Difficult to find, old style fixtures.
Trying to find a 3 terminal, 3 way light fixture is virtually impossible. I had to settle for a 3 terminal E-26 light bulb socket, and had to order a separate switch to take care of the problem of getting both features in one unit. I found a 3 way switch that hopefully will work with a 3 terminal light bulb fixture. Don’t yet know if it’ll work, but hopeful.
