Reintroducing Duplicant Interaction with Switches in Oxygen Not Included

This mod brings back a classic element of Oxygen Not Included gameplay, requiring your duplicants to physically interact with Power Switches and Signal Switches. If you miss the days when toggling a switch involved a bit more micro-management, then this mod is for you.

The Return of Manual Toggling

Prior to a significant patch in February 2020, switches in Oxygen Not Included did not change state instantaneously upon clicking. Instead, a click would generate a new task for a duplicant: to physically travel to the switch and toggle it. This mod meticulously restores that exact behavior, adding a layer of strategic planning to your colony’s power and logic systems.

Key Features of ManualSwitchToggle

This mod introduces several engaging gameplay mechanics:

• Duplicant-Assisted Toggling: Clicking a switch now creates a “Toggle” errand, requiring a duplicant to complete the action.
• Familiar Errand System: The “Toggle” errand utilizes the same visual cues and priority system as other essential duplicant tasks, such as opening or closing doors.
• Errand Cancellation: If you change your mind while a toggle errand is pending, a second click on the switch will cancel the assignment.
• Priority System Integration: Switches now fully support the game’s priority settings (1-9), allowing for fine-grained control over your duplicants’ tasks.
• Instant Build Mode Exception: In Instant Build Mode (Ctrl+F4), switches will behave as they do in the base game, toggling immediately without requiring duplicant intervention, mirroring door behavior in this mode.

Ensuring Compatibility and Stability

The ManualSwitchToggle mod has been tested and confirmed to work with priority 0 settings. While efforts have been made to ensure broad compatibility, it’s important to note that with any mod, there’s a possibility of conflicts with other modifications you may have installed. This mod has been verified to function correctly with all DLCs released up to the Aquatic Pack as of June 28, 2026.
