1. A microswitch based position sensor for a motorised valve comprising:
a printed circuit board, PCB, based connector for connecting at least one wire to at least one solder pin, the PCB having at least one first through hole and at least one second through hole;
at least one microswitch having at least one solder pin, wherein each said solder pin is provided through a respective one of the first through holes so as to electrically connect to the PCB;
at least one wire passing through a slot on the PCB and connected to a respective one of the second through holes so as to electrically connect to the PCB; wherein
the at least one wire passes through the slot with an interference fit;
wherein the at least one wire is provided with a stress relief portion proximate the at least one second through hole, between the at least one second through hole and the slot;
further comprising a cover provided around the PCB, slot and stress relieving portion of the wires configured to make the connection between the PCB and wires rigid; and
wherein the at least one wire is connected to the respective one of the second through holes on a first side of the PCB, and the cover is connected to the PCB on an opposed side.
