Safety switch for home made machines
No, this is not a bird nest for the garden !
This is a very simple (who said crude ?) but efficient mechanism which provide safety for starting and stopping any shop build machine.
Here, this is a router table.
The principle is to use a standard rocker switch (16A) and to build a sort of cage around it, with a swivelling cover that falls down by gravity.
Under the cover, there is a small pad glued to it, which can press the rocker switch to turn it off.
A hole is drilled in the cover in order to pass your finger and turn the machine on.
There is a spring that keeps the cover away from the rocker switch, so that the sole weight of the cover can not turn the machine off.
(here, spring taken from a cloth pin)
