The Switch Jack is reliable and convenient way of of controlling your planes electrical system, as well as charging your flight batteries without removing the canopy! I will explain for those of you who are unfamiliar with this method. The switch jack method uses an electrical connector comprised of two components, the male plug and the female receptacle. The receptacle is threaded through a hole in the fuselage and is held in place with a nut. If you are installing it into a foam plane the jack can be simply glued into the fuse. The receptacle contains a switch that is triggered when you insert the plug. The planes electrical system is "on" when the plug is removed from the jack. When you insert the plug into the jack, the planes electrical system turns "off" and a connection to the flight battery is established through the plug. The plug is provided with a 2 inch power cable terminated with a JR style servo connection that plugs into your battery charger.
After designing the prototypes we worked with our manufacturer to find a power jack we would feel confident flying in our planes. This meant a robust switch contact. The jack we decided to use is strong, light weight and low profile. The jack protrudes into the fuselage less than one half inch, as the leads are soldered to the sides of the jack instead of the bottom.
What you get:
FYI: At the rear of the switch jack is an exposed conductor carrying positive power from the battery (See pic below). Under normal circumstances this is a non issue, but we feel it is important for you to be aware of. If it is a concern, the conductor can be easily insulated in a number of different ways. Hot glue, a dab of Plasti Dip, even a few coats of enamel model paint will provide reasonable insulation.
I used to have a choice.. Pay a bunch of money for a pre-built charge jack, or build my own. A friend showed me some he bought from Aloft and I was impressed. They are actually nicer than what I was making for myself and cost less than the parts I was buying! I really like the 90 degree plugs they include. I have not seen this option anywhere else. The plugs are molded to the wires, so they should be very trouble free. I am really impressed with how well thought out and how well built these are. Keep up the good work!
