Title: using tactile switch to turn ON and turn OFF a circuit
Post by: tapasxplore on November 15, 2017, 07:29:37 pm

Hi,

I am planning to use tactile switch to turn ON and turn OFF a circuit (see attachment for schematic), I don't want to use slide switch for turning ON-OFF the circuit. I have narrowed down to SRC0  (Smart push-button on/off controller) from STmicroelectronics, is this right choice, or there are other more feasible alternatives available.

Regards,
Tapas

If I understand your requirements correctly...

Have a watch of Daves video:
