This pressure switch is installed on some Watkins spa heaters, themselves installed on spas from the brands Hot Spring, Caldera, Solana, Tiger River and Hot Spot.
The pressure switch is among the most important pieces of safety equipment found in your spa system. It monitors the water flowing through the heater and cuts off heating if the flow rate is insufficient to prevent overheating.
It comes with a 21 cm cable to connect to the pressure switch to the spa control system (see the photo).
