What it is

The MICROSWITCH ASSEMBLY is a Grant switch component intended for use in the manufacturer's oil-fired combi boiler range. It forms part of the boiler's electrical control circuit, where the microswitch responds to mechanical actuation to signal a demand or change of state to the control system. The part is supplied under Grant part number MPCBS41.

Signs this part needs replacing

  • The boiler does not respond when there is a call for heat.
  • Operation is intermittent, with the boiler cutting in and out without a consistent pattern.
  • The switch fails to actuate or return correctly when the mechanism is operated.
  • Electrical continuity through the switch is absent or unstable when tested.

Before you order

  • Confirm the boiler model and variant against the fit list above.
  • Check the existing switch against part number MPCBS41 before ordering.
  • Isolate the electrical supply to the appliance before inspection or replacement.
  • Verify that the fault lies with the switch rather than the associated wiring, actuator or control board.
