Why Choose the Finder 26.02.8.048.4000 Impulse Relay?
The Finder 26.02.8.048.4000 is a compact and reliable 10 A electromechanical impulse relay designed for controlling lighting circuits from multiple push-button switches. As part of the Finder Series 26 impulse relay range, it provides an efficient switching solution for residential, commercial and building automation installations requiring dependable multi-point lighting control.
This relay features a 48 V AC operating coil and two normally open (2 NO) contacts, enabling two electrical circuits to be switched simultaneously through a momentary control pulse. Its mechanically maintained switching mechanism retains the selected contact position after the pulse ends, eliminating the need for continuous coil energisation and helping reduce energy consumption.
With a 10 A rated switching current, a maximum contact switching voltage of 400 V AC and silver tin oxide (AgSnO2) contacts, the Finder 26.02.8.048.4000 is suitable for compatible lighting and electrical load control applications. Its compact design and screw terminal connections allow straightforward installation in suitable electrical mounting boxes and fixed wiring systems.

Reliable Impulse Switching for Multi-Point Lighting Control
Impulse relays such as the Finder 26.02.8.048.4000 provide a convenient alternative to conventional two-way and intermediate lighting switch arrangements. Multiple momentary push-button switches can be connected to the relay control circuit, allowing the same lighting installation to be operated from several different locations.
When a suitable 48 V AC control pulse is applied, the relay's electromagnetic mechanism changes the state of its two normally open contacts. The mechanically maintained switching system holds the selected position after the control pulse ends, so the operating coil does not require continuous power to keep the connected lighting circuits switched on.
The Finder Series 26 is designed for compact electrical installations where reliable lighting control, straightforward wiring and efficient switching are essential. Its 10 A contacts, silver tin oxide contact material and compact mounting-box format make it a practical choice for electricians, building automation engineers and lighting control installers.
