Through Mount Slotted Switch

ThroughMount Slotted Switch Mount switch through 5/8" hole in bulkhead or airframe.

Switch is SPDT so choose your own hookup method.

Originally used as a 120 / 240 voltage selector switch this unit is very clean and mounts almost flush.  You can scratch off the lettering and make the switch read 0 and 1 to indicate on and off as shown here.  Photo courtesy of Tim Kurreck.
