|FET Security Switch||Features:
electronic and mechanic double check circuit
|Security switch improves reliability for your receiver power switching|
Already widely used in Germany, now availabe for worldwide shipping !
electronic FET security switch uses a totally new concept to make receiver
power switching more reliable.
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.
|This new FET security switch combines the
advantages of mechanical and electronical switches with a new circuit
design. Both types work in parallel which give high reliability and long
duration. This makes the operation of receiver systems much more secure.
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.
|This switch is ideal for models where high
reliability is an issue, like model helicopters, all models using gas
engines ... (All my R/C helicopters use this switch).
For additional security two of these switches can be used with a double receiver power supply.
