Siemens 3SB365-0AA21 Pushbutton Switch Illuminated

Siemens 3SB3650-0AA21 Illuminated Pushbutton combines a 22 mm round metal housing with a red flat actuator, a lampholder, and an integrated LED to provide visible status in panel-mounted control circuits. It features a single normally closed (1NC) contact configuration and wiring via screw terminals, rated for 110 V AC/DC operation. The rugged metal construction and bright red button enable clear signaling in machine controls, safety interlocks, and other panel interfaces where an illuminated indicator is required. This unit is part of Siemens' 3SB family of illuminated pushbuttons, designed for compact, durable operation in industrial environments.
