Mechanical switches have a lot of disadvantages. Vibrations or gasoline destroy the active surface of these switches. You will often see a bad switch only when it is too late. Usually it works on the ground and fails in the air when the engine is running.
Old fashioned electronical switches use FET transistors but they also have a big problem: What happens, when the transistor dies ? Even electronic parts can fail.
The FET switch contains a rigid mechanical switch which is supervised with an electronic low voltage FET. Normally the current flows through the mechanical switch which is continously checked by the electonic circuit. A switch problem will be detected in almost zero-time and the FET will then handle any current up to 10 amperes. The output voltage will not have any visible drop and is well suited to power your receiver system.
For additional security two of these switches can be used with a double receiver power supply.
