Multiple Heights Available: 4×4×1.5mm, 4×4×2.0mm, 4×4×2.5mm, 4×4×3.0mm, 4×4×3.4mm.
Surface-Mount SMD Design: Suitable for reflow soldering and high-volume PCB assembly.
Momentary Normally-Open Action: Closes circuit only when pressed.
Low-Profile & Compact Size: Ideal for dense PCB layouts and slim device housings.
Reliable Tactile Feedback: Crisp click response for durable operation.
Wide Electronic Compatibility: Used in consumer electronics, IoT devices, and embedded systems.
The 4×4mm SMD Tactile Switch series is designed for compact PCB applications requiring reliable momentary push-button control. Available in multiple height variations ranging from 4×4×1.5mm up to 4×4×3.4mm, this switch accommodates different board and enclosure depth requirements.
Featuring normally-open momentary operation, the switch closes only while pressed, making it ideal for power, reset, and function buttons. Its SMD terminal design supports automated production with stable reflow soldering and surface-mount PCB attachment.
This tactile switch series is widely used in consumer electronics, sensor modules, remote controls, IoT devices, and embedded control systems. The durable contact structure provides long mechanical life, consistent actuation force, and reliable tactile feedback.
