Panel-Mount Light-Touch Limit Switches

Our most sensitive limit switches, these switches actuate with the slightest push for a high degree of accuracy. They’re often used for determining manufacturing tolerances and detecting minute expansions and contractions. When an object pushes into the plunger actuator, it sends a signal to open or close a circuit. Install them in a standard panel cutout.
IP67 rated switches are protected from temporary submersion. They’re ideal for wet locations.

Panel-Mount Sealed Wet-Location Limit Switches

Sealed actuators prevent these switches from jamming, even when exposed to oil, sand, mud, or ice. 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. To actuate, they require a push, similar to a button. Rated IP68, they’re protected against dust and temporary submersion.
Switches with a stainless steel housing stand up better to wear and tear and corrosion better than switches with a zinc-plated steel housing.

Build-Your-Own Limit Switches
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.
Roller-plunger actuators open or close circuits when an object pushes against the roller, which moves the plunger. The roller 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.

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.
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.

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