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. Theelectromagnet 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 DefinitionsFuse - 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 isactivated 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 placesthe latch coil circuit open at the time the coil latches.
