Shaft and Panel Seal

All switches are provided with a shaft and

panel seal.

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.

Custom encoders with options such as custom

code output, 1/4” shaft diameter, factory set

stops and longer shaft terminal lengths are
