    Default Damaged motor reversing drum switch

    Hi All,

    The motor reversing switch for the New Visby lathe I have has two issues:

    1. There is a LOT of play in the switching contactor mechanism meaning sometimes the detents won't engage relative to each of the 3 switching positions (forward, neutral and reverse), and;
    2. the bakelite insulator has been cracked from a blow to the side of the metal enclosure.

    I guess my question is: does a similar style switch still exist today as a direct replacement or do I need to somehow retrofit a modern drum switch into this enclosure?

    Any advice would be appreciated.

    Cheers,

    Flo

    G'day China.. My intention is to replace it, hence my question: can I buy something that will be a like for like replacement for what is installed (I'm assuming not, given the age of the machine) or do I have to get something current and make it fit?

    Cheers,

    Flo

    Hi Flo,

    I agree, replace it with a modern one ! Rotary switches are quite common though may be a little pricey. just make sure that it is AC rated for the load that you are using.

    You may have to buy a suitable box to house it as well.

    Reversing drum switches are available but it is highly unlikely they will be a direct physical replacement the attached pic is from Aliexpress.

    Hi Guys,

    By gum that seems very cheap ! You couldn't get one for that price here in the UK.

    Thanks for that.. I have seen these switches and I'm suspecting that what you're saying about direct replacements is going to be the case.

    Interestingly I have had a closer look at the existing switch and a lot of the excess play was attributable to a loose lever grub screw. The cracked bakelite piece was only a cover and so I used some JB Weld and repaired it and panel-beated the switch enclosure to relieve any residual pressure on the cover. So we'll see how it goes..
