Well,
that switch looks like industrial motion switch made by Allen Bradly or Square "D"
They prolly decided to use an off the shelf switch rather than design and manufacture their own version for such a small production run of baggers.
You might find something surplus like it on ebay if you want to take the time.
Or find something like a seat switch or clutch switch for a cub or a waterproof toggle switch and steal the rubber condom from it.
Speaking of condoms, 'pose they would work also. just make sure you mention
it to the wife FIRST, so she don't put your pillow in the dog house, or call a divorce lawyer.
---Might be more costly than that a new switch.
