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.

A simple automation solution that requires no programming, these valves are activated when an object, such as a box rolling on a conveyor, pushes the actuator. Also known as 3-way and 3/2 valves, they create one action, such as extending a cylinder. Valves direct airflow from the inlet to your equipment and exhaust return airflow to create motion. Return actuation is by spring, so they go back to their starting position as soon as the actuator is released. In the off position, they exhaust air pressure from the system, allowing equipment to reset so the action can be repeated.

Normally closed valves block airflow until actuated.

Valves that are both normally closed and normally open can be installed to block airflow, or allow air to flow until actuated.

Valves with a two-direction actuator are activated by objects from both sides.

Flow coefficient (Cv) is a measurement that indicates how much airflow can pass through a valve. When selecting between valves with the same port size, choose the valve with the higher flow coefficient to ensure it provides enough airflow to operate your system.

Often used to extend and then retract a cylinder at different speeds, these valves create two actions and have two exhaust ports, which allows you to control the speed of each action by attaching a flow control valve to each exhaust port. A simple automation solution that requires no programming, they activate when an object, such as a box rolling on a conveyor, pushes the actuator. They direct airflow from the inlet to your equipment and exhaust return airflow to create motion. Return actuation is by spring, so they go back to their original position as soon the actuator is released. Also known as 4-way and 5/2 valves.
