Creating my own custom switch with specific function

[sathishkss]

Hi everyone,

What is the standard procedure for creating a custom switch in a custom model aircraft?

For example, there is a switch called "Gyro Horn" in Mi-17 Helicopter. It has a specific function. There are no simulation variables , no animation tags for the 'GYRO HORN' (at least from what I have seen so far) in P3D.

What is the procedure for:
1) Creating the switch?
2) Creating custom variables related to the function of "GYRO HORN"?
3) Mapping the function of GYRO HORN with the switch?
