I have an older Sears hassock fan that I have been saving, and now would like to use in my new sun room. The problem is that the control knob has been lost. The stem has two flat sides and a groove through the end, and so far the only replacement knob I've been able to find at a local electronics store is for round stems.
This is probably a long shot, but any ideas on where to find a replacement knob? I know I could probably use pliers to turn it on, but I'd rather have a more reliable method. (Visions of something getting sucked into the fan and wanting to turn it off in a hurry!) I'm hoping maybe I'll be lucky and this is some sort of a standard type of knob.
