Methods, systems, and computer readable media described herein can be operable to facilitate transitioning a device from a first state to a second state. A switch described herein allows for the use of an electronic circuit to perform the toggle and persistence functions while simultaneously giving more flexibility to the industrial design and physical switch implementation. The switch allows this preserving of the state using only a toggle on a voltage and thus allowing for a hardware only solution. The switch described herein allows for the use of smaller and less complicated mechanical switches allowing for more compact industrial designs. The switch uses a programmable voltage reference as a 1 bit non-volatile memory cell that is programmed by means of a logic pulse to the device. This allows a software independent setting of the state of the privacy switch. This state will remain through power cycles.
