    Has anybody got any potentiometer recommendations for Feed Rate / Spindle Speed overrides?

    It's not that I can't find any potentiometers that's the problem, it's the fact I can find too many, so I'm hoping somebody has a suggestion or two. I'm ideally looking for something a bit more industrial, that can take a knock or two.

    Look at the manufacturers of pushbuttons, and they'll often have matching pots, like these.

    Hi m_c

    Are you looking for a replacement for an existing control or are you building your own control panel ?

    if you go to RS Components for example
    http://uk.rs-online.com/web/c/passiv...potentiometers

    use the filters on the left hand side of the page

    select
    the maximum resistance
    the number of turns - one or multi turn
    type - linear
    mounting type - bush mount
    shaft diameter - 1/4" or 6mm
    element type - Cermet or wire wound

    etc
    by the time you have selected
    the options you require
    you will of reduce the 1500 potentiometrs down to half a dozen at most

    as an example if your looking for a single turn linear 5K potentiometer
    is this what your looking for ?

    for alternative UK suppliers
    try Rapidonline.com or uk.farnell.com

    Thanks for the suggestions. This is for a new panel.

    I was looking for something like what Ger linked to, but they're bit too expensive to get anything like that in the UK. A bit searching of RS has yielded 502-8637, which is listed as suitable for industrial controls. That's a 10K version, but I may go for a 5K.
    I still need to work out the finer details of wiring the panel, but at least I now have the basic components.
