Which component prevents lift operation if the seat is misaligned?

Explanation:
Electric contact acts as a safety interlock in the seat system. When the seat is correctly aligned, the contact is closed and the control circuit is completed, allowing the lift to operate. If the seat shifts out of alignment, the contact opens, breaking the electrical circuit and stopping the drive immediately. This real-time interlock is designed to prevent operation under unsafe alignment, which is exactly why it’s the component that stops the lift. The other options relate to mechanical aspects or procedures and don’t provide the automatic protection needed when alignment is off.
