Safety switch for home made machines

[Karl_H]

My version:











I need to add a spring like Christophe did since mine will occasionally turn itself off if there is too much vibration in the saw.

The box, switch and hinge are readily available at the big box stores or any hardware store. The paddle is just a scrap of wood with a hole drilled through it.

You might need to add a small block to contact the "Off" side of the switch if your hinge isn't just right
