TRIGGER OPERATED TOOL HANDLE SWITCH ABSTRACT OF THE DISCLOSURE An electrical switch having spaced stationary con- tacts and a contact carrier carrying a bridging contact in linear reciprocation relative to the stationary contacts, with the bridging contact biased toward the stationary contacts. The bridging contact has spaced opposite contacting ends forming a leading contact end and a trailing contact end for sliding move- ment between a bridging position where the contacting ends con- tact their respective stationary contacts, and a non bridging position where the leading contact end is out of engagement with its stationary contact. The bridging contact is rotatably hinged to the contact carrier and a projection is disposed be- tween the stationary contacts for engagement with the leading contact end for pivoting and lifting the leading contact end from its stationary contact in coaction with the hinged connec- tion with a quick break action during movement of the contact carrier to the non-bridging position. Each conductor wire connected to the switch is releas- ably secured therein by a spring-like retainer blade biased diagonally against the wire. Each retainer blade has a release arm for deactivating the retainer blade thus permitting easy withdrawal of the conductor wire. The release arm has a later- ally extending handle lug on its exteriorly exposed free end to provide a handle and also to provide for engagement with the switch housing to limit inward movement of the release arm. The inner end of the release arm is beveled to provide a plane- to-plane contact with the retainer blade for a positive contact therewith.
