These Omron V-16-3C5 (.250'' / 6.35mm terminals) are high quality alternative switches for your Sanwa JLF. You will need to purchase four in total to replace the Sanwa JLF switches. Installation on the Sanwa JLF requires the use of the Shuriken JLF PCB.
The effective operating force is 200g, which feel slightly stiff than stock Sanwa JLF switches. Overall these V-16s will make the lever feel snappy, crisp and clean.
