Combi Boiler Flow Switch 3/4 – 2 Wire

With a 3/4 connection size, this flow switch is used to detect water flow in combi boilers and similar domestic hot water systems. When water flow starts, it generates an electrical signal that controls the boiler’s ignition and operating process. Its 2-wire design provides easy connection and stable operation.
