Finder 26.01.8.230.4000 Impulse Relay, 1 CO, 16 A, 230 V AC Coil, DIN Rail

In electrical installations, lighting circuits often need to be controlled from multiple points without complex wiring or continuous power consumption. The Finder 26.01.8.230.4000 impulse relay solves this by latching its contacts with each pulse, so the coil is energized only momentarily. This reduces energy use and heat, making it ideal for staircases, corridors, and large rooms with several pushbuttons.

Who is it for

Electricians and panel builders who install lighting control in residential, commercial, or industrial buildings. It suits anyone needing a reliable, compact DIN rail device that handles frequent switching and integrates easily into distribution boards.

Tips

For multi-location control, connect several momentary pushbuttons in parallel to the coil terminals. The relay toggles its state with each pulse, so no auxiliary power is needed to hold the contacts. Ensure the total load does not exceed the rated current and voltage, and consider contact protection for inductive loads.
