The 4×4×1.5mm 2-Pin SMD Tactile Switch is an ultra-low-profile momentary push-button switch designed for compact electronic devices and high-density PCB layouts. With its slim 1.5mm height and compact 4×4mm footprint, this switch is ideal for applications where space is limited and a low-profile design is essential.

Operating in a normally open (NO) configuration, the switch completes the circuit only when pressed and automatically returns to its open state when released. Its surface-mount design supports automated assembly processes and provides reliable tactile feedback, making it suitable for consumer electronics, wearable devices, mobile accessories, IoT products, and embedded systems.

Key Features

  • Ultra-low-profile 4×4mm footprint with 1.5mm height
  • 2-pin Surface Mount Device (SMD) design
  • Momentary ON (Normally Open) operation
  • Crisp tactile feedback for precise user input
  • Ideal for slim and compact electronic products
  • Compatible with automated SMT assembly
  • Durable construction with reliable performance
  • Suitable for wearables, IoT devices, and portable electronics

FAQ

1. What is a 4×4×1.5mm 2-Pin SMD Tactile Switch used for?

It is used as a momentary input switch in compact electronic devices such as wearables, remote controls, mobile accessories, IoT products, and embedded systems.

2. How does the 4×4×1.5mm tactile switch operate?

It works on a normally open (NO) mechanism, completing the circuit only when the button is pressed and returning to the open state when released.

3. Why is the 1.5mm height important?

The ultra-low-profile 1.5mm height makes the switch ideal for slim and space-constrained electronic products where PCB height is a critical factor.

4. Is this switch suitable for automated PCB assembly?

Yes, its Surface Mount Device (SMD) design is compatible with automated pick-and-place and reflow soldering processes used in electronics manufacturing.

5. Can this switch be used in custom PCB and microcontroller projects?

Yes, it can be integrated into custom PCB designs for Arduino, ESP32, STM32, and other embedded systems that require a compact tactile input switch.
