Good quality and so simple to use Grasslin is the industry standard in plug in and integrated timers.
This standard segmental timer couldn’t be easier to use – each pin around its dial represents 15 minutes of a 24 hour day. Simply push the pins in or pull them out according to whether you want power ‘on’ or ‘off’. Make sure that you use in conjunction with a power controller if using to control your lighting. Power controllers, or contactors, buffer the large inductive current generated when lights are initially switched on, preventing timers such as these from being overloaded.
