Master switch

The Master Switch is a single switch that controls the electrical power to all circuits in an aircraft electrical system. It is considered the primary switch as it is responsible for controlling the power to all other electrical components in the aircraft. Essentially, it is the main power switch for the entire aircraft and is usually located on the aircraft dashboard within reach of the pilot. The Master Switch is an essential safety feature as it allows the pilot to quickly disconnect the entire electrical system in case of an emergency. This switch is also used during pre-flight checks to ensure that all electrical systems are functioning correctly before takeoff. The Master Switch differs from other switches in the aircraft as it controls power to all circuits, whereas other switches control power to specific electrical systems. An example of this is the landing gear switch, which controls the power to the landing gear system only. The Master Switch is an integral part of ensuring the safety and proper function of an aircraft’s electrical system.
