How A Pneumatic Push Button Switch Operates

A pneumatic push button switch or a pneumatic push button valve can be used to control many different types of equipment, system components, and devices. As the name implies, they are manually controlled by the operator or user depressing a button that is located on the top side of the switch or valve.

There is a range of different sizes and configurations in a pneumatic push button switch or pneumatic push button valve. They are generally smaller components in a system, and they are often designed to mount into a panel. However, there are also non-panel mount push button switches and valves used, commonly on dental equipment where the button acts as the controller for the system.

There are also large push button switches that are used for any type of emergency shutoff systems or even for applications such as an elevator or large equipment control. As they are designed to serve an on or off function, they can be simple in design to last for years of use with no maintenance, even if only used extremely infrequently.

How They Work

A pneumatic push button switch or a pneumatic push button valve can be designed to be Normally Open (NO) or Normally Closed (NC). When the button is pressed from the normally open or closed state, the air flow through the valve is either allowed to flow through or stopped.

Pressing the button again returns the valve or switch to the normal position. The various configurations of the push button switch or valve allow for two or three way flow with different options of side ports. It is also possible to have a swivel on the bottom of the valves, allowing for multidirectional positioning of the body of the valve to accommodate different types of equipment and systems.
