Why Choose the Finder 27.28.8.230.4000 Electromechanical Step Relay?
The Finder 27.28.8.230.4000 is an electromechanical step relay (impulse relay) from the Finder Series 27, designed for reliable switching of lighting and compatible electrical loads using momentary control impulses. It provides a practical solution for residential, commercial and building services installations requiring lighting control from multiple locations.
As part of the Finder Series 27 electromechanical step relay range, this device uses a mechanically maintained switching mechanism to retain its selected contact position without continuous coil energisation. Its impulse-operated design enables convenient control through momentary push-buttons, reducing the need for complex conventional multi-way switching arrangements.
The Finder 27.28.8.230.4000 operates with a 230 V AC control coil and is designed for integration into suitable electrical installation and lighting control systems. Its electromechanical construction makes it suitable for applications requiring dependable impulse switching and multiple switching positions.

Reliable Impulse Switching for Electrical Installations
The Finder 27.28.8.230.4000 provides an efficient method of controlling electrical loads using short control impulses. When a suitable momentary push-button is operated, the relay's electromagnetic mechanism advances its switching position. The mechanical arrangement retains the selected state after the control impulse ends, allowing the connected circuit to remain in its required condition without continuous coil energisation.
This operating principle is particularly useful for lighting installations with several control points, including stairways, corridors, communal areas and commercial buildings. Multiple push-buttons can be arranged to control a common relay, simplifying lighting control wiring and providing convenient operation from different locations.
Typical Applications
- Residential lighting control systems.
- Stairway and corridor lighting circuits.
- Multi-point push-button lighting installations.
- Commercial building lighting control.
- Communal areas and shared building facilities.
- Electrical installation and refurbishment projects.
- Impulse-operated switching of compatible electrical loads.
- Building services and lighting automation systems.
