Hager WNC027 Push Button Switch, 1-Pole, 1 N.O., 10A, 250V AC, DIN Rail, Light Grey

The Hager WNC027 is a momentary push button switch engineered for DIN rail mounting, offering a compact 1-module width that saves valuable space in distribution boards. Unlike toggle switches, its push-to-make action returns to the off position when released, making it ideal for signaling, bell circuits, or control applications where a brief contact closure is required.

Highlights

• 1-pole, 1 normally open (N.O.) contact configuration
• Rated current 10 A at 250 V AC, 50/60 Hz
• Screw terminals accept rigid conductors 1.5–4 mm² and flexible conductors 1.5–2.5 mm²
• Operating temperature range -20 °C to +50 °C
• Thermoplastic housing in light grey

In daily use

Installation is straightforward on a standard DIN rail, and the screw terminals provide a secure connection for building wiring. The momentary action ensures the circuit is only energized while the button is pressed, reducing the risk of unintended continuous operation. With an electrical endurance of 30,000 cycles and mechanical endurance of 100,000 cycles, the WNC027 is built for frequent use in residential and commercial control circuits.
