Make cheap fan control from old thermostat p.2

The casing is taken care of by simply moving the contacts one place to the right where the make contact pin should be.
Then the Break contact pin is unsoldered from the PCB...
...and refitted next door before being soldered to the PCB.
Meanwhile a mounting board is drawn up to mount the unit.
It's amazing just how untidy the bench gets at this stage in a little job!!
