Sensors & Switches

Sensors and switches are the monitoring and safety components wired into your spa's control system, detecting water temperature, flow, pressure, and air input. A faulty sensor or switch can cause your hot tub to display error codes, shut down heating, or behave erratically. Spa Guy Parts carries a comprehensive range of sensors and switches including temperature sensors, hi-limit sensors, air switches, pressure switches, and flow switches.
