Snap-Acting Switches





Open and close circuits in a snap. These switches actuate quickly to minimize arcing and prevent contacts from sticking. They’re often used to indicate that an appliance or enclosure door is open. You can also use them inside limit, pressure, and temperature switches.
Switches with a plunger actuator require a push to actuate, similar to a button.
Switches with a lever actuator have an arm that extends to give them a larger actuation area than switches with a plunger actuator.
Switches with a roller lever actuator combine the larger actuation area of a standard lever with a smooth gliding roller actuator. They minimize friction to limit wear and tear on your switch.
Plastic covers (sold separately) are compatible with switches with screw terminals. They fit over the bottom of the switch to prevent contact with live terminals.

Miniature Snap-Acting Switches



Smaller than standard size snap-acting switches, these fit in tight spaces. They open and close circuits quickly to minimize arcing and prevent contacts from sticking. They’re often used as door-open indicators on appliances and enclosures or as an internal component in limit, pressure, and temperature switches.

Subminiature Snap-Acting Switches




At least 25% smaller than our Miniature Snap-Acting Switches, these switches are often used to trigger actions from inside a vehicle’s door or an engine compartment. They open and close circuits faster than other switches, preventing contacts from sticking by reducing the time that they're near one another. They also minimize the chance of arcing, so electricity won’t jump across contacts.
Plunger actuator switches send a signal when the actuator is pushed directly downward. They have the smallest actuator of the actuators here, reducing the risk of accidental switching.
Lever actuator switches have a larger surface area than plunger actuator switches and can be pushed down by front-to-back movement, so they require less precision to activate.
Roller lever actuator switches allow parts to glide across the actuation surface with less friction than standard levers. This prevents wear and tear over time.
Simulated roller lever actuator switches have a curved arm that can be pressed down for actuation by forward, backward, and repeated back-and-forth movement.

Light-Touch Subminiature Snap-Acting Switches



Actuate these switches with a fraction of the force of other subminiature switches for increased responsiveness. They’re a good choice if you need reliable actuation even from a light touch. Among the smallest snap-acting switches we offer, they fit into the tiniest of spaces. To minimize arcing and prevent contacts from sticking, they open and close circuits quickly. They’re often used as door-open indicators on enclosures or as internal components in limit, pressure, and temperature switches.
Switches with a plunger actuator require a push to actuate.
Switches with a lever actuator have an arm that increases the size of the actuation surface.
Switches with a roller lever actuator allow parts to glide across the actuation surface with less friction than standard levers. This prevents wear and tear over time.

Subminiature Wet-Location Snap-Acting Switches



Built for tight spaces exposed to water, these switches have a housing that's less than 1" long and IP67 rated for protection from temporary submersion. They open and close circuits quickly to minimize arcing and prevent contacts from sticking. They’re often used as door-open indicators on appliances and enclosures or as internal components in limit, pressure, and temperature switches.

Low-Profile Limit Switches





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.
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.
Switches with a 4-pole micro M12 plug connect to cables with a socket (sold separately), allowing you to quickly connect and disconnect the switch.

Sealed Low-Profile Limit Switches



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.
Switches with a 4-pole micro M12 plug connect to cables with a socket (sold separately), allowing you to quickly connect and disconnect the switch.

Panel-Mount Low-Profile Limit Switches


Secure these switches into panel cutouts using mounting nuts. They have a slim body so they can also be stacked together or fit into tight spaces. 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 on conveyor systems and elevators. All are rated IP67 for protection from temporary submersion. They 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.

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.
