(...) I agree the simplest solution is to use a single switch with one linkage operated by the forklift to switch it on, and another linkage operated by the falling crate, that switches it back off, ready for the forklift. ROSCO (20 years ago, 22-Aug-05, to lugnet.robotics)

(...) Since turning the 9V wire connectors 90 degrees reverse the polarity, can't you play with how the wires are connected to the switches to re-reverse the polarity on one wire? (...) -Kyle (20 years ago, 22-Aug-05, to lugnet.robotics)

(...) Some parts are tracked in the Peeron database as to when they changed, like the "Plate 1 x 1 with Clip Vertical" (4085a, 4085b, 4085c), which had 3 versions (Type 1: 1979-1987, Type 2: 1987-1992, Type 3: 1993-present). Other types of changes, (...) (20 years ago, 22-Aug-05, to lugnet.parts)

(...) 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)

(...) Hi Brian, How will the package arriving at the other end "throw a switch?". Is there enough friction between the package and the belt? 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)
