1. Suite Name: Clap switch kit.
2. Kit Model: PSK-1.
3. Operating Voltage: 5V.

Q1 and Q2 composed of two audio amplifier circuit, the audio signal is accepted by the MK1 C1 is coupled to the base of Q1 pole, amplified and fed
directly from the collector to the base of Q2 to a negative square wave at the collector of Q2, with to trigger the bistable circuit. R1, C1 circuit frequency
response is limited to about 3kHz to high sensitivity range. The power is turned on, the state of the bistable circuit Q4 off, Q3 saturated, D3 does
not
shine. When MK1 received control signal, and a negative square wave output after two enlarged, negative spikes through D1 add to the base of Q3,
the
circuit rapidly flip, D3 is lit after differential processing. When MK1 again connected to the control signal, the circuit and flipped, D3 is off. Circuit
board reserved for the terminal J1 access outside the control equipment and other devices through the J1 connector relay voice. (Then relays required
at both ends of the relay coil anti and a diode)
