ReadySleep / light switch


People are faced with sudden darkness before sleeping because electric light is turned off without delay. It is one of inconvenient elements before going to sleep.
ReadySleep is the switch of a spring mode to solve the problem when you turn off the switch.

Once you turn the switch, it will be automatically switched off after 60 seconds.
During that time, you can prepare your sleep and you can go to bed more comfortably.
