Works as advertised. I installed in an RV4 my father built and it required a mounting plate but replaces the old switch and works well.

IGNITION SWITCH A-510-1

I purchased this because I own a seaplane and dont want to become stranded on a lake somewhere because i lost my keys... Besides, airplanes dont NEED keys.. the ignition switches are so cheaply made that they can be forced or picked by ANYTHING. So they really dont provide much security at all. I am opting to have a hidden start button that the thief would have a hard time finding AND... putting in a SECOND Master switch that will provide PRIMARY power to the aircraft.. thereby slaving the traditional Master switch. in other words, if you climb in and flip the master... nothing will happen... You have to flip the second master switch first. It will be hidden in plain sight in another location and not look like a master. The odds that a would be thief would take the time to figure all this out (which they probably could NOT because no other aircraft has anything like that...) is slim to none... In addition, I will NOT use the decal indicating off, L, R, and BOTH positions.. Therefore.. the would-be thief, wont even know for sure that this new switch IS the MAG switch.. so more for them to figure out... and for ME? I hop in... flip master one and two.. turn the MAG switch and push the start button... no keys to fiddle with (or lose) ever again. The unit is well made and works well, the knob is removable with two set screws so that it will not work loose from the torque required when using it.
