    Hi guys I am still working on my fan project and am considering other options before i commit.

    I am putting this in a separate thread as it is an attempt to solve another problem.

    I want to see if there are any "simple" uncomplicated solenoid switches.

    Example I want to open a latch to a door by actuating a switch.

    Is there a specific name for these.

    Thanks again.

    There are solenoids of all sizes and types. Old-fashioned "ding-dong" doorbells are one very common example of a solenoid. It has a ferrous center shaft that is moveable, and a coil wound on a bobbin that causes the ferrous shaft to move when energized.

    Then there are relays, which also come in all sizes, types and ratings. Relays are solenoids with one or more electrical contacts attached.

    I know that Mouser carries some very small surface-mount type relays, for low-voltage low-current applications. They look like minature bricks.

    Radio Shack also carries a variety of relays, but nothing as small as Mouser carries. They do have a fairly small DIP relay though.
