Title: Left switch/ made in Japan
Post by: Garry32 on August 26, 2015, 03:33:02 am
Hi does anyone know when the underside of the left switch changed from engraved made in Japan to embossed and then  removed altogether.
Thank you Garry :)

Are you saying the earliest ones were engraved (like stamped)?  I thought the earliest ones were embossed (raised) letters.

Hi Mark yes I have two, one was a reconditioned one from Yamiha when I bought was advised it was off a very early low numbered sandcast and the writing is engraved.

i have never seen what i believe to be a factory oem switch to have raised font.

without going into detail why i believe 232 and 2157 switches are original 1969 parts, i'll just say i believe they are the switches that came with both bikes from the factory in 1969.  both LH switches have raised font.  i will check 1865 and report back if this thread keeps going.

a Japanese friend of mine very recently bought me a "no turn" LH switch from Yamiya.  it has stamped (recessed) "Made in Japan" font.  it must be a repro switch because Yamiya advertised it as a repro switch.  this switch has a TEC horn button and "HM" lettering fitted.  except for the recessed font, it looks like an original switch.  the only other difference i note, the insulation of the wires looks slightly different, shinier and may a half gauge off in diameter from orignal

1676 do have "made i japan" under neath and the other lettering too.
The "Tec" from horn button is that what is to be deciphered from the starter button too?
And I've had this thing for more than 46 years and never thought of looking for letters!

I also have an unrestored 40:: sandcast and the left switch underneath wording made in Japan is recessed also.
Thank you Garry

Steve, are you talking about a replacement switch?

I have double checked and 97 and 576 have raised letters.  So if I'm understanding all this the earliest version had raised letters and it switched to recessed letters somewhere between 2157 and 4000+.

Thanks Steve,When I bought the switch  from Japan they advertised as genuine and it was over £350 buy the time it reached me it was about £450
Couldn't it still be genuine, just not earliest?

The logic would be embossed before the stamped... But...
Ujeni could he tell us how is the marking on the #410 embossed or stamped?
Ujeni if you read us, we need you!!

all i am saying is the switch i bought was advertised as repro.  Yamiya are good people.  if that's waht they say they sold you, then that's what they sold you.

Fascinating to know if recessed font are orig.  Sounds like must be.  I've only seen raised font.

#302 (99% certain to be original) - recessed
#8054 (99% certain to be original) - NO lettering

NOS replacement fitted to #5298 in 1993 has embossed lettering.

interesting.  i'm 99% certain the handle bar switchgear to 232 is from factory.  both were weathers the same, both anodized housings were faded the same.  kill knob pointerless.  lower horn housing has raised font.  sounds like weither could be correct since there's no way to prove which was used when.

But maybe there is no sooner or later one or the other? Maybe it's just two manufacturers
different that used two methods of markings at the same time... One highlight and one indented?
This could explain the confusion that reigns today... Just an idea...

Would be interesting to survey the owners of all pointerless 0n/Off switches from earliest VIN to see what percentages of each show up for unmolested machines. Doing the same for LH switches, then we might understand more information on this topic.
I always assumed the early poinerless kill switches would have been manufactured at the same supplier, since there were probably less than 800 produced.

Of the sandcast and K0's I have only five have the stampings all others are embossed. My earliest two sandcasts are stamped (three digits) and one mid range 4xxx is stamped and two k0's stamped one 8xxx and one 101xxxx. Marty K.
