Normally closed limit switch diagram

WebThe “normal” status for a switch is the status its electrical contacts are in during a condition of no physical stimulation. Another way to think of the “normal” status is to think in terms of the switch being at rest. For a momentary-contact pushbutton switch, this would be the status of the switch contact when it is not being pressed. WebI believe high limit switches are normally closed, and they should always fail open. Which means when they go bad, or the temperature gets too high they open the circuit.
