Abstract
A modular selector switch operator includes a housing and a cylinder rotationally mounted in the housing. The cylinder has a radially extending follower and a circumferential cam track. A knob extends forwardly of the housing and is operatively connected to the cylinder for rotating the cylinder. A pusher is received in the housing and has a follower pin riding in the cam track to convert rotational movement of the cylinder to linear movement of the pusher for actuating an electrical switch, in use. An indexing cam ring is concentrically mounted to the cylinder in the housing in one of two orientations with the cylinder follower engaging the cam ring. A first orientation provides a maintained actuation position relative to a neutral position. A second orientation provides a momentary actuation position relative to the neutral position.

A modular selector switch operator including:
- a housing;
- a cylinder rotationally mounted in the housing and having a radially extending follower and a circumferential cam track;
- a knob extending forwardly of the housing and operatively connected to the cylinder for rotating the cylinder;
- a pusher received in the housing and having a follower pin riding in the cam track to convert rotational movement of the cylinder to linear movement of the pusher, the pusher for actuating an electrical switch, in use;
- and
- an indexing cam ring concentrically mounted to the cylinder in the housing in one of two orientations with the cylinder follower engaging the cam ring, a first orientation providing a maintained actuation position relative to a neutral position and a second orientation providing a momentary actuation position relative to the neutral position.
A selector switch operator including:
- a one-piece tubular barrel housing;
- a cylinder rotationally mounted in the housing and having a radially extending follower and a circumferential cam track;
- a knob extending forwardly of the housing and operatively connected to the cylinder for rotating the cylinder;
- a pusher received in the housing and having a follower pin riding in the cam track to convert rotational movement of the cylinder to linear movement of the pusher, the pusher for actuating an electrical switch, in use;
- and
- a ring gasket surrounding the knob and received in the barrel housing, the ring gasket including a wiper seal engaging an inner wall of the housing to prevent water entry into the housing.
