1951 ignition switch Source, please

:confused:Folks, to start my '51 Roadmaster Rivera I sometimes have to wiggle the ignition key. Probably need a new switch. Where to find a NOS or rebuilt? Thanks in advance for your assistance.

Explain "wiggle the ignition key". Do you have to wiggle to get it to turn or wiggle to make contact?

A few months ago, maybe a year now, I had to wiggle the switch on my '60 to make contact. I found a new one, NOS, on EBay. I don't see it here on my desk so it must be in the glove box of the car. I think I've only had to wiggle it twice since the new switch got here.

Got to thinking, a thief would have to know about the pedal start AND be aware enough to wiggle it. Maybe this winter.

I have to move it or "wiggle it" (the key) to get the car to start. when engaging the starter. I just cranks without starting then if I move the switch (wiggle the key) it starts. Seems to me that the electrical contacts are/might be defective. Makes me wonder if it is the contacts then would the engine cut out while on the road, causing some further difficulties. I have not tested that idea, however.

How many wire terminals are on the back of the switch? It is hard to tell from the wiring diagram: http://www.teambuick.com/reference/years/51/51_wiring_50_70.php
