Most of my wedgeheads have ... a on off switch installed since . im sure some would disagree with drilling into the bottom board , but it is a great convenience to do and relatively easy. here are some images. the thing to do is to .. drill a bottom hole near the front of the machine., with a block with same size hole inside. . have a matching size of wood" plate to drill and install toggle switch . then carry 2 wire from toggle switch back to lead fuse. disconnect wire from lead fuse to one end of wire coming from toggle switch . the other strand to the lead fuse.
The purpose of the block is to .. keep the toggle safe when moving or sliding the machine when transporting it is beneath the level of the bottom board.
