Siemens 3SB3203-1CA21 40mm Push-Pull Button Red
Siemens 3SB3203-1CA21 40mm red push-pull button, pull-to-unlock, 1 NC.
The Siemens 3SB3203-1CA21 is a 22mm plastic round complete unit featuring a 40mm red push-pull button. It offers a latching function with a pull-to-unlock mechanism, requiring a specific action to reset. This unit includes one normally closed (NC) contact, connected via screw terminals, and comes with a holder. This is a phased-out product, with the SIRIUS ACT 3SU1 series as its successor.
This push-pull button is designed for control applications where a distinct visual and physical action is needed to change states, typically for start/stop or on/off functions that require confirmation. The 40mm size ensures high visibility and ease of operation, especially in demanding industrial environments. Applications include machine control and safety systems.
