Water Rocket Forum

This tutorial will show you have to construct a very reliable and lightweight acceleration switch which you can use to activate electronic systems on your rocket such as a ServoChron(tm) 2 Dual Servo Actuated Parachute Recovery System. The design of the U.S. Water Rockets Launch Detect Acceleration/G-Switch is the lightest and most reliable design that we are aware of, besting other designs by an order of magnitude. Our best scale can resolve 1/10th of a gram and this switch design does not register on the scale so it weighs less than 0.1g. Our design is also very easy to adjust for different sensitivity or different applications.
