Micro-Miniature Surface Mount Tactile Switch 4.6×3.2mm

This Micro-Miniature Tactile Switch offers a compact, high-reliability switching solution designed for space-constrained PCB assemblies. With a miniature outline of just 4.6mm x 3.2mm and a low-profile actuator height of 2.5mm off the board, this top-actuated component is ideal for portable electronics, wearable devices, and dense control panels where real estate is at a premium.

Engineered for precision and durability, the switch features a positive tactile feedback mechanism, ensuring a crisp actuation feel for end-users. It is available in two distinct operating force options to suit different application requirements: a light-touch 160gf variant for rapid, low-fatigue operations, and a firm 250gf variant that provides a more deliberate click to prevent accidental presses in high-vibration environments.

The electrical rating is rated at DC 12V 50mA, making it suitable for low-power digital logic circuits and microcontroller inputs. The termination style utilizes J-Hook leads, which provide a robust surface-mount solder joint with enhanced mechanical strength and excellent resistance to shear stress, ensuring a secure connection throughout the product’s lifecycle.

Form, Fit, and Function Equivalency:
This switch is designed to be a direct physical and electrical replacement for industry-standard components. It maintains identical dimensions and specifications to the Alps Alpine SKRP series, specifically cross-referencing models SKRPABE010 (160gf), SKRPACE010 (160gf), SKRPADE010 (250gf), and SKRPARE010 (250gf). Furthermore, it is entirely footprint-compatible with the C&K PTS810 Series, including the PTS810SJG250SMTR LFS, PTS810SJK250SMTR LFS, PTS810SJM250SMTR LFS, and PTS810SJS250SMTR LFS variants. This cross-compatibility allows for seamless integration into existing designs, providing secondary sourcing flexibility without requiring PCB layout modifications.
