Why Choose the Finder 20.22.9.012.0000 Modular Step Relay?
The Finder 20.22.9.012.0000 is a compact and dependable modular step relay designed for impulse-controlled switching in lighting, building automation and electrical distribution applications. As part of the Finder Series 20, it changes contact state whenever its coil receives a momentary control pulse.
Its electromechanical latching operation enables electrical loads to be controlled from multiple momentary push-buttons without requiring the coil to remain continuously energised. A mechanical position indicator and test button support convenient inspection and manual operation during installation, commissioning and maintenance.
With two normally open contacts rated at 16 A, a 12 V DC coil and silver nickel contacts, the 20.22.9.012.0000 provides dependable control of compatible lighting and electrical loads. Its 17.4 mm-wide enclosure mounts directly onto a 35 mm DIN rail inside distribution boards and control panels.

Efficient Impulse Control for Lighting and Electrical Loads
A modular step relay changes its output state each time a momentary voltage pulse is applied to the coil. This allows one electrical load to be switched from several push-button locations while avoiding complex conventional multi-way switching arrangements.
The Finder Series 20 is designed for installation in modular distribution equipment. Its latching mechanism, mechanical indication and manual test facility make the 20.22.9.012.0000 suitable for building-control systems requiring reliable 12 V DC impulse operation.
Typical Applications
- Lighting circuits controlled from multiple push-buttons.
- Residential and commercial building automation.
- Stairwell, corridor and communal-area lighting.
- Low-voltage control and signalling circuits.
- Electrical distribution boards.
- Industrial control panels.
