Why Choose the Finder 26.04.8.024.4000 Step Relay?
The Finder 26.04.8.024.4000 is a compact and reliable 10 A electromechanical impulse step relay designed for lighting control, building automation and electrical installation applications. As part of the established Finder Series 26 step relay range, it provides convenient control of lighting and other electrical loads using momentary push-button signals.
Featuring a 24 V AC operating coil and two normally open (2 NO) contacts, this relay uses a mechanically maintained switching mechanism that changes contact state in response to successive electrical impulses. Unlike conventional monostable relays, the step relay retains its selected switching position after the control impulse ends, reducing the need for continuous coil energisation.
With a 10 A rated contact current, 250 V AC rated contact voltage and compact installation format, the Finder 26.04.8.024.4000 is suitable for residential, commercial and industrial lighting installations. Its box-clamp screw terminals and compact housing allow convenient installation behind suitable blanking plates or within electrical mounting enclosures.

Reliable Impulse Switching for Lighting and Building Automation
The Finder 26.04.8.024.4000 operates through an electromechanical step-switching mechanism activated by momentary electrical impulses applied to its 24 V AC coil. Each control impulse advances the relay through its defined switching sequence, changing the state of the connected contacts. The mechanical mechanism maintains the selected position after the impulse ends, allowing electrical loads to remain switched without continuously energising the coil.
This operating principle is particularly useful for lighting installations controlled from several locations. Multiple momentary push-buttons can be connected to the control circuit, enabling convenient switching without conventional multi-way switch wiring. The Finder Series 26 range combines compact installation, dependable contact performance and mechanically maintained switching for residential, commercial and industrial electrical systems.
Typical Applications
- Residential lighting control systems.
- Commercial building lighting installations.
- Staircase and corridor lighting control.
- Multi-location lighting control using momentary push-buttons.
- Building automation and electrical management systems.
- Office, retail and hospitality lighting installations.
- Electrical switching in suitable mounting boxes and enclosures.
- Impulse-controlled switching of appropriately rated electrical loads.
