Further to all the talk of relay decks, there is another way to allow more than 1 trim switch, available from the proprietor of this forum, Matt Dralle, in the form of The Governor - here's a link to it:
http://www.matronics.com/governor/
Its primary function is to allow for the trim servo speed to be adjusted - I understand some folk have found the natural speed of the servo too high for their liking - but as bonus you can add as many extra trim switches as you want. (eg one on the panel and one on each stick-top.) I have fitted one to my trim circuit and in my tests so far (not yet flying) I find it is entirely satisfactory. In the picture of my panel (I posted a link to it yesterday) the small hole at bottom left adjacent to the trim switch is for screwdriver adjustment of the trim speed.

I recently investigated using a Vertical Power system as the relay and speed controller for my elevator trim servo with stick top switches, with some advice from Tony Kay. In brief, Tony spoke to Andy Draper who confirmed that, due to the critical nature of the trim on an all-moving tailplane such as the Europa, the LAA wouldn't sanction any electronic controller/device in the trim circuit between the trim switch and the servo, in case of failure. I believe the RAC relay deck is ok because it switches the power but doesn't try to electronically control it.
On that basis, would this unit be permitted - I'm not sure where it goes in the circuit?

Hi Rowland,
Is what I understand that with the Matronics, you can use the original switch, plus stick trims? I think to be able to vary it inflight, or to have a cruise trim and a circuit trim would be nice. One way would be to use the controller, or bypass it, but if you bypassed it, you would need the relay again? I need to check if there is only one suitable relay. Seems to me I will need a relay if I want to persist with a two speed trim setup. I need more input from current flyers please. Anyone?

I have the the matronics governor and personally I found it too quick in flight, it was easy to overshoot then undershoot, so I turned down the governor a notch or two and found it works well,
in the circuit isn't a problem with the Ray Allen stick grips as you are trimming away as you are doing other important tasks at the same time, and who said men couldn't multi task
