Red mushroom button 1 NC, 2 NO, nickel-plated ring ST22-DC-12. ST22-DC-12\.

Mushroom button – a reliable control and signaling element

This red mushroom button, designated ST22-DC-12, is a solid and functional element designed for use in control and signaling applications. It is characterized by high reliability and durability, making it an ideal choice for both professional installers and end-users. The construction with a nickel-plated ring adds to its aesthetic appearance and resistance to mechanical damage.

This button is designed for mounting in holes with a standard diameter of 22 mm, ensuring easy integration with various control panels and machine housings. Its self-resetting design guarantees immediate operation after release, which is crucial in applications requiring a quick response. The IP65 protection rating provides resistance to dust and water jets, allowing for safe use even in harsh industrial conditions.

Construction and parameters ensuring versatility

The button is equipped with one normally open contact (1NO) and two normally closed contacts (2NC), allowing it to be used in various electrical circuit configurations. Screw connection ensures a secure and durable connection of wires. The front ring made of high-quality plastic in gray color increases its resistance to external factors. The round shape of the lens provides good visibility of the button status. Since the button does not have backlight capabilities, the focus has been on its primary function – reliable control of electrical circuits.
