This is a set of 2 effector footswitches. They are CLIFF FC71077 type 3PDT footswitches. These are leftovers from when I tried to mass-produce DIY effectors. They are being sold at a bargain price. They can be used for footswitches on guitar and bass effectors, etc. <Specs> Shaft diameter: 12mm Total length: 42mm (including terminals) There is a large stock, so they are sold as a set of 2. Bulk purchases are possible.
