Sangamo Weston S258 S259 S260 S261 etc.

 

Several people have asked me about these time switches and as I have one complete with instructions I have decided to reproduce it here.

The mechanism has prongs which slide into sockets in the bakelite housing. You can pull it out to gain access to the terminals and fixing screws.

The unit that I have has a spring reserve and a day omitting facility. It is one of a range of timeswitches with switch contacts rated at 20 Amps extensively used in the 1970's. It has been in use for 20 years in my last home to control a 3 kW immersion heater.
The head office and works of Sangamo Weston Limited were in Enfield, Middlesex, England.
