I lived with it for quite a while, but when I started thinking about the case for the Pi2 and Banpi, I realized that I won't be able to do such a thing when it happens (I'm planning on using it with the Pi2) since the plug will be inside the case (and there's no way I'm going to remove/secure the lid every time it happens), so I needed some other way to do it. I quickly though of a normally-closed momentary switch that would be on a dongle that would cut the power when I depressed the switch, but I decided that the dongle would be a bit too much of a hassle to make. I then thought of mounting the switch on the receiver itself, but when I looked at it, it didn't seem like there'd be enough space for one.
The next day, I thought of a switch I pulled out of an old UPS, but when I tested it, depressing the button didn't do anything. I figured out that it was a fused switch, which acts like a breaker switch (in layman's terms), so that switch was out of the question. Later that evening, I remembered about the chassis intrusion switches I removed from the cluster nodes and found that it would work quite well despite how deep the button can be depressed (the depress depth to "activate" the switch is quite shallow). I used double-sided foam adhesive to mount the switch to the exterior of the receiver and left it alone for the night. The day after that, I performed the necessary modifications before testing it with Melty.
I have yet to use the button since the modification, but at least it'll be there and be a lot more convenient when it does happen - a quick tap is all it takes!
The receiver stands on the table like it's oriented here, so the switch is actually on the "side" and not the "bottom"; the wire enters close to the edge of the PCB due to its short length.
