Hi, Billy Mays here, I'm sure most of you have lots of appliances to control, and many times you even forget to turn them off (black and white video of a lady running to turn the heater off when a huge red cross falls over her, crushing her body and soul, while Satan laughs in a corner...), well, with this revolutionary circuit you can forget about that. It includes cutting edge technology like resistors and switches. Just press the button, the capacitor will charge instantly, this charge is then used to feed the base of a 200hFE transistor, that feeds the base of another one for extra sensitivity. The last transistor switches enough current to power a relay, keeping a device activated. When the capacitor runs out of charge the relay will come back to it's normal state, switching off your device, preventing mishaps, house fires, opening portals to hell, and the world's apocalypse.

Additional notes:
The relay won't draw more current than the one determined by it's coil resistance, the relay in the simulation is ideal, the real ones don't draw so much current, no resistors are needed.
The time the device it's on is fully adjustable, just change the value of the capacitor or the resistor (as long as there's enough current flowing through the base).
