Two months ago I got a 4-digit dekatron counter there. /mike

No problem. Actually, you could use as a switch. Just make your circuit using pins 2 and 3. You would insert a plug into the jack which would open the circuit (turn off). Not a good way to do it and

Thanks nixiebunny and michailrw. I guess I was mistaken. I thought it would be an easy way out for an on/off switch. No wonder it made no sense. Thanks! -Mike

When comparing the truth tables between the 74141 and the DM8880N if 1111 or LLLL is implemented by Moses to blank the display for his 6-digit controller then the digit "F" would be displayed instead

It's not a switch. It's a power jack. Typically... Pin 1 (tip) = positive (from a power supply and to the device) Pin 2 and 3 would be closed (if nothing is plugged into the jack). - Like using

Although the design is simpler, and not really following a log curve, you'll find an application on my site: http://constructions.f6fkn.com/topic/index.html One of the schematics will probably help
