Tim, I'm glad there's at least one other person here that can comprehend what I'm saying. Thank you very much. I believe I've now ruled that out as a possibility :P But we've still got our external circuit (with rotary switch, of course). To make the rotary switch work, just connect it to ground like the rules state... I see no conflict or need for breakers, etc, as FotoPlasma suggested.

Greg,

Not the E-Stop but the Robot Reset button on the Operator Interface.

Ryan,

You are 100% correct, Rotary switch, Toggle switch or Limit switch they are all 1's and 0's to PBasic.

Sorry. I didn't read carefully, and I got confused by Ryan's earlier reference to another thread concerning the e-stop button.

the rules say that you must have "All additional electronics must draw power from a 20A circuit breaker," but if you look above, the limit switch is essentially the same as a rotary switch except the rotary switch has more possibilities for outputs. i see this as many limit switches in one module. therefore, there would be no need to hook it up to a fuse.
