I think my headlight switch is broken, the shaft won’t stay in. How can I get this shaft seated?

This is a frequently submitted question with a very simple solution.   We have found that some of our switches need a slight pressure applied to the middle of the switch to get the headlight shaft to seat.   If you can hold the switch with the metal side down, support the ends of the switch and giving the whole assembly a slight upward pressure in the middle the shaft should slide right in.
