Different aircraft have different setups Patrick.
A stock UH-1 Huey would have five switches on the cyclic grip.
A two stage intercom/radio transmit switch that looks like a trigger on the front side of the grip generally operated by your index finger. A push button switch on the top left edge of the grip for the Force Trim release and operated by your thumb. A push button switch on the left side midway on the grip which had no function, also operated by your thumb. A push button switch at the lower left side front of the grip which operated the external cargo hook release, operated by you Little finger. The last switch was the "coolie hat" which operated the rescue hoist as a backup to the crewman's hoist control in the cabin.
The Huey collective lever had six switches. Engine start trigger under the throttle, engine idle detent switch on top of the collective. Two landing light switches, searchlight switch, a coolie hat for steering the search light, and a Nr RPM control switch. The landing light switch turned the light on and a second switch moved it from pointing straight down to slightly above horizontal, the searchlight switch turned the searchlight on/off and retracted it.
Modern helicopters have an altogether different array of switches.
