Product description

The Siemens 3SU1000-0AA40-0AA0 is a 22 mm round pushbutton from the SIRIUS ACT lineup, featuring a flat actuator design and a vibrant green color. This pushbutton is designed for latching operation, meaning it stays engaged after being pressed and requires a distinct 'push-to-release' action to return to its default state. Constructed from durable plastic, it is suitable for various industrial environments.

This pushbutton is ideal for control panels and operator interfaces where a clear visual indication and a latching function are required, such as start/stop controls, mode selection, or status indicators in machine controls, building automation, and process industries.

Stanlo Automation, a veteran-owned surplus distributor, offers the Siemens 3SU1000-0AA40-0AA0. Find reliable and cost-effective components for your control system needs from a trusted source.

Frequently asked questions

What is the difference between latching and momentary pushbuttons like the 3SU1000-0AA40-0AA0?

A latching pushbutton, like the 3SU1000-0AA40-0AA0, stays in its pressed state after activation until it is manually released (in this case, by pushing it again). A momentary pushbutton only remains active while the button is being held down.
