+FALCOR4 Posted July 11, 2019 Share Posted July 11, 2019 Does someone have a picture showing how the PEB switch is wired for an older push button PEB? This PEB was given to me some 33 years ago in pieces and with no switch. I'm doing a refresh on it (caps, fan, cleaning) to put it back into service. Also, any clever ideas for a switch replacement? Thanks! 1 Quote Link to comment Share on other sites More sharing options...
+FALCOR4 Posted July 12, 2019 Author Share Posted July 12, 2019 Found a picture of the old unit on Thierry's site. That doesn't look like a easy switch to replace. ☹️ Quote Link to comment Share on other sites More sharing options...
+FALCOR4 Posted April 26, 2023 Author Share Posted April 26, 2023 I found a switch on Ebay that seems to be a close fit to the original snap switch that is in the older PEBs. It still has the duplicate contacts on the opposite side of the switch and an end cap that would need to be carefully removed. From the information that @jedimatt42 sent me (thanks!), the original TI switch also had contacts on the opposite side but they were clipped and covered by a plastic shim. Truth in lending, I haven't tried to install it yet but it does look like it might work.

Please keep in mind that I also don't have the bracket to mount it, it was all missing when I was given the PEB years ago. So, probably the best I can do is a crude fit check and to make sure that the switch operates in the same manner as the old switch (ON/OFF part).

The more I look at images I took inside my PEB I'm not convinced the switch will fit on the existing bracket. Am going to try a Kenwood amplifier power switch as it seems to be a pretty good match from the pictures I've seen, won't know for sure until it arrives though Thanks Quote Link to comment Share on other sites More sharing options...
+Atari2600PAL Posted June 27, 2023 Share Posted June 27, 2023 Actually it's a speaker switch, but appears physically identical to my PEB switch. Hopefully it's rated to at least 240v else I've wasted money on it as I can't think what else I'd use it for. Quote Link to comment Share on other sites More sharing options...

+Atari2600PAL Posted July 13, 2023 Share Posted July 13, 2023 Have received the switch. It shows as 250v which seems ok and has the same part E-42153 on it (but I don't know if this is all there is to it) Biggest issue seems to be that it has terminals on both sides, which won't work well with the switch mount plate in the PEB Not sure how to test the switch to see if the terminals are all connected the same as the one in the PEB as I don't know what wire is what. This is going to be fun, not. 1 Quote Link to comment Share on other sites More sharing options...
+FALCOR4 Posted July 13, 2023 Author Share Posted July 13, 2023 @jedimatt42 told me that the TI switch also had terminals on both sides but they were snipped off on one side and covered with a piece of plastic, IIRC. Quote Link to comment Share on other sites More sharing options...

From your picture, I'd say the black terminal are ground terminals, grounded to the encasement. If so you probably clip those, file down the nubs, and apply tape or liquid rubber to seal it. But I could be wrong too. I thought I had made a mistake once, but I was mistaken......;) Quote Link to comment Share on other sites More sharing options...

The metal rod part of the switch is on the black terminal side and on the original switch the rod is on the side used Quote Link to comment Share on other sites More sharing options...

+Atari2600PAL Posted July 14, 2023 Share Posted July 14, 2023 Just checked the switch with a continuity meter Each black / silver (on opposite side) pair are always continuous so I guess I can use either side It also shows each of the terminals nearest the label end gets continuity with the equivalent side terminal in the 2nd row when the switch is on and breaks continuity when off So I think I just need to look at the cabling to the existing switch to confirm which terminal should go where. Or even easier would be to just test the old switch when I take it out I guess Hopefully get time to fit it at the weekend sometime 2 Quote Link to comment Share on other sites More sharing options...
+jedimatt42 Posted July 14, 2023 Share Posted July 14, 2023 None of the switch terminals are to ground. This is opening (off) and closing (on) (when in the pushed in position) the 2 AC leads from the actual rear power plug. White has continuity to white only when closed, red has continuity to red only when closed. White connects from the power socket, through the switch, and into the transformer. If I recall correctly, red connects from the power socket, through the switch, through the external fuse socket, and then into the transformer. The switch never closes white and red to each other. Ground is connected from the power jack 3rd prong to the chassis. It never touches the switch. 2 Quote Link to comment Share on other sites More sharing options...

+Atari2600PAL Posted July 14, 2023 Share Posted July 14, 2023 I've found time this evening to strip down the PEB ready to sort this weekend The replacement switch seems to be a perfect a fit thankfully I'll have to solder (and sleeve) the leads onto the new switch though so am using the black terminals (the original also seems to of been using them, difficult to be 100% sure as the terminals disintegrated getting the leads off) Quote Link to comment Share on other sites More sharing options...
+Atari2600PAL Posted July 15, 2023 Share Posted July 15, 2023 Have fitted the switch and all seems to be ok so far (no bangs or smoke at least) A couple of pictures of the bracket without the switch in place (not great focus though) in case they are of use 2 Quote Link to comment Share on other sites More sharing options...
