Definitions:

Terminals

The end points of an electrical device or a cable where connections are made to enable the flow of electrical current.

Diode

A semiconductor device that allows current to flow in one direction only, used in electronics for rectification and signaling.

Relay

Any of a number of devices that receives a signal and then effects an action. In vehicle electrical circuits, relays are used to allow a small current circuit to control a large current circuit such as in a starter relay. Also known as a pilot.

Transistor

A semiconductor device used to amplify or switch electronic signals and electrical power, fundamental in modern electronic circuits.
