Good way to anchor passive A/V selector switches to tabletop? - tabletop audio great for its intended purpose

Hello everyone,
I have a number of passive / V switcher I use to route the audio / video from my various DVR, DVD, VCR, etc., for television in the house.

The problem with these switch boxes is that they are from the back of the racks tend to be removed for attached cables. Although the application of pressure on the shelves, but Bob turns a lot, because they are much lighter than the cable. More information:

1. They are sealed units. I can not separate them from the land to drill into the shelves.

2. I have tried to strong double-sided tape, but returns after just one or two days.

3. Hot glue does not think very well on smooth surfaces of wooden floors.

4. Magnets aren'tag likelyThought UD (g).

So, has anyone advice on how the switch in conjunction with fixed shelves, entertainment?

I thank you all for taking the time to read them.

Have a good day!
