Touch switch
Following circuit used for turn ON-OFF the electronic devices by touch IC 555 can give 200mA as maximum current in output so if you want to run loads with more current you have to using a power transistor or a relay as switch. By using relay you can switching 110-220v electric devices up to 10A. You can run this circuit by 3 to 18v according to load voltage. limitation of this circuit : it does not operate with mitten You can find other touch switch circuits in following link: https://engmousaalkaabi.blogspot.com/search/label/Touch%20switch Parts list: IC555 Resistor 1M Battery Note: IC555 will burnt if you connect the battery incorrect, so pay attention to battery polarity.
