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.

Trigger actions in devices as small as phones and drones. The smallest snap-acting switches we offer, these switches fit into the tiniest of spaces and help keep weight to a minimum. Because snap-acting switches open and close circuits faster than other switches—reducing the time that contacts are near one another—they prevent contacts from sticking. 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 a small footprint, 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.

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.
