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.

MAGNETIC LATCH SOLENOID - A magnetic latch solenoid is an electrical component that is

activated by electricity and held latch 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.

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.
