Can someone recommend a source for a replacement power
switch?
It is a toggle type snap switch for an Optonica SM-1515B
stereo amp. Hole spacing is 1-3/8 inch. 120V.

Looks to me like a fairly generic paddle switch.

It was probably marketed under the brand name "Panasonic". It may be a stock
design.

If you're looking for an exact replacement, here are some places to look:

(1) Authorized parts sellers for the brand of equipment you are trying to
repair.

(2) Distributors for the brand of part, in this case Panasonic.

If you're looking for an near replacement, here are some places to look:

(1) Electronic parts catalogs for places like Newark, Digi-Key, and Mouser.

(2) Surplus and remainering houses like Jameco, All Electronics and Parts
Express.

You are looking for a part with the same number or more contacts, with
contacts rated at the same or more amps and volts, and one that is the same
size or smaller. Mounting centers should match or be smaller.

Your replacement strategy may include fabricating a sheet metal bracket that
bridges any possible gaps.
