Siemens SIRIUS ACT Mushroom Pushbutton Front Element, Plastic, Black, 22mm, 40mm Actuator, Latching, Pull-to-Unlatch 3SU1000-1AD10-0AA0

Industrial control panels often need a highly visible, robust emergency stop or stop function that can be operated quickly and reliably, even with gloves. The Siemens SIRIUS ACT mushroom pushbutton front element provides a large 40 mm actuator in black plastic, designed for 22 mm mounting holes and latching operation with pull-to-unlatch. It is part of the modular SIRIUS ACT system, allowing combination with various contact blocks and holders.

Who is it for

Panel builders, machine OEMs, and maintenance technicians who need a durable and clearly identifiable mushroom pushbutton for control circuits in industrial environments. It suits applications requiring a stay-put stop or emergency stop function where a twist or pull release is preferred.
