Coin the light / lamp

Coin the light
Coin the light

It is a lamp with a different switch!
When a user uses this lamp , he/she has to throw a coin instead of pressing the switch.
I use the electricity conductivity of coins to design coin as a switch.
When a user throws the coin , it sticks in the slot , close the circuit and lights up the lamp.
With this concept , The coin is not just only a "switch" to the light, but also remind you of the value of energy sources.
