Latching transistors

Starting basic. Trying to build a low power latching circuit to light a reading light that can eventually be turned off by a timer pulse. 

So, staring with a two transistor latching circuit with a transistor that can be pulled to turn it off. Connected via a switch for now.

Remove the 1uF capacitor and the circuit will function correctly...👍

There is no need to remove the 1uF cap. It does work fine as is. @mpvinci, don't let you irritate by Trolls which have no knowledge about electronics and just mess with your circuit. @lenzrulz is one of the biggest frauds we have here on everycircuit.

Set simulation speed faster

@hurz, thanks for the heads up. @lenzrulz, the capacitor is there to prevent false starts on the npn transistor. Thanks for the tip though. I will update the sim speed. I appreciate the tips all.
