The rotating cam limit switch includes a hub, a position screw arm, a position screw, a position wheel, a retractable cam, a dwell wheel, a dwell screw, a dwell screw arm, a spring wave washer and a locking ring. The hub is to be mounted on a rotating shaft which is to activate a non-rotating switch assembly. Near a first axial end, an integral position screw arm and position flange extend radially from the integral hub. The position screw arm carries a position screw, which is snap fitted onto the arm, which operatively engages the position wheel rotatably mounted on the hub next to the position screw arm. The dwell wheel is also rotatably mounted with respect to the hub. The dwell wheel is operatively engaged by the dwell screw carried by the dwell screw arm integrally formed with a dwell flange. The dwell screw arm is fixed to the hub by hub a anti-rotation device. The wave washer and the locking ring, mounted near a second axial end of the hub, compress the rotating components together. A cam chamber defined by the position and dwell wheels receives a retracted portion of the flexible elongate retractable cam. The dwell wheel operatively engages the cam to vary the length of the exposed surface of the cam. The exposed surface of the cam activates the switch of the switch assembly. Differing indicia of degree position and dwell are marked about the circumference of the position and dwell wheels.

Rotating retractable cam limit switch

The rotating cam limit switch includes a hub, a position screw area, a position screw, a position wheel, a retractable cam, a dwell wheel, a dwell screw, a dwell screw arm, a spring wave washer and a locking ring. The hub is to be mounted on a rotating shaft which is to activate a non-rotating switch assembly. Near a first axial end, an integral position screw arm and position flange extend radially from the integral hub. The position screw arm carries a position screw, which is snap fitted onto the arm, which operatively engages the position wheel rotatably mounted on the hub next to the position screw arm. The dwell wheel is rotatably mounted on the position wheel. The dwell wheel is operatively engaged by the dwell screw carried by the dwell screw arm integrally formed with a dwell flange. The dwell screw arm is rotatable on the hub but fixed to the position wheel. The wave washer and the locking ring, mounted near a second axial end of the hub, compress the rotating components together. A cam chamber defined by the position and dwell wheels receives a retracted portion of the flexible elongate retractable cam. The dwell wheel operatively engages the cam to vary the length of the exposed surface of the cam. The exposed surface of the cam activates the switch of the switch assembly. Differing indicia of degree position and dwell are marked about the circumference of the position and dwell wheels.

Rotating cam limit switch

A mounting assembly for securing a control relay in sound isolation to the vehicle chassis to prevent the energizing and de-energizing noise of the relay from being transmitted through the vehicle chassis. The assembly includes a pair of absorbing members which receive a mounting bracket attached to the vehicle chassis and which are seated within a retaining sleeve of the relay housing. The absorbing members prevent contact between the mounting bracket and the relay housing and absorb the noise of the relay to prevent transmission to the vehicle chassis. An abutment flange and a retaining clip on the mounting bracket disposed on opposite sides of the retaining sleeve cooperate with a dividing wall in the retaining sleeve to prevent axial movement of the mounting bracket and absorber members relative to the control relay.
