient contact member is biased in such a manner that the opposed relatively resilient contact member and stationary contact member are brought together into partially overlapping relation, a molding step for forming an insulating base at base portions of the two terminal members, and a terminal-forming step of cutting the lead frame to leave the two terminal portions. The contact switching device as produced in the above manner, which has several advantages, is also described.
