Description

Overview

The Siemens 3SU1050-1BD20-0AA0 is a high-quality component from the SIRIUS ACT range, designed for robust and reliable industrial control applications. This mushroom pushbutton features a striking red, shiny, and durable metal enclosure that ensures longevity and high visibility in critical situations.

It is engineered for a standard 22 mm mounting hole and boasts a large 40 mm diameter head, making it easy to operate, even with gloves. The unit utilizes a momentary contact type function, meaning the circuit is closed only while the button is actively pressed. Ideal for applications requiring immediate, but not sustained, operation.
