The Mindstorms touch sensor isn't a switch, but a sensor. You need an RCX or MicroScout to read it's status. It is not suited for directly switching a load like a motor. It can only carry a very small current, and still has a lot of resistance when (...) (24 years ago, 12-Feb-01, to lugnet.robotics)
