Finder 20.23.9.024.4000 Impulse Relay, 2 NO, 16 A, 24 V AC Coil, DIN Rail

The Finder 20.23.9.024.4000 is an impulse relay from the Series 20, designed for latching switching of lighting and other loads. It provides two normally open contacts and a 24 V AC coil, making it a reliable choice for push-button control circuits in residential and commercial installations.

Highlights

• Latching operation: the relay changes state with each coil pulse and holds position without continuous power.
• Two independent 16 A NO contacts for switching two separate circuits.
• Compact 2-module DIN rail housing, 35 mm rail mounting.
• Coil rated for 24 V AC, 50/60 Hz, with low power consumption of 5.5 VA.
• Silver nickel contacts for long electrical life.

In daily use

The relay is controlled by momentary push-buttons: each pulse toggles the contact state. This allows multiple control points without complex wiring. The mechanical indicator shows the current state, and the relay can also be manually operated via the lever on the front.
