Abstract
Abstract A switch of the snap action type wherein a switch blade is pivotally carried by a combined bracket and terminal member which constitutes a part of the switch actuating overcentering mechanism, all of which has a construction whereby it may be easily and economically assembled within the switch housing. The combination bracket and terminal member is generally formed to provide spaced parallel base sections, with one of the base sections including a terminal portion disposed in coplanar relationship and extending laterally therefrom through one sidewall of the switch housing. The sidewalls of the switch housing each provide shelf members and retaining ribs positioned about the laterally disposed terminal portion as well as the medial portions of the terminal member for mounting the same thereto.

Claim 1
Independent Claim
216 words
A snap-action switch including the combination of a housing consisting of an interlocking case and cover, both of which have internally excavated confronting side walls and a switch actuating overcentering mechanism consisting of a movable switch blade and a coil spring, wherein the improvement comprises: a. a substantially U-shaped switch blade and coil spring supporting bracket having a center opening formed in its medial portion to provide spaced parallel base sections; b. a terminal member carried by said bracket and disposed in coplanar relationship and extending laterally from one of said base sections of said bracket; c. complementary shelf members provided by the spaced-apart confronting sidewalls of the case and cover supporting said spaced parallel base sections of said bracket within the internal cavities thereof; d. a confronting sidewall of said case having formed therein an elongated slot above and in horizontal alignment with said shelf member provided by the sidewall through which said terminal member of said bracket is adapted to project; and e. retaining ribs provided by the confronting sidewalls of the case and cover in vertical alignment with said shelf members and said slot for securing said base sections of said racket upon said shelf members and said terminal member in said slot so as to fixedly mount the same within the housing.
