Abstract
A mechanically actuated power stealing solid state low energy switch providing a drop-in replacement for low energy mechanical switches. The present switch eliminates disadvantages of the mechanical switches. Power stealing is done on a constant basis to eliminate spikes, which might interfere with digital logic. Stealing logic with no diode drops allows low power operation on single CMOS substrate and omni-directional hook-up of a power supply with the most negative voltage being directed to the substrate. Hysteresis for the solid state switch is provided to mimic mechanical switch operation but without chatter of the latter.
