What to Do About Missing Breakaway Switch Pin if You Don't Know the Manufacturer

Question:

I am trying to figure out what replacement pin I need. The breakaway switch on on my 2005 Fleetwood Pioneer does not show a brand. All I can read on it is the warning label upon which it says PIN: 0045B. Visually it appears about like the #2010 but I am not sure. Can you help?

Not all pins are created equally but all breakaway switches are pretty much the same. Since we can't determine for sure which system you have I recommend replacing the whole switch with # HM20010.

The only thing in the switch are 2 metal contacts that are kept separated by the plastic pin. When the pin is pulled the contacts can touch and complete the circuit from the battery to the brakes. That is why you can use a different switch. It is a very basic system!
