Hi,

I'm looking at making a sensor that will sound a buzzer and turn on an LED for a second or 2. I'm going to use a Reed switch but my question is, because the magnet will only get close to the reed switch for a split second, will the LED and Buzzer only sound for that split second or will the reed take a second to retract allowing for the buzzer and light to stay on for that second?

thanks
