Hi Nano,
Found it pretty quickly (2minutes); was amazed...
Okay, here goes in ASCII:
---------
-----| R2 |------ +9V
|K1 |-------|
|
----------------- -------------
| | | | |
| | | | ( )
--- - --- *---- ( ) Relay coil
--- | | --- ( )
|C1 | |R1 pushbutton |
| - switch GND
| |
GND GND
My first every try at an ASCII schematic...
Not bad eh?
My other notes:
C1=2200uF
R1=100 ohm
R2=150
K1= contact of the relay ('output' or switched contact)
With all the other contacts of the relay (K2,K3,etc) being used to switch useful things, i.e. the other contacts can be used for what you need to switch on/off.
With the pushbutton switch, you can energize AND de-energize the relay; has to do with the energy stored in the capacitor. They said it worked but you might need to tweak the various resistances and capacitor.
I have never used this schematic before, but it should work.
Hope this is of help,
