00:00:00but when you first turn a machine on there's no way of knowing what position the servo motor is in so in order to do that I thought I would introduce some limit switches but as it turns out this actually seems a little bit large for
00:00:14what I'm trying to do here but you can see how this works that something would run past here or bump into this and it would activate this switch these are marked in three different positions for uh n o n c n c this means that this is
00:00:34nor the normally open position the normally closed position and this is the common position so this would be shared between each of these two positions but you really only need two wires to connect to any limit switch depending on
00:00:39whether you want it to be normally open or normally closed
