4.0 out of 5 stars Works, but not as advertised
By Amazon Customer on July 5, 2019
Bought this to replace a non-working switch. Be aware that if you have an old mercury switch, this one is bigger. See photo as I barely had enough surface to mount the new switch. Also, I ordered the version without the inline fuse, but mine still had the fuse holder. And while the packaging stated it came with a removable base (which would have made installation easier) it did not.
