Why Choose the Finder 20.22.8.230.4000 Modular Step Relay?
The Finder 20.22.8.230.4000 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 230 V AC coil and silver tin oxide contacts, the 20.22.8.230.4000 provides dependable switching of lighting and other compatible loads. Its 17.4 mm-wide DIN-rail enclosure and screw terminals simplify installation 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, silver tin oxide contacts, mechanical indication and manual test facility make the 20.22.8.230.4000 suitable for dependable lighting and building-control applications.
Typical Applications
- Lighting circuits controlled from multiple push-buttons.
- Residential and commercial building automation.
- Stairwell, corridor and communal-area lighting.
- Hotel, office and hospital lighting control.
- Electrical distribution boards.
- Industrial control panels.
