Installation Considerations
Lever Actuators
For limit switches with lever actuators, the actuating force should be applied as nearly perpendicular to the lever as practical and perpendicular
to the shaft axis about which the lever rotates.

Dwelling Requirements
Where relatively fast motions are involved, the cams
should be so designed that the limit switch will be held
operated long enough to operate relays, valves, etc.

Overtravel limitations
Operating mechanisms for limit switches should be so designed that, under any
operating or emergency conditions, the limit switch is not operated beyond its
overtravel limit position. A limit switch should not be used as a mechanical stop.
