electric control panel latch/clamp?

(1/2) > >>

happyfunball:
so I've decided to use swappable control panels in the cabinet I'm working on. I want to be able to swap them with a minimum of fuss. And I was thinking they probably need to be locked down in some way so they don't slip of pop off for any reason. I was thinking I could use like spring loaded cabinet clamps for that.

however, I didn't want to use anything where I have to stick my hand in the coin door and fish around trying to pop it off or open a latch. So, I figured it might be possible to use some sort of electronic latch where you could just push a button and the latch/lock would just release and you lift it off, unplug it, and swap, press the button, and the new one is locked down.

has anyone done this? some searches on the forum haven't really popped up much relevant but maybe I'm using the wrong terms.

or am I overthinking this and there is some really simple solutions I've missed?

I can't recall having seen that done but it sounds like it should be pretty doable.  I say go for it  :cheers:

I've got a similar requirement. Was thinking along the lines of some sort of bolt or pin retracted by a solenoid, but thats as far as I got....

PL1 helped me design something similar for the Mark 2 or 3 of my NRFT design.

Check out these small linear actuators:  http://store.firgelli.com/Firgelli_PQ12_S_p/pq12-s.htm

You want a LA over a solenoid so it's positional and doesn't have to remain under power.  You'd just need a three position switch.  Pos 1 (+) for locked.  Pos 2 (open), Pos 3 (-) to unlock.  You could run two or a dozen off a single switch providing you want them all to fire together.  I figure two would do you.  They're a bit pricey but all you'd need to do is just line up brackets with through holes.

You could try something like this

you would just need to fashion a catch of some sort on your panel.  It's a little cheaper than a linear actuator and all you would need is a button to hit it with 12 v to open.
