Hilltree- Diy normal relay to pulse relay

This is a handy schematics/electronic, how to make with some standard electronics ,from a normal electrical relay to a pulse relay [bistable relay] . This is nice for the electronic mucisian [ footswitch on hold/ sequencer /modular e.d] .No i.c's or transistors are used. Resistor R3 is somwhat critical to the power input . Whith a 12 volt relay the power /resistor , 9V = 47 Ohm / 12V= 220 Ohm / 15V = 470 Ohm resistor. You can also use a small potentiometer for R3. Now works the momentary switch as a normal on-off switch. In the video i use a Korg S1 footswitch to demonstrate , but you can use any momentary switch for that.More at http://www.groenewoudnet.nl

you're welcome

I need a relay with 2 N.O contacts for this?
