Slide switch
This is a slide phone that wakes up when it slides open. It is implemented with two hall sensors mounted
on the main PWB and a magnet fitted to the sliding mechanism. The hall detector output is active low (0V)
and 1.8V when not active. This arrangement makes the phone able to detect - closed and open position. The
two hall sensors are overlapping each other to cover the entire sliding range.
