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 roller plunger or cross roller plunger actuator have a roller that moves when an object pushes the actuator. This reduces friction to limit wear and tear on your switch. On cross roller plungers, the roller moves perpendicular to the housing.
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.
Switches with a wobble stick actuator have a flexible arm that can actuate from any direction.
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.

Enclosed Snap-Acting Switches
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.

Enclosed Wet-Location Snap-Acting Switches
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.

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.

Corrosion-Resistant Washdown Limit Switches
Rated NEMA 6P, 13, and IP67, these switches are protected from corrosion, oil/coolant spraying, washdowns, and 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 bin filling operations.
Switches with wire leads are rated NEMA 3S and IP69K and protected from rain, snow and sleet, and from high temperature, high pressure jets of water.

Low-Profile Wet-Location 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. They’re often used on conveyor systems and elevators.
Switches with powder-coated zinc and plastic housings are rated NEMA 4 and 13 for protection from washdowns and oil/coolant spraying.

Sealed Wet-Location Limit Switches
Sealed actuators prevent these switches from jamming, even when exposed to sand, mud, or dirt. They're rated IP67 for temporary submersion. They have a slim design and can be stacked together or fit into narrow spaces. 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.
Switches with powder-coated zinc and plastic housings are rated NEMA 4 and 13 for protection from washdowns and oil/coolant spraying.

Manual-Reset Safety Limit Switches
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.
