    Default Temperature switch for temp light rather than a gauge.

    I have continued struggles finding a replacement temp switch for a 1963 221 ford interceptor. Repeated attempt result in a sending unit for a temp gauge and not a temp light...ie. a good old fashioned idiot light.

    I have waded through this problem with multiple parts stores and inevitably end up buying the wrong part.

    Any ideas or advise on a good source for the old and original temp switch?

    A temperature gauge is invaluable, and will allow you to see when/if temperature begins to climb.
    An idiot light only tells you when temp has reached a dangerous level.
    Why not accompany a good gauge with an idiot light?

    Thread size in not a problem...standard stuff.

    My experience is no one can supply an actual switch. I have purchased 4 different units now. All screw in fine, but send a continuous current that gets stronger with temp rise. Correct unit will only send current when too hot.

    Any recommendations on a source for an actual switch?

    I understand your point. Better information with a gauge.

    Was thinking to keep original.

    Thoughts on upgrading to a gauge and how that affects originality of the boat. 63 Thompson/ChrisCraft Sea Skiff

    I'd bet the four you were sold are sending units for gauges....they have a thermistor inside so the current they will pass veries with temp.

    switches aren't that hard to find....try search 200 deg fan switch....last one I saw on am 0 zon was under $10 and had a few adapters with it.
