    Hello everyone,
    I'm new, and joined because I need help with controlling a linear actuator. The actuator is actually going to be used on my truck to control the position of the vanes on a variable geometry turbo. This exact setup has been used, but it only is wired to a momentary switch, so it isn't precise and is difficult to get in the same position everytime.
    The actuator isn't directly controlling to turbo, but is just acting as a stop, or travel limiter. I esentially want to be able to wire up a 3 position switch and have each position correspond to a set point in the actuators range of motion.
    Example:
    2" stroke linear actuator
    Switch down (or position 1) = 2"
    Switch middle (or position 2) = 1.5"
    Switch up (or position 3) = 1"
    I'm not stuck on those values obviously or the exact switch setup, but would ideally like 3 set positions I can switch to. I am currently using this actuator on a momentary switch:
