Flush-Mount 19 mm Panel-Mount Push-Button Switches
Because these switches mount flush against a panel, they're easy to clean and hard to damage. They're rated IP67 for protection from temporary submersion.

Low-Voltage 19 mm Panel-Mount Push-Button Switches
Operate low-voltage devices that require less than 48 volts, such as doorbells and buzzers. These switches have one input terminal and three output terminals to control up to three devices at once.

Single-Action Mechanically Operated Air Directional Control Valves
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 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.
