Safety button – reliable control and protection

This red safety button with a nickel-plated ring, designated ST22-B-12, is an element designed for applications requiring precise control and safety. It is a mushroom-shaped actuator that remains locked (non-self-returning) when pressed, ensuring the signal state is maintained until deliberately released. The construction and materials guarantee durability and resistance to harsh industrial conditions.

Construction and application

This button is used in various devices and control systems where safe starting or stopping of processes is required. It features a screw connection, which simplifies installation and integration with existing electrical installations. A mounting hole diameter of 22 mm makes it compatible with most standard control panels. The red button color and gray front ring made of plastic ensure good visibility and compliance with safety standards.
