Product description
This Siemens mushroom pushbutton, part number 3SU1050-1BA30-0AA0, features a large 40mm yellow head and operates with a latching mechanism that is released by pulling. It has a 22mm round metal body with a shiny finish.
This type of pushbutton is commonly used for functions that need to be activated and stay in that state until intentionally released, such as a power on/off switch or a specific mode activation. The large size and latching action make it suitable for operator panels requiring clear engagement.

Frequently asked questions

The 'pull-to-unlatch' mechanism on the Siemens 3SU1050-1BA30-0AA0 means that when the button is pushed, it locks in place, maintaining its state (e.g., circuit closed). To return it to its original position, the user must pull the button outward.
