Illuminated flush-mount button BSP yellow 2 NC, 1 NO AC(24 V-230 V),DC(24 V-110 V) "STOP" SP22-AKLG-21-LED.UNI\AC/DC-3

Illuminated control button – reliability and functionality in every circuit

This BSP illuminated push button, in yellow color, is a solid solution for controlling electrical circuits. Designed for both professional and end-user applications, it provides safe and convenient operation for switching devices on and off. It has two normally closed contacts (2 NC) and one normally open contact (1 NO), making it a versatile element in electrical installations. Compatible with AC (24 V - 230 V) and DC (24 V - 110 V) voltage, it offers flexibility in selection for specific needs.

Construction and application

This button is characterized by high resistance to external conditions thanks to the IP65 protection rating. This means it is dustproof and protected against a low-pressure water jet, allowing it to be used even in harsh industrial conditions. The round lens shape and the front ring made of plastic ensure durability and aesthetic appearance. The mounting hole diameter is 22 mm, and the width is also 22 mm – a standard dimension that facilitates the replacement of existing buttons.

The button finds application in a wide range of devices and machines, such as:

• Control panels
• Industrial automation
• Lifting equipment
• Construction machinery
• Electrical installations in buildings

Operating parameters and safety

The design of this button is designed for long-term and safe operation. The continuous rated current Iu/Ith is 10 A, and the rated switching current in category AC-15 is 2.5 A at 230 V and 1.6 A at 400/500 V. In category DC-13, the button withstands a current of 4 A at 24 V, 1 A at 110 V, and 0.25 A at 220 V. Short-circuit protection of the switching elements requires the use of a 10 A (fast) fuse. The mechanical durability is as much as 3 million switching cycles, and the switching durability is at least 200,000 cycles at rated parameters. The button meets the standards PN-EN 60947-5-1 and IEC 60947-5-1 and IEC 60947-1, which guarantees its compliance with European safety standards. Additionally, it is resistant to vibrations and mechanical shocks. The power of the LED lamp is up to 1.6 W (LED UNI), which provides clear illumination even in low light conditions.
