These parts are normally located in the hydraulic and diverter valve section of the Chaffoteaux boiler, they normally detect if a pump is running or if a diverter valve has moved position from heating to hot water.

Micro Switches are generally fitted to older boilers but can be found in some of the newer more energy efficient Chaffoteaux boilers. When the Micro Switch is operated an electrical signal is sent down to the printed circuit indicating that the Micro Switch has changed position.
