Coil Winder Control Pedal - UK Vintage Radio Repair and Restoration Discussion Forum

Hi,

I recently acquired an Elmer cn101c coil winder:

The plug receptacle for the control pedal has 3 prongs and is circular ~ 10mm diameter and accepts a threaded round connector.

Does anyone have any idea why it would have a 3 way rather than a 2 way connector? I'm unable to find any details / circuit diagrams for the machine online, how might I go about making a replacement?

Thanks,

Jonathan.

Maybe they just used an available part so one pin is not connected to anything.
Have seen this on other things.

Reverse?
Some photos would be nice to view.
The one provided is very small.

It's just a simple on/off.

No idea why they used a 3-way connector - but I replaced one a few years ago and there are just 2 connections.

Hi, Thanks,

Have managed to obtain the correct foot switch now.
