Choosing an Electrical Switch

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.

Switch guards protect flush and projecting switches from accidental activation.

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

Choose an actuator and contact block to make your own switch. Actuators are rated NEMA 3S, 4X and 13 for protection from dust, outdoor environments, corrosion, oil, and washdowns. Use legend plates (not included) to label switches. BACO Controls switches are only compatible with BACO manufactured legend plates.

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

Mounting tools make it easier to install switches in crowded panels.
