Cable to switch covering - use RTV or something else?

[Foster]

I have a project that part of it is a double pole double throw switch. The connections go into a covered cable (CAT5) and then to a molded on connector. Wires are soldered onto the switch. Once assembled there is no need to get to the connections again.

I'm looking for ideas on how to close up the back of the switch and protect the pins. In the prototypes I used Silicon RTV to cover the 1/4" high pins. I bend the cable down so it comes out the end of the switch. RTV between the switch and cable to hold it down, and then more RTV to cover the pins. Due to my amazing lack of eye / hand coordination the RTV has bumps and swirls in it.

I need to create ~50 of these switch / cable combinations. I'm looking for something easy and simple to do that looks reasonably nice.

Switches are 1 1/4" by 1/2" and are slide switches. They do not have mounting holes on them so a case or a box adds a new layer of problems.

I thought of trying to use small icecube trays as a form, but I'm not sure that the RTV will pop out of them.

Thanks for your ideas!
