    just a switch C NO & NC you would get continuity between C NO if there is 1bar in the boiler, but if there is 1 bar in the blr an continuity between C NC then its fooked

    this is a standsrd Low wtr pressure switch.

    Check the perameters in the pcb u might find it thinks it has pressure switch rather than sensor happens all the time
