The K5V4 models are the latest in the KS5 Series illuminated Tactile Switch range
Littelfuse, an industrial technology manufacturing company, has expanded its KS5 Series illuminated Tactile Switch family with new K5V4 models
The new K5V4 models include the Gull Wing (GH) and 2.1mm Pin-in-Paste versions, compatible with reflow soldering.
Created using a high-temperature polyarylate (PAR) material with a 250°C thermal deformation threshold, the K5V4 switches have been designed to suit manufacturers adopting reflow soldering processes.
No longer requiring silicon sleeves or special handling, and enabling direct SMT assembly reduces production costs, supports increased throughput, and improves end-product quality.
Jeremy Hebras, VP, Switches and Sensors Engineering at Littelfuse, said, “These new K5V4 switches are designed to meet the demands of today’s dense electronic systems, where space efficiency, reliability, and user interface feedback are critical. The K5V switch product series has been created to answer unique customer device architectures where the main board and components are positioned at a 90° angle to the front panel. In combination with long travel, sharp tactile feel, and backlighting, the K5V is ideal when accurate device control is needed, especially where unwanted actuation or lack of immediate user feedback is not acceptable.”
Key features:
- Reflow soldering, compatible via PAR material
- SPDT contact configuration with normally open and normally closed options
