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.
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.
