| Aug 16 at 14:30 | comment | added | Michal Podmanický | Sure. The series capacitor passes the voltage to pins 1&3 just temporary (like 100ms), then goes off. But as I sad if you use just two of this circuits the pins 1&3 are feed simultaneously (without pin3 delayed). To get a pin3 delayed use circuit I added to Edits. | |
| Aug 16 at 14:09 | comment | added | elektroplax | Like I said: Pin 1 + 2, then 2 + 3 and then there shouldn't be any voltage on 1 and 3. But with a single SPST switch this wouldn't work? | |
| Aug 16 at 14:03 | comment | added | Michal Podmanický | Yes. Both circuits connect to right side of Spst. | |
| Aug 16 at 14:00 | comment | added | elektroplax | Two of this circuit with one SPST? | |
| Aug 16 at 13:51 | comment | added | Michal Podmanický | The bottom line is Gnd. For pin3 it depends if it needs to be delayed after pin1. If not just use two of this circuits. If yes you need to make a delay with transistors. | |
| Aug 16 at 13:44 | comment | added | elektroplax | Thanks, but what's with pin 3? Is it the bottom right line? | |
