I am trying to repurpose a scavenged motor, however the wiring diagram that's on it has a schematic symbol I have never seen and could not find on the Internet.
Anyone know what this is and what it means?
For more context, here's a reproduction of the entire schematic:
Update:
The symbol is for a thermal switch/contact. This particular kind is normally closed and opens on temperature rise (http://www.industrial-electronics.com/Electricity-Refrigeration-Heating-Air-Conditioning_5b.html)
Best Answer
It's a thermal contact (Normally closed - thermal trip).
If OP Googles "contact switch symbols" and jumps to the Images, he/she can find a lot of symbol tables. Here's one OP could see: ibiblio.org/kuphaldt/electricCircuits/Ref/01053.png
