Obi Wan Kenobi Lightsaber - clamp activation

After watching a few specific parts of the movie again, Obi Wan activates his Lightsaber by pushing down on the clamp top (bubble strip). I have found some small switches that will fit inside the clamp and have designed a switch holder that will fit inside the clamp. Because there are quite a few sabers with graflex clamps I should be able to reuse the same part on multiple builds (Luke v2, V3 and a Graflex saber).

There are similar switch housings available but I figured I would make my own because the switches I brought are slightly different and hey if you can make your own why not!
