Micro Switches are normally located in the hydraulic and diverter valve section of the boiler, they usually detect if a pump is running or if a diverter valve has moved position from heating to hot water, this then sends a signal to the printed circuit board, letting it know that more hot water is needed. Micro Switches are generally fitted to older boilers but can be found in some of the newer more energy efficient ***** boilers.
