ABSTRACT:
A trigger operated tool handle electrical switch in which each conductor wire connected to the switch is releasably 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 laterally 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.
