PresAirTrol Hergair Economy Flush Button Chrome B318CA

PresAirTrol-Hergair Economy Flush Button - hard air actuator.

Stem length is 1.78" with 1.76" button top diameter. The air spout diameter is 0.15 o.d. and this button is push-fit into hole made with 1 1/2" diameter.

Press fit into 1-1/2" pvc pipe, 1-1/2" hole size. Air button, chrome.

This air button is also called an actuator/bellow. The air switch receives the pulse of air from this air bellow/button actuator that is connected by tubing and converts it to an electrical signal within the spa pak for switching a device on either momentarily or latching.

Momentary means press=on and release=off. Latching or alternate means press=on, release=stay on, press again=off, release=stay off. Pushing the actuator/air button/bellow creates enough pressure to operate the air switch. There is complete electrical isolation with no voltage to be concerned with at the control button itself.
