Double-button switch 2 NO 1 NC green-red SP22-2KL-21-24-LED\Z/C

Double-key illuminated push button – a reliable control element

This double-key control button, with a diameter of 22 mm, is a solid and versatile solution for various applications. Its design combines functionality, durability and ease of installation. It is ideal for both modern industrial installations and more demanding applications.

Construction and application

The SP22-2KL-21-24-LED\Z/C button is designed for mounting in 22 mm diameter holes. It has two normally closed and one normally open contacts, allowing for flexible configuration of control circuits. The high-quality plastic front ring provides resistance to mechanical damage, and the round lens shape guarantees clear visualization of the button status. The IP65 protection class protects against dust and water, enabling operation in harsh environmental conditions.

Key features and benefits

• Durability and reliability: The button is designed for intensive use, offering high mechanical (3 million switching cycles) and switching durability (0.2 million cycles at rated parameters).
• Versatility: Two normally closed and one normally open contacts allow for the implementation of various control schemes.
• Resistance to external conditions: IP65 protection class ensures safe operation in dusty and humid environments.
• Wide voltage range: Possibility of use with LED lamps or traditional bulbs with a voltage of 24 V or 230 V AC/DC. Lamp power is 1W (LED) or 2W (bulb).
• Safety: Compliance with PN-EN 60947-5-1 and IEC 60947-5-1 standards guarantees safe operation of the device. Short-circuit protection of the connector tracks is 10A (fast fuse) or 1kA (expected short-circuit current for Ue=500V).
• Easy installation: Adapted for wires with a cross-section of 1…2.5 mm² (solid) or 0.75…1.5 mm² (stranded). The operating position is arbitrary and the terminal marking is in accordance with PN-EN 50013.

Electrical parameters – what you should know

The button is characterized by a rated continuous current of 10A and a rated switching current depending on the load category:

• AC-15: 2.5 A (at 230 V) and 1.6 A (at 400/500 V).
• DC-13: 4 A (at 24 V), 1 A (at 110 V) and 0.25 A (at 220 V).

The rated insulation voltage is as high as 500V. The device is resistant to vibrations and mechanical shocks in accordance with IEC standards.
