Often you want to turn on and off power to a device with a single pushbutton switch. The circuit below performs this logic function with just a few tiny parts and can operate from DC supplies between +2v and 5v. It uses two inverters within a 6 pin SN74LVC2G14 device from Texas Instruments. Each press of the button toggles between the two on/off logic states. The logic output is connected to a PMV65XP p-channel FET from Philips. This component should be able to handle 2 amps of current Source: discovercircuits
