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.
