Description
Latching design Single Pole Dual Throw air-activated switch rated at 20 Amp with through-panel mounting configuration. Features 1/8" spout air connection point and electrical terminations using 5/16" male quick connect tabs. Installation requires 5/8" panel cutout. Functions as the universal or standard substitute for the majority of single air-operated switches in spa applications. Operates as a Normally Open design that latches to Closed position when pressurized air reaches the internal diaphragm through connected Air Button tubing. Common failure modes include: electrical circuit opening preventing current flow to pump or blower when in closed position, or mechanical failure where air pressure fails to engage latching mechanism. When either failure occurs, replacement becomes necessary. Important distinction: a visually similar momentary (non-latching) variant exists as Part# htptbs304, utilized with Electric Stepper Switch assemblies. Safety Warning: Replacement procedures must only be performed with electrical supply completely disconnected from spa system and exclusively by qualified individuals with proper understanding of electrical hazards and safe repair practices.
