Simulation of Touch Sensor Switch Control Circuit

This paper is focus on simulation a kind of touch switch circuit which using a metal pieces as a switch. It is more convenient than the traditional mechanical switch and more durable. The simulation is based on PSPICE software and analog the action of a finger touch metal pieces. The simulation result shows that this circuit can be used as a switch and its power consumption is very low. This switch gets rid of the limitations of traditional switches, easy to use and can be applied to more cases, has a great prospect.
