Hello all,
I would like to make a very simple circuit w/an SCR. It is my understanding that once the switch is activated the SCR gate will stay open. I have attempted to do this, but the "gate" will not stay open. I would like to use a NO microswitch and a buzzer with a 9V battery. I can get the microswitch to work, but once activated it will turn off (buzzer stop sounding) when the lever is released. I have looked online and I do not understand how come I cannot get it to work. Thanks for your help.
