I'm reading it takes a 53 [12v version of the 51]. I dont think thats right, it swallows that bulb. Anyone know what the right bulb would be?

If a longer bulb is needed, then perhaps a #1488 or a #756 might work. The #53 is, I think, about 1/2 inch long and the others are about twice as long. The 1488 doesn't last long but is easy to find. The 756 seems to last "forever" but probably will only be found at a specialty store. All of them are (should be) less than $1. Edited by elawson - 20 May 2021 at 9:55pm |

I still cant figure out how the light bulb sits in this switch. There are no notches for it to twist and sit in like a 1156 for example.

Is this what you're working with?

That is correct. Only thing I don't have is the knob.

Can you get a picture of the inside of the socket? And, what is the approximate diameter of the socket? I can dig through some catalogs and I might get lucky. Eric

I will. It's just a brass cylinder with a contact at the bottom. Kinda wondering if the knob has something to do with holding it in.

I suppose that's possible the knob holds the bulb in place, but I'd be surprised. Oftentimes the socket has L shaped groves instead of L shaped slots and the groves are hard to see. And, sometimes the fiber washer that is in the bottom of the socket to hold the center contact will move up enough that it will hide most of the slots/groves. If the groves/slots aren't there, then the socket would need to be large enough to fit the pins on the bulb base and this would not do a good job at keeping the bulb from wobbling in the socket....even if the bulb were held in by the knob.

Pictures help a lot. I've not seen one of these in person but since it's so small and has a knob over the bulb, I wonder if the bulb just has a friction fit, i.e. if it has bayonets like a typical bulb it would just make contact with the socket and the bottom of the bulb touches the base and completes the circuit.

There is this: https://www.thecj2apage.com/forums/heater-switch-refurbish_topic43220.html
I'm going to have to take mine apart again. I've got to be missing something.

I remember seeing that thread. More detail on the inner sleeve would be helpful....I can almost convince myself I see an indentation for the bayonets....

Me too but I didn't see them on mine. I'll take it apart again later. Unless something it blocking the bottom from compressing and they are hidden.

The barrel is perfectly smooth. This is a 53 bulb which I am told is what it takes, obviously it doesnt.

You may have a model that didn’t light up. The one I have here has the spots stamped into the barrel and the spring loaded pin on the fiber board. But when I took it apart it didn’t have a bulb and it has a solid black knob that light doesn’t pass through, so the bulb would have been pointless.

This does light up. See the contact in the first picture? I'm to the point now where I really dont care but I do care that I cant figure it out. :)

Hmm. I wonder if they used a flange based bulb (looks like a regular flashlight bulb), but I'm not sure how it would get held in place as the flange is nearest the glass. A regular flashlight bulb typically doesn't have a long lifespan and are very bright, so that likely wouldn't work well. The make a flange base bulb (midget flange base, aka SX6S) with the flange near the contact (#330 bulb), but the largest diameter base in that style is just over 1/4 inch...your 53 bulb base is around 3/8 inch...so this is going backwards. Maybe "48" is right and the system looks like it would hold a bulb, but doesn't......

I'm still thinking. The BA15S lamp base is about 9/16 in diameter. If the bayonet lugs are close enough to the contact, I suppose the bulb could be inserted like you have in your picture, but with the lugs engaging the two slots...and then things put back together.. A #5007 bulb is what I'm thinking about, but at 5 watts, it seems a bit bright/hot but, I guess if the resistor is getting so hot, then the extra heat from the bulb won't matter much.

There are no slots. It would have to be a smooth bulb base. That slot isnt for the bulb I dont think. I think it was to do with the friction fit of the knob.
