This is a Touch Switch with Digital Output Circuit Diagram control key by touch simple, it uses a 4011 IC. The output logic HI has its pulse delay time controlled by C1. In the case is C1 4.7uF controls the pulse width for 1 second, then the touched the plate. Nothing prevents you from being done tests with other values ​​of C1.

TOUCH SWITCH 1 This circuit detects the skin resistance of a finger to deliver a awfully tiny current to the super-alpha try of transistors to show the circuit ON. The output of the "super transistor" activates the BC 557 transistor. The voltage on the highest of the world is passed to the front of the circuit via the 4M7 to require the place of your finger and also the circuit remains ON.  To turn the circuit OFF, a finger on the OFF pads can activate the primary transistor and this may rob the "super transistor" of voltage and also the circuit can close up. TOUCH SWITCH-2 This circuit detects the skin resistance of a finger to show the circuit ON for concerning one second. The output are often taken to a counting circuit. The circuit consumes no current when in quiescent mode: http://streampowers.blogspot.com/2012/07/touch-switchs.html 

The Gentle Touch Circuit Diagram . Consumer appliances these days hardly ever have a proper mains switch. Instead, appliances are turned on and off at the touch of a button on the remote control, just like any other function. This circuit shows how a device (as long as it does not draw too high a current) can be switched on and off using a push button. The approach requires that a micro controller is already available in the circuit, and a spare input port pin and a spare output port pin are required, along with a little software. When power is applied T1 initially remains turned off. When the button is pressed the gate of T1 is taken to ground and the p-channel power MOSFET conducts. The micro controller circuit is now supplied with power. Within a short period the micro controller must take output PB1 high. This turns on n-channel MOSFET T1 which in turn keeps T1 turned on after the push-button is released. Now the micro controller must poll the state of the push-button on its input ...

Apple has announced brand new versions of its iPod Touch, Nano and Shuffle music players The fifth-generation iPod Touch has arrived, alongside the iPhone 5, sporting a 4-inch multitouch screen and thinner, lighter body. Measuring 6.1mm thin and weighing 88 grams, expect up to 40 hours of music playback and 8 hours of video. Siri has also made the jump to the new iPod Touch. On the gaming front, the iPod Touch is 'the world's most popular music player... but a lot of people don't realize that it's also the world's most popular videogame player as well,' according to Greg Joswiak, Vice President for iPod, iPhone and iOS Product Marketing. 175,000 games are available on iOS to date and the new Touch will be taking full advantage of them with its new dual-core Apple A5 processor, offering graphics 7x faster than the previous Touch. The camera has also been upgraded to a 5-meg iSight rear-facing HD cam including backside illumination, an f/2.4 aperture and an identi...
