Help wiring two way light switch

Indeed they did install a round toggle switch was fitted in the box, with a locknut holding on a square faceplate.

This was still done in the mid 50s or thereabouts.

Early pvc cable came out circa early 1950s.

I never came across PVC cables used with a wooden box, in an as new installation.
 
Nothing wrong per se with 3/0.029, the major part of my lighting is still wired with it. View media item 26849
This property was built 1968 and when we purchased in 1994 still had what I expected to be the original Crabtree switches [as describe by Sparkwright]. I've worked in a number of my neighbours houses and found identical arrangements so have no hesitation saying it's original.

I have to say an installation with wooden back boxes and no earth wires would surely have to be older than 1968.

More like 1958 in my opinion.

Are you sure it was 1968?

Until moving in 1994 I'd never seen wooden backboxes but I'd installed many wooden patresses for china & bakelite switches and sockets.

I agree. I began work in 1963 for a major contractor which had an extensive stores. They still had some VRI cable remnants in stock, but most of what the had was PVC. They had not one single wooden back box, but lots of metal ones.
 
Thanks everyone The lack of a neutral was what stumped me, Will replace it with a plastic switch and get smart bulbs instead.
 
By 1963 I would have expected shallow metal switch boxes with nylon lugs as the norm.

I had thought there was a requirement for an earth on lighting installations by 1968, are you sure it wasn't built in 1958?
 
The Crabtree switches with the C logo on the toggle, wooden switch boxes, red white and blue, no earth on lighting circuit - all before 1968 surely?

Red white and blue early pvc - that's a 1950s-early 1960s thing.
Just looked at the deeds :oops: 1965 so just before the 1966 edition.
Other that that a neighbour were the 2nd to move in, the year after they married.
I recall seeing these properties being built, she started back to work in 1966 when I started high school, so they must have been the other end of the road.
The guy living in the adjacent road has shown me pictures he took of the 2 houses being demolished to make way for the road, he is the same age as me [65]
