[Healeys] OD Switch

'Perfect' is in the eye of the Healey driver: My BN2 activates the O/D 
in the up position; my BJ8--with both a dash switch and a (DWM) knob 
switch--activates the O/D with the switch down. Yes, I get confused when 
I 'switch' (heh) from car to car. The BJ8 switches are wired in 
parallel, throw either switch down and the O/D activates, but both 
switches have to be up to deactivate it.

The O/D switch is an 'SPST'--Single Pole, Single Throw--switch, the 
simplest of all manual electrical switches. Like Bob H. suggested, the 
only way this happened is the switch got reversed in the knob. The DWM 
knob has a small set screw and a 'cap,' I haven't tried, but I presume 
the switch could be replaced if necessary.

It works perfectly, just up side down. Any ideas on how this could have happened and how to cure it?  The wiring in the car was not changed nor has the solenoid.
