*Double-Pole/Single-Pole Note:
Back in the early 1900's a Double-Pole Switch had the following definition:
A switch which simultaneously breaks the circuit of both positive and negative leads.
This was to reduce the "spark", that was prevalent in switches at the time. This Double-Pole Heater switch does not require 2 circuit lines into the switch, instead, only 1 circuit line is required, like a Single-Pole switch today.
Dimensions: LARGE Switch: 3 1/2" high, 3 5/8" bottom diameter
Condition:
Excellent working condition. Tested.
I sell a good number of antique/vintage switches which include Rotary, Snap, Push Button, Tap, Despard Style, Tumbler & Toggle. They come in single-pole, double-pole, 3-way, 4-way, High/Low/Medium & momentary switches. And some unusual switches as well. You can go to my store to see what I currently have listed. I also have a backlog of switches I haven't listed yet, so if you need a particular type of switch (brand name, size, etc.) or quantity, please contact me and maybe I have what you need.
Unique among vintage switch sellers, I thoroughly clean and test all my switches to ensure they are in proper working condition.
