Low Profile-Low Bounce Electrical Switch Apparatus
View pageUS Patent:
39491811, Apr 6, 1976
Filed:
Sep 3, 1974
Appl. No.:
5/502959
Inventors:
Dean R. Kempf - Roseville MN
International Classification:
H01H 118
US Classification:
200159R
Abstract:
Extremely low bounce switching characteristics are achieved by biasing electrical switch conductors with a torsion beam member. The torsion beam member includes a torsion beam portion having an axis which is restrained from rotation thereabout at a first point and an operating beam portion connected to the torsion beam portion at a second point spaced from the first point. The axis of the operating beam is oriented at an angle with respect to the axis of the torsion beam such that displacement of the operating beam causes rotation of the torsion beam from a quiescent rotational state thus producing a torsional bias force against such displacement. At least one of the switch's electrical make/break conductors is operatively associated with the operating beam for displacement therewith while the remaining electrical conductor is disposed for making or breaking the electrical contact upon displacement of the operating beam. A special preferred embodiment includes complementary shaped mating unitary electrical conductors which are shaped so as to constitute both the torsion beam member and the electrical contact member of the switch. This preferred embodiment results in a very low physical profile and low bounce switch which has dual self-wiping electrical contacts and which is simply formed from only two unitary electrical conductors and two molded plastic members.
