Switch

A Switch is a building that controls electrical circuits by enabling or disabling power flow to other buildings located downstream from it on the same circuit. A Switch does not affect any buildings that are placed upstream or before it in the circuit; its influence applies only to the equipment that is connected after the Switch along the circuit path. When flipped, the Switch controls every building that follows it on that circuit.

Because a Switch affects only downstream devices, the physical ordering of wiring and devices relative to the Switch determines which buildings it controls. Placing a Switch closer to the power source will allow it to control a larger set of downstream equipment; placing it near a subset of devices can be used to isolate and independently control that subset without impacting upstream infrastructure.

• A Switch does not influence any structure that precedes it on the circuit; those upstream devices remain unaffected by the Switch's state.
• A Switch controls all devices that follow it on the circuit path; turning the Switch on or off applies to every downstream building connected on that branch.
• Circuit layout determines control boundaries: to limit a Switch’s control to specific devices, route the wiring so those devices are positioned after the Switch while other devices remain upstream.
• Multiple Switches on the same circuit will each only affect the devices that are downstream of their own position; this allows segmentation of control by ordering and wiring rather than by proximity alone.

Use Switches when you need a simple on/off control that segments a circuit by position. Arrange wires deliberately so that devices you want controlled are placed after the Switch. Avoid relying on a Switch to isolate upstream equipment; separate branches or reordering are required if upstream devices must remain independent.
