Abstract:
1. An electrical switch comprising a housing, a polygonal array of pin terminals that are mounted to the housing and that have smooth burr-free surfaces facing towards each other along diagonal directions, and a rolling ball disposed movably inside the housing to bridge the pin terminals by contacting only the smooth burr-free surfaces of the pin terminals, wherein the electrical switch is produced by a method which comprises: forming the pin terminals by using a punching process; 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; wherein each of the pin terminals has a polygonal cross section, and includes at least one truncated pyramidal shaped end portion that has converging pyramidal corners, each of the pyramidal corners being a rounded corner that has the smooth burr-free surface.
