Step Relays – FINDER: Technical Overview and Commercial Solutions
Step relays, also known as impulse relays or latching relays, are electromechanical switching devices designed to alternate between two stable states (ON/OFF) with each successive pulse of the control signal. The FINDER range of step relays typically features coil voltages from 12 V AC/DC to 230 V AC, rated currents up to 16 A, and contact configurations such as 1P, 2P, or 3P. These relays are built for DIN rail mounting (EN 60715) and often include mechanical indicators and manual test buttons. They are characterized by low power consumption in standby (typically <0.5 W) and high switching endurance, making them ideal for sequential control applications.
These relays are predominantly used in building automation, lighting control systems, staircase lighting timers, and HVAC control panels. They are installed in electrical distribution boards, home automation cabinets, and industrial control panels where sequential switching of loads (e.g., lighting circuits, motor starters) is required. Their latching mechanism ensures the relay maintains its state even after a power failure, providing safety and energy efficiency in critical installations.
Key subcategories within the FINDER step relay portfolio include the 20.21 series (1P, 16 A, 230 V AC coil), the 20.22 series (2P, 16 A), and the 20.31 series (3P, 16 A). The article code structure typically follows the pattern: 20.21.0.024.0000, where the first two digits indicate the series, the next two the number of poles, and the following digits specify coil voltage and packaging variant. These relays are available with optional accessories like push-in terminals or plug-in sockets for quick wiring.
