ACOUSTIC SWITCH

摘要

11 ACOUSTIC SWITCH The present invention is a light indicator for an acoustic switch which is connected so that this single indicator will produce a light only when both A/C power is supplied to the switch and an appliance is plugged into the switch and turned on ready to receive power. The switch has a microphone which produces an electrical signal when sound is detected. This electrical signal is supplied to an activating circuit which will activate a trigger device to couple the A/C line power to the connected appliance.
