The chain to toggle switch connection for auto cut-off fix.

On a couple of different saws, I needed to connect a 20 amp toggle switch to a chain connected to the vice sled to produce an auto-cut-off for when the saw was neglected. I found that the expanded end from an oxygen cannula (hey we all know someone who has to use oxygen and has dozens of extra tube sets) fits snuggly over the toggle on the electrical switch. By cutting off that plastic fitting and an short length of the oxygen hose, I not only extended the length of the toggle, but also produced a soft end which was easy to perforate for attaching a stiff wire intended to run from the toggle switch to the chain inside my saw tank, where the wire attaches to a chain and the vice sled. On one saw I had to drill a small hole for the wire to enter the tank, the other had a convenient hole in the tank. The soft rubber cannula fitting is easy to slide off of the toggle when more slack is needed, but the length of the trip wire is adjusted on the other end close to the vice. I'll add a photo for those more visually oriented (tomorrow when I'm back in my work clothes - headed for an outdoor concert and have my public attire on at present).

Just to complete the story here's how the arrangement looks and is wired.
In the spirit of recent questions about cutoff switch wiring:
In brief the hot wire on the outlet cord goes through two switches. The cut-off switch is normally left closed except when opened by the wire/chain vice position activation. The on and off of the saw is accomplished with the first switch (a heavy duty household style switch). Works great especially since I try very hard not to abandon my saw to the auto-cut-off option.
