Save space in your setup—these switches double as handles on machines and equipment. Grab the handle and trigger the push-button to open the door and activate the switch in one motion. They’re often used on cages surrounding robotics.

Switches with status indicators alert you when a switch has been actuated.

Add a matching handle without a switch to keep door pulls uniform.

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

Switches with an on-on position designation alternate power between sets of terminals.

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

Keyed alike switches all open with the same key.

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.

Keyed alike switches all open with the same key.

Keyed differently switches each open with a unique key.

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.

Switches that control two circuits come with a contact block for each circuit.

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

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.

With a smaller footprint than other switch mats, these fit in confined spaces.

Combine an actuator and a switch to assemble the exact limit switch you need. These switches have the rapid-closing action of a snap-acting switch, but have a larger actuator for large objects. 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 for conveyor systems and elevators. Each actuator style is compatible with all housing styles and vice versa.

Switches with a polypropylene plastic housing are lighter in weight than metal switches.

Switches with a 4-pole micro M12 plug quickly connect and disconnect from your setup. Use cables (sold separately) to wire your switch connection to your setup.

IP65 switches protect against dust and splashing water. IP67 switches protect against dust and temporary submersion.

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.

Plunger actuators open or close circuits when objects push against them.

Roller-plunger actuators open or close circuits when an object pushes against the roller, which moves the plunger. The roller moves parallel to the mounting direction, so it helps push the plunger even if the force isn’t straight on. The roller also reduces friction during actuation which prevents wear and tear over time.

Cross roller plunger actuators open or close circuits when an object pushes against the roller, which moves the plunger. The roller moves perpendicular to the mounting direction and reduces friction during actuation which prevents wear and tear over time.

Roller-lever actuators open or close circuits when material moves across the switch. The roller reduces friction during actuation which prevents wear and tear over time.

Wobble stick actuators open or close circuits when an object hits the flexible arm. The arm has a 360° range of motion, so it can be actuated from any direction. This means that if there’s a jam, these switches are less likely to break than switches that are aligned to a specific direction.

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.

Switches with a plunger actuator require a push to actuate, similar to a button.

Switches with a roller plunger or cross roller plunger actuator have a roller that moves when an object pushes the actuator. This reduces friction during actuation to limit wear and tear on your switch. On cross roller plungers, the roller moves perpendicular to the mounting direction.

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.

Switches with a plunger actuator require a push to activate, similar to a button.

Switches with a roller plunger actuator have a roller that moves parallel to the mounting direction when an object pushes the actuator. This reduces friction during actuation to limit wear and tear.

Switches with a roller lever actuator use a lever with a roller at the end to activate. This allows parts to glide across the actuation surface with minimal friction, limiting wear and tear.

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.

All switches require an actuator key, but not all include one—check whether you need to pick out a separate actuator key. For some switch styles, you can also select the mounting orientation of the key. Flexible keys pivot at least 15°, making them easier to align with switches during installation.

Style A-G switches have positive-force, normally closed contacts that will open a circuit when the switch is actuated even if a spring fails or the contacts stick.

IP67 rated switches protect against temporary submersion.
