Product description

The Siemens 3SB3203-0AA11 is a 22mm round, black pushbutton featuring a flat button design and plastic construction. This complete unit combination includes one normally closed (NC) contact, connected via screw terminals, and comes with a holder. It is designed for control applications where a normally closed contact is required. This is a phased-out product, with the SIRIUS ACT 3SU1 series as its successor.

This pushbutton is used in industrial control systems where the circuit needs to be broken when the button is pressed. Applications include stopping mechanisms, safety interlocks, or circuits that are 'on' by default and require an operator action to interrupt. It is commonly found in manufacturing and automation equipment.
