One of the lighting voice-activated switch circuits using thyristors
Source: InternetPublisher:黄土马家 Keywords: Sound-activated switch switching circuit thyristor Updated: 2021/09/13
It uses relay control. The characteristics of this voice-activated switch are: when clapping for the first time,
the load is turned on (the light is on); when the hand is clapping for the second time, the load is cut off (the light is off). It can be used for corridor or residential lighting control.
The sensor (microphone B) can use a head-mounted microphone or a carbon microphone, or a CR22-9 condenser microphone used in recorders
.
It uses thyristor control. The characteristics of the voice control switch are the same as Figure 2-107.
