Loose switch hardware

[ThunderChicken]

I noticed the other day one of my switches n my ST-16 felt soft or mushy. I know from experience that one particular switch always had a firm positive tactile click. After the flight ended I inspected all of the decorative collars and found others that were loose. If a switch is mounted and soldered to a circuit board the solder joints will eventually break and you could lose function of that switch.
Check your hardware but do not over tighten those collars.
