Choosing an Electrical Switch

22 mm Panel-Mount Build-Your-Own Metal Switches

Choose an actuator and contact block to make your own switch. All switches are rated NEMA 4, 13, and IP66 for protection from washdowns and oil/coolant spraying.

Key actuators are keyed alike, so they will all open with the same key.

Contact blocks with mounting latch accept additional contact blocks to control more circuits.

30 mm Panel-Mount Build-Your-Own Metal Switches

Choose an actuator and contact block to make your own switch. All switches are rated for protection from washdowns and oil/coolant spraying. NEMA 4X rated switches are also protected from corrosion. Use legend plates (not included) to label switches.

Key actuators are keyed alike, so they will all open with the same key.

Switch guards protect flush and projecting switches from accidental activation.

3/4" Panel-Mount Key Switches

With Screw Terminals

Prevent accidental activation and limit access—these switches require a key to turn circuits on or off.

Keyed alike switches all open with the same key.

16 mm Panel-Mount Key Switches

Limit access to sensitive equipment—these switches require a key to actuate. Rated NEMA 4, 13, and IP65, they're protected from washdowns and oil/coolant spraying. All are keyed alike, so they open with the same key.

Mounting wrenches (sold separately) make it easier to install switches in crowded panels.
