Flush-mount button BSP yellow 1 NC 1 NO nickel-plated ring ST22-AKG-11. ST22-AKG-11\.

Control button – reliability and durability in every application

This yellow control button, designated ST22-AKG-11, is a robust component designed for building control panels and devices requiring reliable starting or stopping of processes. The construction with a single normally open and normally closed contact, combined with a nickel-plated ring, ensures both functionality and aesthetic appearance. This button finds application in a wide range of industries – from industrial automation, through lifting equipment, to machines and special-purpose devices.

Construction and characteristic features

The button is characterized by a flat design with a round lens, which ensures comfortable use and easy integration with the panel. Mounting is done in a 22 mm diameter hole, and a solid screw connection guarantees safe and stable connection of wires with a cross-section of 1…2.5 mm² (solid) or 0.75…1.5 mm² (stranded). The front ring made of high-quality plastic adds durability and resistance to mechanical damage. The IP65 protection class provides protection against dust and water jets – an ideal solution for industrial environments.

Application and benefits

The ST22-AKG-11 button has been designed with demanding applications in mind. Non-latching (without self-return) means that the button remains in the closed or open position until pressed again – which is particularly important in applications requiring state maintenance. Compliance with PN-EN 60947-5-1 and IEC 60947-5-1 standards guarantees safety and reliability of operation. Additionally, resistance to vibrations and shocks (according to IEC 60068-2-6 and IEC 60068-2-27) makes the button perform perfectly in harsh working conditions. It is also worth mentioning the wide operating temperature range (-40°C to +70°C), which allows its use in various environments.
