This switch will work in most benchtop machines on the market. The opening size is 19mm (.755) X 34mm (1.342). The switch is rated 20-12A on 125/250VAC. The yellow safety button pulls out so the tool cannot be turned on. The bigger paddle style switch is easier to find and turn off. Shipping on this item is free. I do ship internationally, just email me your location and I will quote shipping to your country.
