djncarpediem Posted December 20, 2021 Share Posted December 20, 2021 Does anyone know the full name of this company? It looks like CS Manufacturing? I'm guessing that stands for something. And are these called 2 pin connectors or something else? Thanks Link to comment Share on other sites More sharing options...
8E45E Posted December 21, 2021 Share Posted December 21, 2021 (edited) Chicago Specialty. They manufactured plumbing and hot water heating parts. Most likely a knob from a manual bleeder valve for purging air out of a boiler system in a building. http://progress-is-fine.blogspot.com/2013/07/vanished-tool-makers-chicago-specialty.html Craig Edited December 21, 2021 by 8E45E (see edit history) Link to comment Share on other sites More sharing options...
Bloo Posted December 21, 2021 Share Posted December 21, 2021 I don't know CS, but I'd say that goes in the back of a headlight. 1 1 Link to comment Share on other sites More sharing options...
hddennis Posted December 21, 2021 Share Posted December 21, 2021 Curious to see the front of this connector. Can't help with who C S is but I'm pretty sure this is a headlight connector for a dual filament bulb judging by the two brass set screws. Shape wise it's identical to my 1917 Maxwell headlight connector which is only a single filament bulb. Howard Dennis 1 Link to comment Share on other sites More sharing options...

To maintain a comfortable temperature inside the building its designed to heat when the outside temperature is below zero, like it is here today. Learn more about heat loss calculation here: http://www.sensiblehouse.org/nrg_heatloss.htm#:~:text=The general heat loss formula,might not be quite the Another reason for heating already hot-to-the-touch water in a different application is to satisfy NSF compliance for sanitation in the Food & Drink industry when it comes to reusing kitchen equipment: http://alliedboilers.com/products/electric-booster-water-heater/ NSF standards are 180°F vs. residential water heater storage tank at 140°F. Don't get me started on STEAM applications!!! Craig Edited December 21, 2021 by 8E45E (see edit history) Link to comment Share on other sites More sharing options...
djncarpediem Posted December 23, 2021 Author Share Posted December 23, 2021 It's definitely an electrical component. I was thinking it was a 2 pin headlight connector too. I just was wondering if there was maybe a technical, industry standard, name for it. And I was curious who the manufacturer is. Thanks for the discussion everyone.

CarlLaFong Posted December 23, 2021 Share Posted December 23, 2021 It's an on/off switch for an interocitor Link to comment Share on other sites More sharing options...
