Several people have asked me about these time switches and as I
have one complete with instructions I have decided to reproduce it
here.
For instruction leaflet click on links below:
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 time switches 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.
