A quick look inside one of the electrical boxes associated with some styles of street lighting, and the repair of the Sangamo time switch inside.
Also featuring the sudden disassembly of the more-complex-than-expected solar dial that compensates for differing hours of darkness throughout the year. (I did actually manage to reassemble it again after two goes.)
I'm not completely sure what component was missing from the box. I don't think it was a contactor, and the only convenient ballast to fit remotely in local street lighting is the older mercury vapour type with no high voltage ignition pulses.

Peace N love..
Took me 5 years, but I finally got one, and by one I mean two!! One is from 1988, has died due to green death from the NiCd leaking taking out multiple traces (can be re-wired with jumper wire, but still, PITA), and is also a 52 degree dial so more for suvveners, other's a "modern" one, 4-pin type, made in Sept. 2012 so almost 10 years old, 80mAh NiMH battery dead and starting to go fluffy but no damage, but the date wheel part was stuck somehow, found out when I tried advancing the wheel to August and crunch went multiple teeth on the big white gear, so, I undid the nut and stole the part off the other clock, stuck in a new 150mAh battery and it's working fine!!! Now to find a use for it!!! 😛
Excellent devices and description. Pity, it's difficult to find anyone to service them and Sangamo recommend throwing them away and getting new ones.
I used a Sangamo time switch as my alarm clock in the 1970s (19yo) !
Hooked up to a vacuum cleaner next to my bed – friends loved it !
Is that just a normal 1.2V rechargeable nimh cell? Peer as I might I can't quite make out the markings. I ask because the lighting in my flat stair has stopped coming on at night, and it seems we've got exactly the same model of timer as this. I expect the same failure has occurred, and it would be nice to have a replacement battery to hand before I pull it out of the wall.
I used to have a Big Ben alarm clock that was proudly marked ‘ Made in Scotland’
Ha Ha this made me smile I used to work in the Sangamo Felixstowe factory many years ago 😁
Sangamo? Sangamo… I used to maintain a sonar system made by sangamo (SQS-23) I wonder if it’s the same company. How many companies of that name could there be?
it says “do not loosen nut” … “ooh this is really complex”.
I fantasize that such a warning conceals a big spring which sprays complex parts and spills your whiskey,
I found the chip datasheet for a bare die version. It seem to be a standard low cost chip for any clock but encapsulated for this type of application
I need to find one of those for my odd clock collection, I’ll have to start looking around.
Oooooh! It's "Quartz!" What are we in 1977?
if it's Bn, Bk, Bk, G, Bn R it's 10M (thank you google)
Remember Venner?
It's like a wadokei… old timey Japanese clock that divides twelve "hours" per day evenly into six daylight and six nighttime "hours."
