Need help selecting the right sensor

[thmeans06]

I am a mentor from Team 66 and we are looking in to adding a sensor on our robot that could detect when our robot is under the bar of the pyramid. Anyone have any ideas that are reliable and easy to fabricate?

We were thinking of a contact switch type sensor. If anyone has any photos or ideas of how we can do this I would greatly appreciate it! Thanks!

A limit switch sticking up out of the robot so it hits the bar and is pressed as the robot passes under would be a simple and effective solution.
