Product Description
RS PRO 111-3897 Illuminated Push Button Switch features a robust momentary action mechanism, designed for durability and high reliability in both industrial and professional applications. The switch is intended for panel mounting, utilizing a 19.2 mm cutout for quick and secure installation in control systems, panels, and enclosures.
This push button model provides a single pole double throw (SPDT) contact arrangement, enabling control versatility for a range of electrical circuits. The actuator is crafted in silver, offering a modern aesthetic as well as superior electrical conductivity thanks to silver-plated copper contacts. With a round actuator style, ergonomics are enhanced for frequent repetitive use.
Blue LED illumination provides clear indication of switch status, making it highly visible in operation. IP67 rating certifies resistance to water and dust ingress, ensuring reliable switching in harsh environments. Compatible with both 12 V DC and 250 V AC input voltages, making integration with common control and automation systems straightforward.
Momentary action supports applications where switching is required only while the button is pressed, preventing accidental latching. Switch configuration of 1 NO/1 NC maximizes circuit design flexibility. Rated for a contact current of 5A, supporting typical industrial loads.
This push button switch is commonly used in machinery operation panels, HVAC control stations, communications equipment, and medical devices. Its short body design is optimal for installations in space-restricted applications, while the solder-type terminals allow for fast and secure electrical connections during assembly.
The RS PRO 111-3897 push button is a professional solution for demanding settings where reliable manual control input and status indication are required. Its IP67 ingress protection, wide temperature compatibility (-20°C to 55°C), and compliance with UL 94-V0/V2 flammability standards confirm its suitability for challenging installations.
