Logic Probe design help!

[mkv1091]

Im trying to draw the schematic of a logic probe. Every where i looked on the internet, did not help me much. Some of the connections are not shown in the following picture. Im lost on how to connect switch to it. D1, D2, D3, D4 are diodes. D5 and D6 are LEDs.

Here is the picture: http://imageshack.us/photo/my-images/21 ... probe.jpg/

Any help would be appreciated. Thanks.

What connections are not shown?
What do you want your switch to do?
