Heavy Duty Switches by smittylv is mainly worth checking through block placement, pickup, upgrade, and repair, traps, power, doors, and devices, and base persistence and multiplayer permissions. Do that in a copied save or test server before changing a main world.
Use Nexus Mods listing to confirm exact file names, branches, screenshots, and update notes; then judge the MOD by the in-game parts above, not only by whether the game launches.
- Place the blocks in a copied base, upgrade them, damage them, repair them, and restart.
- Run the powered or interactive part through a blood-moon-style stress test if relevant.
- Have another player interact with the block before adding it to a shared base.
