DHC8A Time Control Switch

Product Overview

Based on ATST Electric’s core concept of “Precise Control, Safe and Reliable”, DHC8A Time Control Switch is designed for basic time-based automation in electrical systems. It enables automatic switching of electrical loads according to preset daily schedules, helping reduce manual operation and improve energy efficiency.

DHC8A focuses on simplicity, stability and cost-effectiveness. It is suitable for applications where complex programming is not required but reliable timing control is essential. The product adopts a mechanical or simplified electronic timing structure (depending on configuration), ensuring stable operation in long-term use.

With DIN rail installation design and compact housing, DHC8A can be easily integrated into distribution boards and control cabinets. It is widely used in lighting control, pump control and ventilation systems in residential, commercial and industrial environments.
