  Early Bonanza Throttle Mounted Gear Warning Switch Components


This tip comes to CSOBeech by way of Bo owner Jim H. Jim has identified the micro switch and lever arm that actuates the gear horn when you pull the throttle  and DO NOT have your gear down.


The switch is a V3-1 aka MS25253-1 and the lever arm is a JV-5, both available at Allied Electronics at CSOB prices!


V3-1 Switch, Landing Gear Warning - Found at Allied Electronics for ~$7.25

Jim confirms this is workable on the A to G model Bonanzas but ALWAYS check your parts manual to be sure of fitment.

Bonanza owner, Tom R., reports that it was a 20 minute job to replace his gear warning throttle position switch and the roller assembly is sold separately.
