BASIC ELECTRICAL COMPONENT 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

Switch (Normally Closed): A switch that will open at a specified point (temp, press, etc.).

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.

Relay (Magnetic Switch): A relay is an electrical component that is activated by electricity.

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: An electrical component that is activated by electricity and held latched by a

that the component has screw terminals and a wire can be disconnected from it.

No circle indicates that the wire cannot be disconnected from the component.

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.

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.
