Brainstorming in the shed tonight but my brain wasn't cooperating much. Still, after a sit down and a few uppercuts, I managed to get the grey matter to work for a living.
1. Experimenting and making a DIY linear actuator for the helmet face plate.

2. Building tiny mounting plates for micro switches.

3. Micro switch mounted on the upstroke hinge. I've made them adjustable so I can tune their height once the actuator is connected.

4. Micro switch mounted under the downward faceplate hinge. This bracket will be re-made as one piece. I had to make it in two for prototyping to get the angles right.

5. The plotting continues. Linear actuation concept drawing. How to attach the actuator to the hinge.
