3.7.7 SWITCHING DEVICES
Power switching devices are located as close as possible to the voltage source. Due to the distanc-
es between voltage source and cockpit, the most electrical loads are remotely controlled. With
the manually operated toggle and rotary switches on the instrument panel the pilot controls the
negative (ground) lines of control circuits of electro-mechanical or semiconductor relays, which
are located on the electric distribution board. The wiring of the load circuits is routed directly from
distribution board to load device the voltage drop between power supply and load to minimize.
