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.

Ultra-Miniature Snap-Acting Switches
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.
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.
