reverse switches

Projects General Guidance

hi,

i was wondering if there are any reverse switches around? I would like to trigger a track on the MP3Trigger when the lid of the box is open. Everything is receding in the box and when the box is open it should playback. I will fix the switch (small ones with a metal handle sticking up) to the lid of the box. any suggestions?

Microswitches normally have both NO and NC contacts.
