Securing a very, very old 220V switch
Condgratulations, you are now the owner of a finger eating machine, the saw table is the main reason why so many old carpenters have fewer than 10 fingers. But being motivated to make this purchase probably know that already.
I would seriously consider replacing that rocker switch with a proper emergency stop button. you could probably convert that rocker switch by putting a hinged panel in front of it with a hole for &quot;on&quot; and the whole panel for off.
You should definately replace those spade connectors with insulated spade connectors, your plan of using using heatshrink to upgrade them
to insulated is a good way to do that.
Mount the switch to a proper panel, I don't see a mounting panel, but perhaps you removed it to take the photo.
if you disconnect the neutrals from the switch use a male-male spade joiner, or a proper splice connector to join them together.
