T

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.

T

Switch (Normally Open): A switch that will close at a specified point (temp, press, etc.). Thecircle indicates that the component has screw terminals and a wire can be disconnected from it.

Receptacle

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.

Reed Switch: A switch whose contacts are controlled by a magnet. A magnet closes thecontacts 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 sendermeasures the temperature or pressure. Its resistance changes to give an indication tothe 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 acoil that makes an electromagnet when current flows through it. The electromagnetcan open or close a valve or move a piece of metal that can do work.

Symbols and Definitions

Fuse - A component in an electrical circuit that will open the circuit if too much current flowsthrough 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.
