Touch Switch Circuit Using Transistor, TOUCH definition: 1. To be or come into contact: Don't let the live wires touch. The first transistor is amplifying the gain first and then it is further amplified and multiplied by the second transistor so as a result, we get a very high gain. Learn more. A circuit diagram of resistive touch sensor using BJT is shown in Fig. It is also a very poor design as the biasing (turn-on) for the output transistor is via a resistor and the output transistor is turned off by taking the biasing current to the 0v rail.
