Fangrui Product Details 1. The Resistor Board Uses 0. Precision Resistors, Not Ordinary Resistors. 2. The Resistor Is Plug-in, Not Patch. The Distance Between The Two Pins Of The Patch Is Small, Moisture Makes The Resistance Value Smaller, And The Stability Is Poor. 3. Instead Of Using A Dip Switch, A Gold-plated Pin Is Used.

The Contact Resistance Of The Gold-plated Pin Is More Than Half Smaller Than That Of The Dip Switch.
