I don't know if I got it wrong, but you want to set a default state where the switch is showing on.

If you want the switch to show on/off, you can actually use something similar to a real world kill switch,

You can use several approaches to achieve that, for example as Craig mentioned above, you can simply use textures, but in different slots.

You can also use a switch object with two meshes, the first mesh is just the case and the second one is the lever/button, this object has the two textures, on/off. Then you position the switch where you want it to be.

/edit

if you simply want the switch enabled would activating its bits set it to turned on? I'm unsure 🤔
