I'm kinda doubting my self on weather this schematic needs a moment contact switch or not in order to work the way I want it to. I need a timed switch that will run a small fan for an X amount of minutes after pressing a button, kinda like with lights in blocks of flats. Press the button and the light goes on for say 5 minutes. Am I correct that I need to place the moment switch on either pin 2 or on pin 8 from the NE555P. Pin 2 = trigger Pin 8 is VCC Project is here [https://easyeda.com/GerritMax/delay-on-timer-230v](https://easyeda.com/GerritMax/delay-on-timer-230v) Dont really want to mess this up as it'll be switching 230 volt.
