I want to build a latching push button ON/OFF power switch which turns on by holding the switch for 3 seconds and turns off by holding the switch for 3-5 seconds. The following circuit is closest to what I need. How can I modify it to delay the turn on time? What is the function of the 10k resistor next to the switch? It looks like the circuit will also work without it. when the switch is not pressed, the 1uF capacitor is not charged, right?
