Hi,
I'm thinking on using a small solenoid to control a box opening.
I've seen an example in this video.
The soloneid of the video is a pull-push one:
I guess that one end is the pull actuator and the other end the push actuator.
I've found on ebay a few cheap 5v solenoids, which I think is great because I wont need a relay, just a transistor to control it but I'm not very sure on what to get. I think what I need is a pull solenoid (like this one, I imagine) but for the same price there is this pull-push one which I could use for other experiments.
From the photo I don't get how this is pull-push as only seems to have one end?
Does anybody know how this works?
Thanks!
