I should think so Paul but without a wiring diagram it may be a bit tricky? The clock is obsolete I know that. But is it a double or single pole switch device you want to by-pass? Single should be easy but double you’d have to pay close attention to where each lead goes that’s for sure. 😉
I am sure this model is a two pole timer, if my memory serves me right ( but please CHECK 1st ! )
it is live on 2 and 2a and nuetral on 1 and 1a, this then should bypass the auto timer, it should be easy to trace through but it is 1 and 1a that close to make a circuit and 2 and 2a.
