'90 Accord's ignition switch failed after just 68,800 km use
 

This switch ( part # 35130-SM4-305 ) on a '90 accord ( Japan made )
suddenly could not feed a current to engine ( F20A )'s distributor after
cranking, so this accord was stuck in a slow moving traffic, causing
obstruction to traffic.
If your car uses this switch ( fitted below key slot, K69-1 embossed on
its black plastic casing's bottom), & switch is not new, better let this car
carry a 3 amp wire ( insulated, e.g. 18" long for a SM4 & F20A ) with a
clip* @ 1 end to grip your battery's +ve terminal, & the other end ( bare
) to slip into your distributor's +ve input terminal ( a wire with a black
rubber insulation, on a F20A ) to ( if necessary ) feed a 12v current to
distributor, so your engine can be started & run like normal until you can
replace this un-durable switch. This clip* will enable easy dis / re
connection to turn off / on engine.
I never knew any ignition switch can fail @ just 68,800km : the interior
of this failed switch has no crack / dirt inside !
