Abstract

A touch operated switch for control of electrical lighting, appliances, machinery and equipment which requires non sparking fail-safe operation. The switch utilizes digital complementary metal oxide semi-conductor technology which requires nearly insignificant standby power and incorporates a unique count down reset circuit which prevents extraneous operation from static discharge, radio frequency (RF) signals or power line transients. The switch will only respond to the electromagnetic flux generated by the power source that the controlled load is connected to. All other signals or pulses of differing frequencies are ignored by the switch thereby preventing inadvertent operation. Due to the limited number of discreet components utilized the total cost of manufacture will be extremely low and is expected to be less than the present manufacturing cost of the standard wall-type light switches that this invention will replace. The switch also simplifies inventory control due to the fact that a single switch type replaces all of the multi-pole mechanical switches currently utilized to provide switching capability from various locations.
