Wire Gauge
Electrical Schematic Symbols And Definitions FUSE - A component in an electrical circuit that will open the circuit if too much current flows through it.
The circle indicates that the component has screw terminals and a wire can be disconnected from it.
REED SWITCH - A switch whose contacts are controlled by a magnet. A magnet closes the contacts of a normally open reed switch; it opens the contacts of a normally closed reed switch.
No circle indicates that the wire cannot be disconnected from the component. T
This indicates that the component does not have a wire connected to ground. It is grounded by being fastened to the machine.
200-BK-14
Circuit Number Identification
Normally closed switch that is open due to an applied condition, and will close again with a specific decrease in that condition.
This indicates that the component has a wire connected to it that is connected to ground.
9X-1123 325-PK-14
SENDER - A component that is used with a temperature or pressure gauge. The sender measures the temperature or pressure. Its resistance changes to give an indication to the gauge of the temperature or pressure. RELAY (Magnetic Switch) - A relay 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 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. 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. 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.
