NKK Switches FD01 & FD02 Ultra-Thin DIP Rotary Switches

NKK Switches FD01 and FD02 Ultra-Thin DIP Rotary Switches are ultra-thin DIP rotary switches with compact dimensions (7.2mm² or 7.7mm² with a 3.1mm to 3.3mm height) for high-density mounting. NKK FD01 is a through-hole terminal model with standard inch grid spacing, and FD02 is a surface mount (gull-winged) terminal model that secures mechanical stability even during soldering. The internal construction of these rotary switches incorporates metal springs for smooth, crisp operation. Applications include factory automation, robotics, handheld automation devices, communication devices, measuring devices, and audio equipment.
