It's a safety switch with the sole purpose of sending a signal to the circuit board to shut off the heater if low pressure (low water flow) occurs to protect the heater from overheating and burning out.\u003c\/p\u003e\n\u003cp\u003eIn a hot tub, pressure is an easy way to determine flow rates through the pipes, pump and heater. Some spas also use a Flow Sensor, in addition to (or instead of) the Pressure Switch, to be sure water is flowing properly for the heater to operate safely.\u003c\/p\u003e","brand":"Tecmark","offers":[{"title":"Default Title","offer_id":51401718497503,"sku":"wma1789520468557","price":22.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0812\/0893\/4623\/files\/tecmark-pressure-switch-for-hot-tub-3902_1.jpg?v=1789520496","url":"https:\/\/lightacademiaclad.shop\/products\/tecmark-pressure-switch-for-hot-tub-3902","provider":"My Store","version":"1.0","type":"link"}
