Abstract:
1. A mechanism to disconnect an electronic device from a power source comprising: a user-actuable switch; an electronically controllable switch to couple the power source to the electronic device, and connected in parallel with the user-actuable switch between the power source and a power supply of the electronic device; and, a feedback mechanism to turn on and off the electronically controllable switch in response to actuation of the user-actuable switch, wherein the user-actuable switch is a momentarily on switch, such that the user-actuable switch upon actuation to turn on the electronic device momentarily couples the power source to the electronic device until the electronically controllable switch is turned on and couples the power source to the electronic device, and wherein where the user-actuable switch, after actuation, is released prior to the electronically controllable switch being turned on, the power source becomes decoupled from the electronic device and the electronically controllable switch does not turn on.
