Trim Servos: Operating Coolie hat SW and Panel Rockers

[Janekom]

Hi, I found that one cannot connect the coolie hat switch as well as the panel mounted rocker switches simultaneously due the the fact that the rockers ground the servos to make them stop quicker. I have searched this forum for a solution but found none.

I have then drawn out my own version of a "Relay Deck" that will take both the coolie hat SW and the rockers as inputs and have two outputs to the elevator servo as well as the aileron servo.

Now before I go and design the circuit board ( in other words re-invent the wheel ), is there a unit like this available commercially. Keep in mind that I am in South Africa.

Thanks.

Matronics offers a small unit that does this and also allows you to fine tune the speed of the servo. Works great!

Thanks Vern,
I see that I will need two units.

Check out the relays from Aircraft Extras. I just got mine, and they're great!
