How to replace micro switch in two port valve?

Actually possible to strip down while connected to wiring centre. (Mains isolated, naturally).
Had same stuck on issue and over-pumping into header tank at the in-Laws.
A short term solution was to clean up the mechanism to free up the microswitch button which was being held in by sticky grease (IPA - not the beer - to degrease) then some silicone grease to lubricate. The switch contacts can arc and weld shut due to the inductive pump motors, though.
The microswitches are under £4 delivered on eBay... or £6 for two. A fraction of the cost of a new head and the satisfaction of a DIY fix.
shows exactly how to do it!!! Three wires and soldered as I thought.
WD40 comes in many variants... Some allegedly do harm to some plastics.

That seems easier than replacing the whole head, seems the best way forward. Thanks.
