Choosing an Electrical Switch
More
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.
Round illuminated push-button actuators require a contact block with a bulb holder. If wiring the switch and the bulb to the same circuit, the circuit voltage must not exceed bulb voltage. Oval illuminated push-button actuators only require a contact block.
Key actuators are keyed alike, so they will all open with the same key.
IP67 rated actuators are protected from dust and temporary submersion.
Padlockable covers prevent unauthorized use.
Contact blocks with mounting latch accept additional contact blocks to control more circuits.
Mounting tools make it easier to install switches in crowded panels.

Choose an actuator and contact block to make your own switch. All switches are rated NEMA 4 and 13.
Flush and projecting switches are rated IP66.
Mushroom switches are rated IP65.
Illuminated push-button actuators require a contact block with a bulb holder. For yellow actuators, use a white bulb. If wiring the switch and the bulb to the same circuit, the circuit voltage must not exceed bulb voltage.
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.

16 mm Panel-Mount Build-Your-Own Plastic Switches
Choose an actuator and contact block to make your own switch. All switches are rated NEMA 4, 13, and IP65 for protection from washdowns and oil/coolant spraying.
Actuators spring back (momentary), but can be wired to stay switched (maintained).
Add a bulb to illuminate actuators. If wiring the switch and the bulb to the same circuit, the circuit voltage must not exceed bulb voltage.
Use removal tools to replace bulbs, lenses, and contact blocks.
Mounting wrenches make it easier to install switches in crowded panels.

Ultra-Precision Limit Switches

These switches actuate with the slightest push for a high degree of accuracy. They’re often used for determining manufacturing tolerances and detecting minute expansions and contractions.

Panel-Mount Sealed Wet-Location Limit Switches

Sealed actuators prevent these switches from jamming, even when exposed to oil, sand, mud, or ice. They send a signal to your circuit when an object hits the actuator—for instance, a box on a conveyor runs into the switch, stopping the conveyor. They open and close circuits as fast as snap-acting switches, but they have a bigger actuator for large objects. To actuate, they require a push, similar to a button. Rated IP68, they’re protected against dust and temporary submersion.
Switches with a stainless steel housing stand up better to wear and tear and corrosion better than switches with a zinc-plated steel housing.

Ultra-Precision Wet-Location Limit Switches

Panel-Mount Low-Profile Wet-Location Limit Switches


Secure these switches into panels using mounting nuts. They have a slim body so they can also be stacked together or fit into tight spaces. They're rated IP67 for protection from temporary submersion. When an object in motion comes into contact with the actuator, it sends a signal to open or close a circuit. They’re often used on conveyor systems and elevators. All have a 4-pole micro M12 plug that connects to cables with a socket (sold separately), allowing you to quickly connect and disconnect the switch.
