Pressure Switch Tecmark (All Spas)


Mounted to your heater assembly, pressure switches convert a pressure signal to an electrical output. In response to a change in pressure, movement of an elastomeric diaphragm opens or closes an electrical circuit based on a predetermined pressure set point. Or in short, they ensure there is water flowing through the heater before allowing power to the element.

All of our pressure switches come pre-calibrated for easy installation.
