BE35 PLT INADVERTENTLY ACTUATED GEAR UP SWITCH DURING LNDG ROLLOUT AND LNDG GEAR COLLAPSED.

Narrative

THIS WAS A VFR PLEASURE FLT WITH PLT THE SOLE OCCUPANT OF THE ACFT. I DEPARTED VFR TO A FLT PRACTICE AREA. ONCE THERE; DID SOME AIR WORK INCLUDING 30- AND 45-DEG BANKED TURNS AND PWR-OFF STALLS. ON MY RETURN TO ARPT; I FOLLOWED THE ILS GS AND LOC. I MADE A FULL FLAP LNDG AND WHILE TAXIING ON THE RWY; JUST PRIOR TO THE TURNOFF FROM THE RWY; WHILE THINKING THAT I WAS REACHING FOR THE FLAP RETRACTION SWITCH; I INADVERTENTLY MOMENTARILY ACTIVATED THE LNDG GEAR SWITCH. I IMMEDIATELY SET THE SWITCH TO DOWN; BUT BY THEN THE LNDG GEAR HAD STARTED TO CYCLE AND THE NOSE GEAR AND L MAIN GEAR HAD RETRACTED/COLLAPSED; THE R MAIN GEAR REMAINED PARTIALLY EXTENDED. THE ACFT VEERED TO THE L AND STOPPED. I IMMEDIATELY TURNED OFF ALL PWR AND EXITED THE ACFT. IN RETROSPECT; I DISPLAYED POOR JUDGEMENT IN ATTEMPTING TO RAISE THE FLAPS JUST PRIOR TO EXITING THE RWY. IT IS UNFORTUNATE THAT THE DESIGN OF THE FLAP AND GEAR SWITCHES ON THE BE-35 MODEL G; WHILE SPATIALLY SEPARATED ARE ALMOST IDENTICAL IN FEEL AND OP. WHILE NOT THE PRIMARY REASON FOR THE INCIDENT; I BELIEVE THAT THIS SIMILARITY IS A SIGNIFICANT CONTRIBUTING FACTOR. ADDITIONAL TRAINING AND STRICT ADHERENCE TO LIMITING PLT ACTIVITY TO ACFT CTL AND COM WHILE ON ROLLOUT AND TAXIING SHOULD MINIMIZE THE POSSIBILITY OF A RECURRENCE.
