I have 2 broken ones. They don’t sell the lever by itself do they?
Actually you can put the lever right back on, the end that looks like a little T can be poped back in with some careful effort, If your lever is broken somewhere in the middle then you might just have to tape or sauder something on yo it,
No, there is no replacement. What you might also be able to do is completely replace the switch inside (one with the lever). These contact switches are fairly cheap, and you might be able to find one that fits.
