GRASSLIN 16 AMP 24-HOUR 7-DAY DIGITAL DIN-RAIL TIME SWITCH 03.90.0003.1

An Electrical Timer is an automatic switch designed to control the flow of power based on a specific duration or a pre-set schedule. It acts as the "brain" of a circuit, deciding exactly when equipment should be active. Whether it is a clock-based scheduler for a building’s heating or a high-speed relay managing a machines start-up sequence, the goal is the same: to turn a circuit ON or OFF automatically, ensuring efficiency and safety without a human needing to be there.
