Harness And Wire Electrical Schematic Symbols
Fuse: A component in an electrical circuit that will open the circuit if too much current flows
through it.
Switch (Normally Open): A switch 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): A switch 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. The
grounded 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: 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.
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.
T
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.
Magnetic Latch Solenoid: A magnetic 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: 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.
