Why Choose the Finder 20.22.8.110.4000 Modular Step Relay?
The Finder 20.22.8.110.4000 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 bistable electromechanical 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 and a 110 V AC coil, the 20.22.8.110.4000 provides practical control of lighting and other compatible loads. Its compact 17.4 mm-wide DIN-rail enclosure, IP20 protection 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 bistable mechanism, contact-status indication and manual test facility make the 20.22.8.110.4000 particularly useful in building-control systems where reliable, easily maintained switching is required.
Typical Applications
- Lighting circuits controlled from multiple push-buttons.
- Residential and commercial building automation.
- Stairwell and corridor lighting control.
- Electrical distribution boards.
- Industrial control panels.
- Remote switching of compatible electrical loads.
