How and what do I use to activate the circuits of an Alisha board to open my MK85 mask?

I've just finished printing my helmet and gotten my hand on an ALISHA board, and I've connected all the wires into where they need to go (using the help of Frank's "How to Motorize an Iron Man Helmet Part 3" video) and I need to know how I can activate the circuit to open my mask. In the video, Frank shows that the blue trigger wires are used to activate the circuit and open the mask, however I do not know what to use to connect to the trigger wires or even where to place it. I remembered Frank saying how he put a switch/button on the chin of the mask that he hits with his chin (lol) to open the mask, but I don't think it'll work with me because the wires won't be able to reach the chin from the board to the servos because the chin piece can detach from the helmet. (the helmet is also slightly a bit big but I've figured out how to fix this). What should I do?

You can use any sort of "momentary" switch. The most common thing people use is a "NO" (Normally Open) limit switch installed in the chin.

What would I use to get it to reach the chin?
