2. Internal Micro-Switch Failure
Beneath the outside button is a tiny electronic component called a micro-switch. These switches are soldered onto the circuit board. Heavy-handed usage or drops can trigger these switches to break off their solder pads or just break internally.
3. Dirt and Carbon Build-up
