For 1/4" Panel Cutout Dia.

For 13/32" Panel Cutout Dia.

Control multiple devices with one switch. Turn the shaft to change switch positions. Each position closes a set of contacts per circuit, so you can select between multiple devices on one or more circuits.

Switches for 13/32" panel cutout diameter require a knob.
