Scaffolding: Unconventional Switch - Lock & Key

Our design for the Unconventional Switch assignment is based on a lock and key. The 5-volt PSU sends power through the resistors, then the LED which remains off until the switch is on which allows easy toggling of the LED. The switch is the lock and key. The key is grounded and when it comes into contact with the lock, the circuit is complete which allows the LED to turn on. The LED light turns on if the key comes into contact with the lock but might start flickering because the current isn't strong enough. If you insert the key fully into the lock, the LED will remain lit. The LED is a signifier to tell if the key is fit inside the lock.
