A stylus input device includes a grip, a surface-contacting member, a pivot joint, and first and second sensor modules. The pivot joint is disposed to connect the grip to the surface-contacting member and permit tilting of the grip relative to a working surface when the surface-contacting member is in intimate contact with the working surface, and is configured to permit and guide axial displacement of the grip relative to the surface-contacting member. The first and second sensor modules are disposed respectively in the surface-contacting member and the grip for sensing two-dimensional movement of the surface-contacting member on the working surface and axial displacement of the grip so as to respectively generate a two-dimensional movement signal and an axial displacement signal that are to be converted into a positioning signal by a processing unit for subsequent transceiving by a transmitting module.

A remote controlled interactive power switch includes a first coil for controlling a switch contact to be closed by suction, a self-locked device for locking the switch contact to keep conducting state by mechanical self-locking, a second coil for controlling the self-locked device to be disengaged and a power supply control circuit. The power supply control circuit is connected with an interactive control module which includes a remote controlled interactive connecting unit, an interactive monitoring unit, a switch-on signal producing unit and a turn-off signal producing unit. The present invention can simplify the complex control circuit and thoroughly resolve the technical requirements of the power switch with high make-break capacity. Additionally, the present invention produces consumption only when starting the on-off switch, and after starting and under normal operation, the pulse magnetic energy coil keeps an inactivity state, no consumption, no heat and no noise.
