Well, i built this circuit(see attachment) to be used in a switching application. I used the same values of components as given in the schematic except the Electrolytic cap--i used 1uF instead of 0.1uF coz i had that by me then. Vcc in my case is about 8.4V. The problem is that the output pin is always at a Pd of 0V across Ground 8.5V across Vcc--even after pressing the switch. Please help
