Operate low-voltage devices that require less than 48 volts, such as doorbells and buzzers. These switches have one input terminal and three output terminals to control up to three devices at once.

Maximize space in a panel—these switches are smaller than most standard rocker switches.

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

Prevent accidental activation and limit access—these switches require a key to turn circuits on or off. All fit into a standard panel cutout.

Stack these slim switches together, or fit them 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. These switches have the rapid-closing action of a snap-acting switch, but have a larger actuator for large objects. They’re often used on conveyor systems and elevators.

A sealed actuator prevents these switches from jamming, even when exposed to sand, mud, or dirt. They're also rated IP67 for temporary submersion. With a slim design, you can stack them or fit them in tight spaces. When an object in motion comes into contact with the actuator, it sends a signal to open or close a circuit. These switches have the rapid-closing action of a snap-acting switch, but with a larger actuator. This makes them a good choice for use with large objects. For instance, a box on a conveyor runs into the switch, stopping the conveyor.

Also known as interlock switches, these ensure the safety of personnel by automatically shutting off power to machinery when an access door opens. Mount the switch to the door frame and mount a key to the door so that the key is inserted into the switch when the door is closed. When the door opens, the key is removed from the switch and the machine shuts down. They’re often used with machine guards for large robots.

Make or break an electrical circuit. These contact blocks mount to manual switches and transmit an electrical signal when the switch actuator is engaged. You can stack multiple blocks, so a single switch can control several circuits. This is helpful in setups that require multiple systems to turn on or off at the same time. For example, the switch on a conveyor line could turn off the conveyor and turn on a diverter and alarm.

Shorter and thinner than other safety limit switches, these are sized to fit tight spaces. They protect machinery and ensure the safety of personnel. Positive-force contacts open the circuit when actuated, even if a spring fails or the contacts stick. 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. All are NEMA and IP rated for protection from washdowns.

Designed for use near ignitable gases, fibers, and dust, these switches have a housing that seals in anything that could ignite flammable material. You’ll know they’re safe because they’re NEC Class 1, Division 2 Groups A-D and NEC Zone 1 Groups IIC-IIA certified for hazardous locations. These switches require a key to turn circuits on or off, preventing accidental actuation and limiting access to sensitive equipment. Since they’re keyed alike, all open with the same key. Install them in a standard panel cutout.

Rated NEMA 4 or IP66, these switches are protected from washdowns. They require a key to turn circuits on or off, limiting access to sensitive equipment. All fit into a standard panel cutout.

Maximize space in a panel with these miniature switches. They require a key to turn circuits on or off, limiting access to sensitive equipment. All are keyed alike, so they open with the same key.
