Abstract
A leaf spring contact with endwise applied actuation movement is provided with a leaf spring body having two ends, at least one contactor located upon the center of said leaf spring body and two inflexible and laterally immovable anchors, each fastened to a different end of said leaf spring body. Means are connected to at least one of said anchors for directing a compressive force through said one anchor towards the center of said leaf spring body and for, consequently, inducing a transgression of bending stress of said leaf spring body which then suddenly bends in a whip-like fashion resulting in switch motion of said leaf spring body.
Claims5
A movable leaf spring contact engageable with a fixed contact for switching the same, said leaf spring comprising a normally straight leaf spring body having two end portions and an intermediate portion therebetween;
- two rigid and laterally immovable anchors each rigidly embracing a different end portion of said spring so as to prevent all lateral movements of said end portions;
- and means connected to at least one of said anchors for directing through said one anchor and the respective end portion fastened thereto a compressive force which acts lengthwise of said spring body and towards the center of the same and for inducing a consequent transgression of bending stress of said intermediate portion of said leaf spring body which intermediate portion then suddenly bends and engages a fixed contact.
