Choosing and fitting
When replacing a door switch of this type, the key parameters are the electrical rating (voltage and current for the control circuit) and the physical mounting and actuator travel. The switch must match the original in actuation force and position so that it closes correctly when the door is shut and opens positively when opened. Compact variants are often used where space around the door hinge is limited. During replacement, verify wiring is correct, avoid overtightening, and test the switching function with a multimeter before closing the boiler.
