Hey, if the power switch on your Hitachi circular saw or miter saw is acting up or broken, this is the exact replacement part you need! This is a pack of four genuine Hitachi switches, model number 324424. They're the fasten type without a lock, designed specifically for Hitachi models C12LSH, C12RSH, C8FSE, and C8FSHE (the tools themselves aren't included, just the switches). Before you buy, double-check your tool's model number and maybe take a peek at the parts diagram to make sure this is the right switch for your saw. Super straightforward to swap out if you're handy. It's always smart to use official Hitachi parts to keep your tool running smoothly and safely. The country of manufacture might vary, but the quality is what you expect from Hitachi. Get your saw back in action!
