Some sort of restraint or chain
 

I have this thing; it has a control panel on the top surface, so if it
rains the switches etc will get wet. I've made a hinged cover from
perspex. That's fine, except that when it's open it can fall back and
might get damaged. The perspex cover is 400 on the hinge side by 125mm.
Below the cover the control panel is only 35mm down. So there isn't much
room for any sort of sliding arm that would limit how far the lid can
open. I was wondering about some sort of miniature chain. Does anyone
have any experience of this problem, or know where I could buy a chain
with fittings, or can think of any other solution?

A search for "small cupboard stay" (perhaps mounted externally) or
"sprung hinge" (use them to bias the cover open and have a latch to hold
it down).
Alternatively, arrange for the cover to slide sideways, or pivot it in
one corner so that it swings out of the way and is held in place by a
latch of some sort.

Replace the switches with ones with an appropriate IP rating and
dispense with the cover.

How about a flat metal strut, one end fixed to the side of the control
panel by a screw/bolt so that it swings upwards, had a bent section at
the far end that holds the lid up.
Maybe the bent section can be forked so that it fits either side of
the plastic lid. Maybe the strut can be positioned so that when not in
use it just tucks alongside the panel.
All fairly easy to diy, otherwise buy a folding lid stay and adapt it.

I would use a helium balloon and a magnet. Ensuring the upper force was
lower than the latched magnet.

Is the lid when open near a wall to which you could fit a catch etc?

A picture might help as I at least can't fathom the options for what
might be attached where.

Would a sink plug chain do it? They can be cut to length and come with
fittings. You may need to buy two to get the fittings you want both ends.

I'm struggling to understand what a chain could be attached to stop
the lid dropping shut. Don't you need some form of strut? Possibly an
"over centre" one. Two bits, pivoted center and each end with a stop
that only lets the centre pivot go little past straight in one
direction.

Presumably the lid opens beyond 90deg.

Picture hanging chain as an alternative to bath/basin chain.

If there is something above and at the rear of the panel, fix a bit of
steel bar it lid or support, with a magnet to match it on the other
part. You can buy good strong rare earth magnets, or pinch one from a
very old, scrap 5.25 HDD. I use this method to retain my hut door wide
open against the breeze, when taking stuff in and out.

What's really needed is a miniature strut. As you'd find on your tailgate.

Well plastic chains used to be used as restraints on lids. Its a pity Sony
did not fit one on those little hinged doors on their VCRS.

Ah, possibly but then the lids is not acting as an operational
(partial) rain cover.

Can you get gas struts that don't want to be extended all the time or
weak enough to just counter balance the few grammes of a perspex lid?
