What it is

This is a microswitch supplied by Vaillant for use in the Turbomax range of combi boilers. It forms part of the appliance's electrical switching circuit, operating in response to the movement or pressure condition it is connected to. The part carries the reference 126262.

Signs this part needs replacing

  • The boiler does not respond to a heating or hot water demand.
  • The fan runs but the burner fails to ignite.
  • Operation becomes intermittent, with the appliance cutting in and out without a clear pattern.
  • The appliance locks out repeatedly and requires resetting.

Before you order

  • Confirm the boiler model against the fit list above.
  • Check the existing microswitch and note how it is mounted and wired before removal.
  • Compare the terminal arrangement and operating lever of the old part with the replacement.
  • Isolate the electrical supply to the appliance before starting any work.
