Re: [PLUG] OT: need SPST-NC lever switch

Try Staley Electric in Conshohocken if this is an electrical part you need. He is my cousin. That won't cut you any price break but he has helped me out on the network end. They are on Fayette street. He used to have a web site but I am coming up with a company based in Arkansas and that isn't him. He has been in Conshy for over 50 years

This is certainly my day for emailing this list.  My condensation pump limit/float switch just fried and I'm hoping someone with more of a background in industrial parts can help me out.  I've worked around the problem but I don't want to let it go more than a few days if I can help it.

The pump is a Beckett CB151UL and the dead part is a:
        Hoppy HP-S1004 5A 250V #110 tab SPST-NC [1]

As noted it is normally closed, with the lever flush against the case, and the spring pulling it closed.  The float hooks around the lever and when the water is low pulls the switch open.  When the float rises the lever closes and runs the pump until the float drops and opens it again.

The switch housing is 20cm x 10cm  and the lever protrudes 21cm out from the side.

Obligatory ASCII-art (slightly smaller than scale):

                    ||| < Float arm, water high, pump on

I hate to have to replace a $50 pump for lack of a $3 part, but I can't find anything that looks like it'll work.  I've spent a bunch of time on Google, Grainger, Mouser, Digi-Key, and Amazon and I'm coming up empty.  I can't find the Hoppy part at all, except [1], and I'm not finding a compatible replacement otherwise.  I'm sure it's out there, I'm just not well enough versed in industrial supply to find it.  I also only want 2-4 of them (I have 2 of that pump and I know that other crappy switch will go sooner or later).

Can anyone help me out with some clues and/or a local (Collegeville, KoP, Pottstown?) place that might stock something like this?
