PressureSymbol T TemperatureSymbolLevelSymbolFlowSymbolCircuit Breaker Symbol Harness and Wire SymbolsSymbolsSymbols and Definitions Harness And Wire Electrical Schematic Symbols Fuse:  Acomponent in an electrical circuit that will open the circuit if too much current flows through it. Switch (Normally Open):  Aswitch that will close at a specified point (temp, press, etc.). The circle indicates that the component has screw terminals and a wire can be disconnected from it. Switch (Normally Closed):  Aswitch that will open at a specified point (temp, press, etc.).No circle indicates that the wire cannot be disconnected from the component. Ground (Wired):  This indicates that the component is connected to a grounded wire. Thegrounded wire is fastened to the machine. Ground (Case):  This indicates that the component does not have a wire connected to ground. It is grounded by being fastened to the machine. Reed Switch:  Aswitch whose contacts are controlled by a magnet. Amagnet closes the contacts of a normally open reed switch; it opens the contacts of a normally closed reed switch. Sender:  Acomponent 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. T Relay (Magnetic Switch):  Arelay 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. Magnetic Latch Solenoid:  Amagnetic latch solenoid is an electrical component that is activated by electricity and held latched 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. Solenoid:  Asolenoid 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. 12  AG-C4111-7898L-C123E-51799X-1123 Component Part Number  Pin or Socket Number Part Number:  for Connector Receptacle Part Number:  for Connector Plug Harness Identification Letter(s): (A, B, C, ..., AA, AB, AC, ...)
