Touch Motor Control by SCR and Schmitt Trigger

This circuit designs for control DC Motor 12 volts. By use the touch on the plate, the Motor as a result turn go to once.
When use a finger touches the metal plate makes Schmitt Trigger Circuit (by IC-4011 nand gate CMOS) take a signal from Oscillator Circuit and make a signal goes out to bias current a base of Q1-2N5088 works and then it will be trigger a SCR1 to drive the DC Motor 12V then turn follow want.

- For power supply type of DC Motor this must be AC current 12 Volts Only. Because of make SCR not bias during negative current there.
- And this circuit works not heavy DC motor power, turn ? do not turn ? Then don’t have to stick heat sink give SCR1-2N4441 for DC motor you will may use motor at use in an automobile all right. Request enjoy.
