SWITCH Knob / door knob


Convenient and direct, that's the SWITCH Knob. When people go out, they often forget to

switch off the electric equipments in the house. Not only does it make a huge waste of

electricity, but also creates a safety hazard. Designed with power switch inside, SWITCH

Knob solves this problem. You can switch off all the electric equipments as you lock the

door before you go out. Therefore the behavior of switching off needs no reminder, and

needs no redundant operation.
