The present invention discloses a circuit board sensing module comprising a plurality of circuit boards and a sphere. The circuit boards form a hollow polyhedron with multiple surfaces and included angles. When the sphere is in any of the included angles, a circuit board is controlled to be electrically conducting, and the other circuit boards are open circuits in the meantime. Besides, the present invention further discloses a multi-surface operation apparatus comprising the circuit board sensing module. It comprises a plurality of control interfaces and at least a circuit board sensing module. When any of the control interfaces is operated, the circuit board sensing module enables the switch of the selected control interface, and shuts down the switches of the other switches. |
