ABSTRACT:
An electric switch especially adapted for use in a variety of keyboard applications includes an elongated and generally straight wire beam spring which is fixedly supported at its ends in the switch housing with a center portion free to be flexed relative to the ends of the spring. The normal position of the wire beam spring has the center portion spaced from a pair of spaced contacts and an actuator mounted on the switch housing is depressed to flex this center portion from its normal position into engagement with the contacts and thereby close an electric circuit between such contacts.
