can some one post a chart of how to wire micro switch with relay to pop door lock please ? just open, not two way. ::beers thank I'l be back
-
oh I wired the switch as horn chart but I would like to get get cut off power once it opens , right now I have to push the lever back for the power off

Eddie,
It sounds like all you need to do is attach a spring to the handle that activates the limit switch so it will return, canceling the limit switch and the power it sends.
Also, I'm not sure why you need a relay in the circuit. If you just use a switch at the door handle, with a spring return handle, that should do the job.
Maybe I'm missing something here.

Micro switches wont handle the amperage required by the door popper solenoid. You need a momentary microswitch to control the relay.

RT , once Jim told me put relay on any switching , the spring good idea.
Murcie, I'll double check with the store about it.
thank you

Eddie...
Even a momentary switch will make constant contact if you don't release it such as you described what you want it to do. A spring used to return the handle (switch tripper) after use will cancel the switch contact as long as you release the handle. That applies to a regular or momentary switch.
You have the right idea checking the capacity of the switch. No one here can tell you with any kind of accuracy what your switch capacity is unless and until you tell us the switch's specs. Check the power requirements of your popper and compare it to your switch specs.
The popper only requires a short power application to work, so wanting to release the power is the right idea. The popper should return after doing its job when the power is off.
There are other ways to assure the power is off after the job is done but that could be considered overkill. It is up to you.

Ron , those actuator(s) are from Cadillac
Since MM and Lambo Sam mentioned those from China sucks (like everything else) I'm using them to open doors but have secondary cable for incase of power fail. Anyway I'm going on weekend to double check about the micros. I was told back then they are ok for 12v . But I'll ask again
Thank you guys

LOL ok. Without you posting the specs of the switch, I can tell you with 99.9% certainty that if it is a true "microswitch", The rating of forward voltage (@12v) is well below 1 amp. Your door solenoid draws at least 3 amps unrestricted.
Most all (99.9%) "momentary" microswitches have their own return built in, unlike regular on/off switches that lock in their position.
Go ahead and use the momentary micro hooked to a relay that controls voltage to the solenoid. The switch will self disconnect once the handle is released.

Mike, OH BTW THANKS for the heads up about the OEM actuators. the price is right when shopping at junk yards. ::beers
