Enclosures protect these snap-acting switches from the environment. 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.

Switches with a plunger actuator require a push to actuate.

Switches with a roller plunger, cross roller plunger, or roller lever actuator allow parts to glide across the actuation surface with less friction than standard plungers or levers. This prevents wear and tear over time.

Switches with a lever actuator have an arm that increases the size of the actuation surface.

Rated NEMA 4 and IP66, these enclosed switches have a sealed actuator for protection from washdowns. They open and close circuits quickly to minimize arcing and prevent contacts from sticking.

Rated IP67, these switches have an enclosure that shields their interior during temporary submersion. They open and close circuits in a snap—their quick actuation limits arcing and keeps contacts from sticking. These switches are often used to indicate an open appliance or enclosure door. 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 roller plunger actuator have a roller that moves parallel to the body length when an object pushes the actuator. This reduces friction to limit wear and tear on your switch.

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.

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.

Switches with plastic or powder-coated zinc housings are rated NEMA 4 and 13 for protection from washdowns and oil/coolant spraying.

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.

Prevent equipment from automatically restarting—these switches must be manually reset each time they're actuated. Pull the knob to reset. Positive-force contacts open the circuit when actuated, even if a spring fails or the contacts stick. These switches 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.

Rated IP67, these switches seal out water if they’re washed down or briefly submersed.

Styles B and C have a roller lever actuator that allows parts to glide across the actuation surface with minimal friction. Style C have an actuator that allows you to adjust its height, making it easier to align the switch with the target during installation.
