Schneider Electric XB6CW4B2B Harmony XB6 Illuminated Red Square Flush 16 mm Spring Return 1NC Push Button

The Schneider Electric XB6CW4B2B is a Harmony XB6 complete illuminated push button with a red flush square head, 16 mm plastic bezel, spring-return operator, and 1NC slow-break contact, supplied at 12...24 V AC/DC. The square head distinguishes it visually from the round XB6AW4B2B on the same panel, mounting into the same 16 mm cut-out.

Selection Notes

The square head is a shape-coded alternative to the round XB6AW4B2B for the same electrical function. The 1NC contact opens on actuation, so this button suits a stop or interlock-break command rather than a start signal, unlike the 1NO XB6CW1B1B and XB6CW3B1B. Red follows IEC 60073 colour-coding for stop or fault-related commands. Running on 12...24 V AC/DC with only 15 mA draw, the integral LED shares the same low-voltage control supply as the contact.
