Jon has been hard at work testing a button pusher and a light – both off the shelf – and developing a switch design. He’s confirmed that the button pusher is water resistant by keeping it submerged under 2m of water for a few days. The switch (shown below) is a simple springy piece of metal that will be attached to the surface of the PCB (printed circuit board).

Jon has been working on the dimensions of the switch, as well as its placement on the PCB relative to the edge. He set up a dummy board within a 100mm-long case with nine holes in it for the button pushers. Adjacent to the holes and along the dummy board, Jon played with various placements for the switch.
Mockup to test placement of the switches.
A few switches on the dummy board.
Jon was able also to test the combined action of the button pusher and the switch.
Through all the testing, Jon is confident about the dimensions and placement of the switch.
He also has been playing with a light from Lucky Light.
The light draws very little power and diffuses the LEDs evenly.
Jon is here holding the light behind the display.
