    I buy from Graingers and they seem to last forever, especially if you use a "simplex" control box - which is just a relay that takes the pump load off of the switch contacts - then any switch might go millions of cycles, or to the rated life of the relay.

    Thanks for the responce. The problem because of the location and the existing wiring the switch will need to carry ther pump load. Its a liberty pump 1/2 hp 115 volt.
    Thanks rt

    Mercury switches are more reliable and last forever, if you can find them.
