T Flip-Flop redstone mechanism
The T flip-flop system is a redstone mechanism that turns a toggled redstone sinal - as a button - into a stable one - as a lever. This mechanism works perfect in java edition, although in the bedrock edition, it does not work properly. For example, when i press a button with the T flip-flop sinal off, it is supposed to the sinal turn on, but sometimes that doesn't happen. GIF below
