Reliable Low-Voltage Control for Electrical Switching Systems

Modular installation relays such as the Finder 22.23.9.012.4000 allow electrical loads to be controlled through a separate low-voltage operating circuit. When the 12 V DC coil is energised, the relay's internal electromechanical mechanism closes the normally open contact and opens the normally closed contact. When the coil supply is removed, both contacts automatically return to their original positions. This arrangement enables complementary switching functions using a single control signal.

The Finder Series 22 is designed for electrical installers, panel builders and automation engineers requiring dependable switching within compact electrical enclosures. Its 20 A contact rating, durable silver tin oxide contacts and 1 NO + 1 NC configuration make it suitable for building automation, lighting control and electrical distribution applications. The integrated test button and status indicators simplify commissioning and troubleshooting, while the DIN rail mounting system allows convenient integration alongside other modular electrical components.

Typical Applications

• Residential and commercial electrical distribution boards.
• Remote switching of lighting circuits and electrical loads.
• Building automation and facility management systems.
• Low-voltage control circuits using 12 V DC supplies.
• Complementary switching using normally open and normally closed contacts.
• Electrical heating control within specified load ratings.
• Ventilation and building services equipment.
• Industrial electrical control panels and automation systems.
• Control circuits requiring two simultaneous contact-state changes.
• General-purpose electrical load switching and panel-building applications.
