Product description

The Siemens 3SB3 647-0AA21-0CC0 is a 22mm metal round complete unit, featuring an illuminated momentary pushbutton with a flat button design. It integrates an LED for illumination at 24V AC/DC and includes a holder with one normally open (NO) and one normally closed (NC) contact. The terminal type is spring-loaded. This is a phased-out product, with SIRIUS ACT 3SU1 being its successor.

This illuminated pushbutton is used in control panels and machinery for operator input and status indication. It's ideal for applications requiring both manual control and visual feedback, such as motor control centers, process automation, and material handling equipment.

Stanlo Automation, a veteran-owned surplus distributor, offers the Siemens 3SB3 647-0AA21-0CC0. While this item is phased out, we can provide this part or assist in finding suitable replacements from the newer SIRIUS ACT 3SU1 series.
