Abstract
A contactor providing for electrical contact in a welding torch includes a body member having first and second opposite sides, and adjacent pivot and head portions. The pivot portion has an outwardly curved contact surface on the second side providing a pivot point. The head portion also has a contact surface on the second side. The pivot portion has a shorter length between the first and second sides than the head portion. The contactor may be pivotally mounted in a torch connector body. At least one resilient member urges the contact surface of the pivot portion into engagement with an inner flange surface of the connector body, and biases the head portion into an opening in the torch connector body. The contact surface of the head portion is engageable with a torch neck inserted into the torch connector body, and provides an electrical connection between the torch body and neck.
