Hi. This think
https://www.aircraftspruce.com/catalog/elpages/trimSwitches2.php
cost around 300eur, its make out of 2 switches (15eur each) and piece of poor plastic for ~270eur….
If there is any alternative for that? It’s crazy to pay such of money… Maybe someone make not certified colones ?
There is no such thing as a certified switch.
Looking at that close-up, it looks like someone did a 3D design in some 3D program and sent it off to a CNC subcontractor to machine up. Nowadays this is easy and is not expensive.
The microswitches will be off the shelf ones, purchased with a CofC so you can demonstrate due diligence that they aren’t chinese 
Presumably this trim switch fits somewhere i.e. is a dimensional copy of an existing one?
The TB20 trim switch mechanism is horrid and way overpriced, too.
The original Piper switch is way more expensive.
I’ve not seen anything like this in the non-certified world. We tend to have other ways of dealing with the trim runaway problem like an automatic cut-off if the trim runs for more than a few seconds.
There are no certification specifications for switches. You can install whatever you want in principle. A standard mil spec switch from Honeywell cost 1/10 to 1/5 of that. But of course, such a switch looks industrial/military rather than “sleek” and may of course not have optimal ergonomics.
