    Different Kind Of 3 Way Light Bulb Switch

    Fixing a lamp, I have a strange light bulb socket, at least strange to me.

    It's a 3 way but not to a 3 way bulb. Way one, primary bulb on. Way two, second base bulb lights up but not primary. Way three, all off.

    It needs to fit standard (1/4"?) lamp post pole threading and take an E27 bulb. Am I just not using the right search terms? This is replacing a failed (worn out and severely corroded) socket that does not have more than a two way bulb contacts in the socket.

    can you still get multi-way bulbs with the constant push to cfl or led lamps?

      Not relevant. I am asking about 3 way where the 3rd way is a separate bulb ( circuit ) instead of a separate ring on the same bulb socket. Whether it is LED or not is irrelevant, but yeah, it makes sense to make both bulbs LED.

        so actually a cluster of 3 holders?

            ^ Yes. I need it to do that, and have a rotating side stem switch like this:

            https://www.amazon.com/gp/product/B002DN4LX4

            If it comes with the exterior shell like that one at amazon, it'll have the (1/4"?) threaded mount on the bottom that is needed, or I could reuse the old exterior shell if I found the interior switch/socket assembly sold separately.

            Previously I wrote E27 but I meant E26, need E26 socket.

            Did some more searching, found a lamp repair site that stated I have a "3 terminal" socket. Think I found what I need with this:

                ^ No you had it right the first time. I bought the PLT 90-421 that I linked on Amazon. Oddly 1000Bulbs sells it with $2.29 shipping on Amazon but wants $10 shipping if ordered direct from their website.

                Leviton also makes one that looks right as # 07070-0PG

                      3 way switches have so many different connotations.

                      One is the typical light fixture that uses a 3 way bulb with two filaments and the 3 way switch can select either one or both of the filaments. "Rotary Encoder" HAHAHAHAHA

                      It also can refer to a SP3T switch, which is what the OP wants.

                      It also can refer to the XOR house lighting dual SPDT switches that can turn on and off a lamp from two locations...

                      I think the SP3T switch or "SPDT with off position" is non-ambiguous here... though finding them can be tricky.

                            I am not referring to the OP requirement since the one he needs is available.

                              Yeah but this is a fancy antique lamp with its own matching stem handle that screws onto the switch shaft in place of the original plastic one. I thought about converting it to a capacitive touch lamp but decided cheap, quick, and easy would result in me more likely getting it back to the owner soon instead of shelving the project and forgetting about it. Besides it still needs a new socket even if it had capacitive switching. I tore the old one open to see if it was refurbish-able but it was just too worn out.

                              This is how little I know about lamps. The lamp has a standard 1/8 threaded IPS (internal pipe size), 3/8" O.D. pipe, what practically all modern lamps have so I'm good there. Previously I was just guessing 1/4" without giving it much thought because I knew it looked standard.

                                Received socket today and replaced it... took longer to post these pics than to do it, lol.

                                Nothing special involved, screws, middle terminal is socket for each bulb, AC neutral, and the two opposing side terminals, one is AC hot and the other goes to the other bulb socket center conductor.
