What is an air switch?

An air switch is a device that uses compressed air to operate an electrical switch. It typically consists of a pneumatic actuator that translates air pressure into mechanical force, which is used to open or close a switch contact. Air switches are commonly used in industrial and marine applications where electrical equipment needs to be controlled remotely or in hazardous environments. They offer a safer alternative to conventional electrical switches, as they do not require any electrical power to operate and are not susceptible to electrical arcing or sparking. Air switches can be designed for various pressure ranges, from low-pressure systems used in home spa systems to high-pressure systems used in heavy-duty industrial machinery.
