rare pair of old early electric, industrial circuit breaker switches w/ mica fuse sockets & fuses, 1800s patents

Pair of rare antique, very early electrical, architectural or industrial fused breaker knife switches and three antique mica faced fuses. These breakers are marked "Paiste" and are rated for 30 amps and 125 volts. They have heavy white ironstone porcelain base and screw in fuse sockets on each line. The fuse sockets are standard Edison bases with mica bottoms and would also accept light bulbs (as well as the fuses) and so these would be great to display a collection of antique and early light bulbs.

These antique architectural or industrial circuit breaker switches measure about 5 1/8" x 3" across the porcelain bases.

The antique architectural screw fuses all have mica windows and early patent dates. One of the fuses is marked General Electric and is marked with patent dates Oct 6 1891 (just 12 years after Thomas Edison received his patent on the light bulb and five years before Harvey Hubbell was issued his patent on the pull chain switch electric lamp socket) and Feb 9, 1897. The other two fuses are General Electric (we think), but we can't make out all of the names and patent dates on the fuses that are marked "12" and didn't want to damage the excellent patina).

These all have a great patina of age to the brass and copper switch blades and terminal parts... a must have for any collector of early and antique electrical fittings!
