TRS-80 Model I NEW POWER SWITCH.
If your Model 1 power switch it sticky, or doesn't stay pushed in, or bypassed because it failed... you need one of these.
They take a bit of work to replace, but the result is a crisp easy-to-press button just like when the computer was unpacked when new.
It's a new part and will work well for decades.
