Duck-Duck for "Loc-line' tubing... It is a modular system that consists of a bunch of snap together bits that form a tube that is easily bent to the desired shape but that will then stay where put unless enough force is applied to bend it again.... There are also nozzles and mounting fittings, valves, etc. to make a complete system.
It comes in various sizes - US 1/4", 1/2" and 3/4" bores - or metric equivalents.....
The bending resistance is a function of the size and the length of the assembly.... the 3/4" is stiff enough to (barely) hold up a joystick pod, the smaller sizes less so. From the description of the application, I'd be looking at 1/4" as its a fairly short length (I think) and light load...
It's most common use is for cooling jets on mills and other machines. But it is also often used on medical gear for this sort of positioning task, at least one of the US vendors has a catalog of medical / accessibility fittings and assemblies, mostly in the 3/4" size...
The challenge may be to find a switch that works with a 1/4" line and still has a big enough button....
Also note that the bits are relatively hard to snap together or pull apart, I highly recommend getting the special 'plier' tool they make for the task....
