(...) No, I think you should use one polarity switch, without handle to greatly reduce the friction needed to throw it. Putting the crate on the conveyor throws the switch, and when the crate gets to the other end it could push a lever, or better (...) (20 years ago, 22-Aug-05, to lugnet.robotics)

Will there be a mechanism in the belt itself to "go halfway and stop"? If you only used one polarity switch, (...) (20 years ago, 22-Aug-05, to lugnet.robotics)

(...) hmm. At first, I would say "No". When you flip your switches at home, the switches could be in either of two states when the lights are "on".
