I added a hardware switch to my x230 camera (I had it opened up anyway to do the FHD mod so I figured why not). It switches the power line of the internal USB port that the camera connects to. I placed a subminiature slide switch next to the camera, cut a notch in the casing, cut the supply trace between the camera's connector and filter capacitor, and soldered wires to the switch to either side of the cut trace. Then I drilled two 0.5mm deep holes with a drill bit held by hand for the bumps of the switch to sit in, and glued it in place. Works fine. I added a touch of glitter paint to one side of the switch slider so it's glittery when the camera has power. I haven't got around to doing the same for the mic. (yes, I do electronics for a living)
