Button actuator - 2-gang white/black nickel ring ST22-2KLB/CZ. ST22-2KLB/CZ\.

Pushbuttons – reliability and functionality in every circuit

This control button drive, designated ST22-2KLB/CZ, is a component designed for mounting in control and signaling circuits. It is an element used to start, stop or change the operating state of electrical devices. The design with two keys allows operation of two independent functions, which increases its versatility.

This drive finds application both in industry and in commercial and residential construction. It will be useful in control panels, machines and devices where reliable and intuitive operation is required. Thanks to the IP65 protection class, it is resistant to dust and water ingress, which allows it to be used in harsh environmental conditions.

Construction and user features

The ST22-2KLB/CZ drive is characterized by a solid construction and thoughtful design. Made of high-quality plastic and finished with a chrome front ring, it looks aesthetic and ensures durability. The self-returning mechanism ensures comfortable use - after releasing the button, it returns to its original position.

• Two keys: allow operation of two independent functions in one device.
• Self-returning mechanism: ensures comfortable use and quick response to operator commands.
• IP65 protection class: guarantees resistance to dust and water ingress, which increases durability and reliability in harsh working conditions.
• Chrome front ring: gives an aesthetic appearance and protects against mechanical damage.
• Oval lens shape: improves readability and identification of buttons.
• Intended for holes with a diameter of 22 mm: facilitates mounting in standard control panels.

It is also worth mentioning the electrical parameters of this drive: the continuous rated current is 10A, and the switching current in the AC-15 category is 2.5A (at 230V) and 1.6A (at 400/500V). Short-circuit protection of the connector paths is 10A (fast fuse insert). The mechanical durability of the drive is as much as 3 million switching cycles, which guarantees a long service life even with intensive use.
