ABSTRACT:
A motor-driven alternator including an improved remote on/off switch closure detection system capable of detecting closure of solid-state switches. Such switches are typical of appliances, tools, or other electrical load devices. A sensing signal is provided by a higher voltage ac or pulsating dc signal for overcoming the forward breakdown voltage of semi-conductors typical of such switches. A detection circuit is included which comprises an opto-isolator circuit for isolation of the power and sensing circuits.
