Can 4 Pin Tactile-Micro be Used as On-Off Switch?

[Kussy]

Can we used the 4 pin Tactile-Micro as a on-off switch?

hi Kussy

would you like to clarify a bit ... a 4 pin Tactile-Micro what ?

I assume you mean switch ? like one of these ...

I'm not aware of any that stay on ... ie they are all push make - release break

Yes that one in the picture

Yes that one in the picture

It's just break the circuit and go off

 

[davenn]

OK there are ways to use this style of switch to be able to switch a circuit on and off

here's one example ...

this process is common in so much gear these days ... TV's VCR's DVD players etc etc

you will understand that that portion of the circuit will always have power on it


cheers

Thank you davenn that's very useful

no probs

if you do build this to experiment, you may find it suffers a little from switch bounce

that is a pulse produced when contacts make and another when they break. This will cause
double triggering in the flipflop IC

there is a small mod that can be done to stop that
