The special Relay that used replace normally relay, very fast contact load, low voltage input 3V to 24V only
This is overload protection for transformers and load, is simple circuit cut off-on by relay. And so fast switch witch SCR driver. can set sensitive by VR1
This is speed motor controller circuit of 12V DC motor. as SCR DC motor speed control circuit using IC-4081 CMOS. You can adjust the speed of rotation [...]
This is Sound switch circuit,using IC-1458 and SCR-C106D It will work only if the loud is overdue,for player cameras, can apply to a Burglar alarm circuit
Power failure, voltage drop, power surge, but do not worry when has this circuit.
This is Electronic Rotary Switch circuit using Digital IC,use a single switch choose a function of external control circuit has 9 positions,Begin with S1
