there are actually 2 different switches among the TF years - or maybe among models - or maybe different assembly plants .... as billinwis sez, you may be able to mount it backwards, although it could be a stretch for the wires - the main difference is the terminal pins on one will face up and on the other face down when the actuator arm is the right way
part numbers for Cole Hersee:
#8487, pins down - #8486, pins up [also Standard #SLS43, most common I think]
