Import Dip Sealed Tactile Switch Wkta1045045a 4.5x4.5mm — Buy in Bulk from Supplier in China

The DIP Sealed Tactile Switch WKTA1045045A is a 4.5mm by 4.5mm surface-mount component with a full travel of 0.25mm ±0.1mm and an operating force range of 1.0N ±0.3N, 1.6N ±0.5N, or 2.6N ±0.5N, depending on actuator design. It operates within a temperature range of -20°C to +70°C and is rated for 50mA at 12VDC. The switch features cambered terminals for self-retention and supports both vertical and horizontal actuation directions, making it suitable for compact PCB layouts in consumer electronics.

The switch is constructed with a sealed housing to resist dust and moisture ingress, and its contact resistance is maintained at 50mΩ or lower under normal conditions. Insulation resistance exceeds 100MΩ, and it withstands 250V AC for 60 seconds without dielectric breakdown. Common heights available are 3.8mm, 4.3mm, 5.0mm, 6.0mm, and 7.0mm, with custom heights adjustable per order. The actuator options include low-profile and high-profile knobs, allowing for ergonomic integration in handheld devices or control panels.

This switch is commonly used in remote controls, medical devices, industrial control panels, and automotive interfaces where reliable tactile feedback is critical. Buyers include OEMs in electronics manufacturing, particularly those sourcing for high-volume consumer goods. Packaging is typically tape and reel or bulk tray, with standard lead times of 2 to 4 weeks. MOQ is typically 1,000 units, but confirmation with the supplier is advised as it may vary by batch.
