Product description

The Siemens 3SB3000-1AA20 is a 22mm plastic round mushroom pushbutton actuator with a 60mm head. This red actuator features a latching (maintained) function and is designed for twist-to-unlatch operation. It requires a separate holder and is part of the phased-out SIRIUS 3SB3 series, with the SIRIUS ACT 3SU1 series as its successor.

This large, red mushroom pushbutton is commonly used for emergency stops or critical stop functions in industrial machinery due to its prominent size and immediate visual cue. The twist-to-release mechanism is a standard safety feature.
