The push button switch on my mill/drill gave up the ghost today. In looking for replacements they are $50 or more from a US supplier like McMaster Carr or $5 from China on Ebay and who knows when I would get. Any reason why I can't use a good quality toggle switch from my local hardware store? The broken switch is a 15 amp switch. I am in the middle of a project and need to get my mill/drill working. And I never buy anything from Amazon.
