ABSTRACT:
A welding gun having a switch comprising two spaced apart coaxial conducting springs which act as switch contacts for completing a circuit to initiate a welding process. A coaxial flexible wall in the handle of the welding gun surrounds the two springs such that, when a welding machine operator depresses the flexible wall, the two springs make electrical contact to complete the circuit. When the flexible wall is released, the springs return to their original positions, thereby interrupting the electrical circuit.
