    They call it a Microswitch , but it's a big switch that has a coil

    The coil is 28 volts DC to turn it on , energize it

    I don't understand why would a design or circuit want a switch to have a coil to ENABLE the switch

    Any reason why?

    Here is 3 things that I don't understand
    1.) Hold Voltage?
    2.) Drop out voltage?
    3.) Steady State limit?

    What does these terms mean?

    Why would you want a switch to have a hold voltage?
    Why would you want a switch to have a drop out voltage?
    Why would you want a switch to have a steady state limit?

    I think the switch brand name is called Microswitch

    It need 28 volts applied to the internal coil inside the switch to make the switch work

    SPDT plus a Coil

    If you don't energize the coil, the Switches doesn't work

    My question is why would anyone want a SPDT or DPDT switch that has a coil to be enabled or energized to work?

    You have to manual flip the switch but it has to be enabled / energized to make it work in both positions of the switch

    I think his switch turned into a relay so the switch question is done.
