Abstract
The invention relates to an electrical type contact switch assembly. The assembly includes an insulated contact carrier having a U-shaped portion with spaced apart walls. A slot for receiving a leaf spring extends transversely through the walls. Mutually facing depressions formed in the walls straddle the slot and have oppositely inclined surfaces. A leaf spring disposed in the slot has a resiliently hinged flap extending at an acute angle relative to the plane of the spring. The flap is in resilient biasing engagement with the inclined surfaces of the contact carrier. The flap is of trapezium shape and is an integral part of the spring.
Claims3
A contact switch assembly comprising an insulated contact carrier having a U-shaped portion with spaced apart walls, a slot extending transversely through said walls, mutually facing recesses formed in said walls on at least one side of said slot, said recesses having oppositely inclined surfaces, a leaf spring contact in said slot having an attached resiliently hinged flap extending at an acute angle relative to the plane of said leaf spring contact, said flap having sharp corners at opposite ends thereof which dig into said inclined surfaces of said recesses to hold said flap in resilient biasing engagement with said inclined surfaces of said carrier to hold said leaf spring contact firmly in an inserted position.
