Replacement Power Switch TRS-80 Model 1:

If anybody needs a new on/off power switch for their TRS-80 Model 1 (or expansion interface) I have found a C&K switch from DigiKey that is a good replacement. The switch is a 4PDT switch that comes in Tin or Gold (Gold shown here). It does involve de-soldering the existing switch and soldering in the new one. DigiKey also has the Cap Tops for the switch.

For the expansion interface, there is a small metal bracket around the original switch that would have to be carefully removed and installed on the new switch. The "Flip/Color" Cap used on the expansion interface was also found and appears to be an exact replacement for the original.

Replacement Power Switch for the TRS-80 Model 1 could be purchased from DigiKey; (prices USD circa 2019)...

C&K Switch:
(401-1226-ND) F4EE 4PDT switch $4.20

C&K Switch:
(401-1227-ND) F4EE AU 4PDT switch $9.19

C&K RED CAP: (401-1218-ND) $.61

C&K BLACK CAP: (401-1215-ND) $.59

C&K ORANGE FLIP/COLOR CAP: (CKN10020-ND) $1.74

Thanks;
