Options
Adjustable Stop Switches
The switch may have continuous rotation, or
be adjusted to limit the rotation. The panel
seal ring can be removed to expose the stop
pin holes on the front of the switch. Two stop
pins and panel seal o-ring are supplied with
the switch. One or both may be used to limit
the rotation as desired.
