Abstract
A pneumatic operator for an air switch is provided. The operator is used to deliver at pulse of relatively high pressure air to an air switch, such as an air switch which would be commonly used in a spa bath or spa pool installation to operate a pump. The operator has a cylindrical plunger within which is provided a stationary body and an O-ring on an outer surface of the stationary body provides a seal between the stationary body and the plunger. Depression of the plunger expels the air from the apparatus to operate an air switch. When the plunger is returning to its original position, the seal can move to allow air from the surrounding environment to enter the space between the plunger and the stationary body.
