Normally open switch that will close with an increase of a specific condition (temp-press-etc.).

Normally open switch that is closed due to an applied condition, and will open again with a

specific decrease in that condition.

Normally closed switch that will open with an increase of a specific condition.

Normally closed switch that is open due to an applied condition, and will close again

with a specific decrease in that condition.

The circle indicates 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.

This indicates that the component has a wire connected to it that is connected to ground.

This indicates that the component does not have a wire connected to ground. It is grounded

by being fastened to the machine.

Symbol

FUSE - A component in an electrical circuit that will open the circuit if too much

current flows through it.

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.

CIRCUIT BREAKER (C/B) - A component in an electrical circuit that will open the

circuit if too much current flows through it. This does not destroy the circuit breaker

and it can be reset to become part of the circuit again.

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.
