Its called a micro-switch and they are fairly generic--look for a parts set similar to yours. If you need the actual plastic button array try Toshiba who might still have it.

If it is skewed and or will not adjust you have a convergence circuit problem. If this is the case let me know and I will tell you what is involved to repair the set.

Toshiba TV 50HX81


Check fuses on Power Supply board (F850, F851, F852) and all other fuses. Replace blown fuses (will need an ohm meter to check fuses). I would also replace the two convergence amps (STK392-110's on the signal board, the big black ICs on the two heat sinks). This worked for me.
