Greetings All;
Let me preface this by saying I have searched for answers on the threads previously posted before giving you a ? that may have already been answered or posted elsewhere, so I appologize in advance if this question is redundant.
I have a small homeowner-sized plow that uses a 12v linear actuator to raise/lower. The actuator has to be replaced, (i found out that these actuators are not meant to use their on-board slip clutches as a means to stop full extend/retract cycles- they are meant to be wired with limit switches to accomplish this...mine no longer stays up with a load,but lowers by itself after pwr. is cut)
I need to build a limit switch box for the plow frame, and wire it to my DPDT switch in the cab. The actuator draws too much current to use snap-action micro switches wired directly to motor voltage. I need a schematic (in laymen's terms) that uses 2 micro switches with 2 diodes to allow current reversal after one switch is tripped, which in turn runs through 2 30 amp 12v relays to run the actuator motor. I have come close to the answers, but not found exactly what I need.
Thanks in advance for any help you might be able to provide.
