    DC power supply on/off switch and indicator to left powers components to the right. Electromagnetic relay switch turns motor load on/off controlled by remote switch. Relay is used when the coil control switch itself is not designed to switch the required load type and a remote isolated control switch is needed. The central electrical interface bus connects and distributes power, control, sensor and load components.

    Example: Pilot turns ventilation fan motor on/off in tail of aircraft from cockpit switch. DC power supply was switched on and indicator "on" checked during pre-flight check out procedures.
