Abstract
A method of producing an electrical switch which includes a rolling ball movable within a housing thereof to bridge and contact an array of pin terminals includes the steps of forming the pin terminals by using a punching process, wherein one or more smooth burr-free surfaces are formed on each of the pin terminals; and assembling the pin terminals, the housing and the rolling ball by spacing apart the pin terminals along a polygonal line and by arranging the smooth burr-free surfaces of the pin terminals to face toward each other substantially along diagonal lines such that the rolling ball contacts only the smooth burr-free surfaces when bridging the pin terminals.
