Switch that goes on/off about 100 times a minute

[ivanmax]

Hi everybody,

I would like to build a switch that goes on/off about 100 times a minute. Could I built the circuit in that squematic:

And take the lug where it says "salida" (output) and hook it into that other circuit:

Would in that way get what I am looking for?

Thanks a lot in advance for your help.
