Ground (Case): This indicates that the component does not have a wire connected to ground. It is grounded by being fastened to the machine.

Ground (Wired): This indicates that the component is connected to a grounded wire. Thegrounded wire is 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.

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.

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.

Typical representation of a Sure-Seal connector. The plug and receptacle contain both pins and sockets.

Typical representation of a Deutsch connector. The plug contains all sockets and the receptacle contains all pins.

Symbols

Symbols And DefinitionsFuse - A component in an electrical circuit that will open the circuit if too much current flows through it.

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.
