The Tecmark 3028 pressure switch is designed for compatible applications that use a single-pole normally open switch rated at 25 amps with a 1/8 inch barb connection. Pressure switches like this are useful because they help the system respond only when the expected pressure condition is present.

This replacement is especially useful when the original switch no longer reacts correctly, causes intermittent equipment response, or fails to sense pressure dependably. The barb-style connection also helps preserve the original hose-based installation format.

It is a practical service item when restoring pressure-sensitive switching is part of bringing a compatible heater or control system back into reliable operation.
