Synchronous Switches
Java mod listed for Minecraft 1.18–1.21. Downloads from the MC Java Mods app on Android.
I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.








Synchronous Switches
This mod adds "Synchronous Switches" which can be linked together via a channel. When the state of a switch is toggled then any other switches that are on the same channel will update their output to match that state. In addition to the switches, there are channel input/output blocks and lights.
