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.

966G and 972G Wheel Loader Electrical System

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.

T

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.
