Normally open switch that will close with an increase of a specific condition (temp-press-etc.). The circle indicates that the component has screw terminals and a wire can be disconnected from it. This indicates that the component does not have a wire connected to ground. It is grounded by being fastened to the machine. MAGNETIC LATCH SOLENOID - A magnetic latch solenoid is an electrical component that is activated by electricity and held latch by a permanent magnet. It has two coils (latch and unlatch) that make electromagnet when current flows through them.

It also has an internal switch that places the latch coil circuit open at the time the coil latches. Normally open switch that is closed due to an applied condition, and will open again with a specific decrease in that condition. This indicates that the component has a wire connected to it that is connected to ground. It has a coil that makes an electromagnet when current flows through it. The electromagnet can open or close the switch part of the relay. CIRCUIT BREAKER (C/B) - A component in an electrical circuit that will open the circuit if too much current flows through it. This does not destroy the circuit breaker and it can be reset to become part of the circuit again.

Normally closed switch that is open due to an applied condition, and will close again with a specific decrease in that condition. SOLENOID - A solenoid is an electrical component that is activated by electricity. It has a coil that makes an electromagnet when current flows through it. The electromagnet can open or close a valve or move a piece of metal that can do work. No circle indicates that the wire cannot be disconnected from the component. Normally closed switch that will open with an increase of a specific condition.
