High-brightness illuminated tactile switches for reflow soldering uses introduced by Littelfuse

Summary points:

• Littelfuse introduces the K5V4 family, designed for manufacturers switching from wave to reflow soldering processes.
• Built with high-temperature polyarylate material, these switches eliminate the need for silicone sleeves, reduce production costs, and support high throughput.
• Offers sharp tactile feedback, integrated high-brightness LEDs, and gold-plated dome contacts for improved functionality and reliability.

ROSEMONT, Ill. – Littelfuse Inc. in Rosemont, Ill., is introducing the K5V4 illuminated tactile switches for manufacturers switching from wave to reflow soldering processes.

The K5V4 family of illuminated tactical switches include the gull wing and 2.1-millimeter pin-in-paste versions, which are compatible with reflow soldering.

The switches are built using a high-temperature polyarylate material with a 250-degree-Celsius thermal deformation threshold. By eliminating the need for silicone sleeves or special handling and enabling SMT assembly, they can help reduce production costs, support increased throughput, and improve end-product quality.

Key features

Key features and benefits include reflow soldering-compatibility; contact configuration with normally open and normally closed options; sharp tactile response with audible click; integrated high-brightness LEDs; and gold-plated dome contacts.

The high-brightness tactile switches are available in tape and reel format, with quantities ranging from 1,000 to 2,000 units. For more information contact Littelfuse online at www.littelfuse.com.
