Hate when you can't read thus you can't distinguish enabled button from disabled one? Have you ever caused reactor meltdown by forgetting to turn on cooling just because button state label was obscured by alt-icon? Do you wan't to shatter pitch black darkness by knowing what buttons are lit at middle of the night?
If answered (Y)es to any of these questions, you're in pure luck visiting this mod. This is re-texture for Switch Button by GalactusX31 updated for 1.0 .
New improved textures fit perfectly into Factorio art style and are designed in way that allows to read it's logic contents without being obscured by signal icon. Slight glow when button is pressed allows to see them while enabled in Pure Darkness (Pic.3 with ouk_ouk's "Rohlinheatagtmuf-Hdhaotaotfnllsape-atnsasri" mod).
