Double-button switch 1 NO 1 NC green-red AC ST22-2KL-11-230-LED\Z/C

Double-key button – reliability and functionality in every circuit

This double-key button from Spamel, designated ST22-2KL-11-230-LED\Z/C, is a robust solution for controlling electrical circuits. Equipped with two independent contact sets – normally open (NO) and normally closed (NC) – it provides versatility for use in various installations. Red-green LED signaling facilitates visual identification of the circuit status, which is particularly useful in alarm systems, control panels, and operator panels.

Design and user parameters

The button is designed for durability and resistance to harsh working conditions. Its round lens and housing made of durable plastic provide protection against mechanical damage and environmental impact. The IP65 protection rating guarantees resistance to dust and water jets, allowing safe use even in humid or dusty environments. Mounting is done in a standard 22 mm diameter hole, which simplifies integration with existing panels and enclosures.

The button is characterized by high electrical parameters: the continuous rated current is 10A, and the switching current in the AC-15 category is 2.5A at 230V. This allows it to be used to control various loads, such as motors, heaters, or lighting. Additionally, high mechanical durability (3 million switching cycles) and switching durability (0.2 million cycles at rated voltages and currents) ensure long and trouble-free operation of the device. The built-in 1W LED lamp (operates at 230V AC) further increases the functionality of the button by providing optical signaling of the circuit status.

Application and compliance with standards

The Spamel ST22-2KL-11-230-LED\Z/C button finds application in a wide range of electrical installations – from simple control systems to advanced industrial automation. It is ideal for building control panels, machines, and devices requiring a reliable and intuitive user interface. It meets the requirements of PN-EN 60947-5-1 and IEC 60947-5-1 and IEC 60947-1, which confirms its safety and compliance with applicable standards.
