ABSTRACT:
A cylindrical contact carrier (4) is journaled for rotational movement about an axis extending in the direction of linear movement of a depressible trigger operator (2). Spiral grooves (4d) formed in the carrier (4) cooperably receive cam elements (10g) which are disposed in fixed planes with respect to the axis of rotation and depression of the trigger operator (2) effects relative linear movement of the cam elements (10g) with respect to the spiral grooves (4d) to cause rotation of the carrier (4) for moving contacts (18) positioned on the carrier (4) into and out of engagement with stationary contacts (22) disposed around the periphery of the carrier (4).
