Our team uses the NXT running code so we are not using switches. However, I was just curious about how it could be done with switches. Here is what I came up with and it doesn't look like it needs any DPDT or even locking limit switches. It just needs one NO limit switch and one SPDT household switch. When the minibot deploys, it closes the NO limit switch and starts the motor climbing. After it hits the top, the SPDT switch flips and shorts the motors to ground causing it to brake. Depending on the weight of the minibot, it will either stay up there or slowly coasting down. I also came up with an alternate design where it will reverse the motor so it will climb down but with gravity helping, the minibot will practically crashing down very fast.
