Amiga 1000 keyboard switch
« on: Fri, 31 March 2017, 09:46:24 »
Hi
I'm looking for replacement switches for an amiga 1000 keyboard.
I have attached an image of the switch.

Does anyone know where to get a replacement. 

Thanks

tbh your best bet would be to buy another amiga 1000 and harvest the switches from it

Are there any other keyboards that used the same switches. Those a1000 keyboards are rare to find.

I know of two keyboard switches that were used for keyboards for the Amiga 1000.

Yours seem to have this one: https://deskthority.net/wiki/Mitsumi_standard_mechanical
The other type of switch has a metal top, (https://deskthority.net/wiki/Mitsumi_miniature_mechanical), which I think is more common but not pin-compatible.

Can a alternative be used?

What part of the switch is broken? If it is not the slider, then maybe you could mix and match parts with one that has an Alps-compatible slider. Apple Extended Keyboard II (AEKII) - in a variant that was made in Japan - has that type of switch. AEKII's with other switches are more common.

I think all Amigas - from the Amiga 1000 up to the 4000T and CD32 - used the same serial protocol, only different connectors. So you should at least be able to connect a different Amiga keyboard to it with an adapter.
(The only exceptions were the 1200 and 600 that had a ribbon cable to the motherboard, but still had serial communication between components on the motherboard, if I'm not mistaken.)

It's the white plastic that the key sits in. When pushed down it doesn't return.

But can you see that that is what is broken?
If the slider does not rebound after pressed then it is probably something broken inside it.
