Choosing an Electrical Switch

Plastic 22 mm Panel-Mount Lever Switches

These switches are rated IP66, IP69K, NEMA 3S, NEMA 4X, and NEMA 13, and are UL and C-UL Recognized Components. They include enough contact blocks to control the number of circuits listed. Contact blocks are rated IP20 and are UL and C-UL Listed.

Three-position switches are off in the center position.

Illuminated switches include a bulb. If wiring the switch and the bulb to the same circuit, the circuit voltage must not exceed bulb voltage.

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

Additional contact blocks (sold separately) can be added to control more circuits, or replace the included contact block.

16 mm Panel-Mount Lever Switches

Rated NEMA 4, 13, and IP65, they’re protected from washdowns and oil/coolant spraying.

Add a bulb (sold separately) to illuminate switches. If wiring the switch and the bulb to the same circuit, the circuit voltage must not exceed bulb voltage.

Use removal tools (sold separately) to replace bulbs and contact blocks.

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

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.
