Abstract:
The invention relates to an actuator device for change of state of an electronic-control apparatus for underwater use and a system for underwater use comprising the combination of a said actuator device with an electronic-control apparatus for underwater use. The actuator device for change of state of an electronic-control apparatus for underwater use comprises a main body designed to be associated in a stable way with at least part of said apparatus. A peculiarity of the invention is that it comprises, associated with the main body, magnetic-field generator means that interface, in the operating position of the actuator device, with reed-technology sensor means of said apparatus for sending electrical information to means for management and control of the apparatus that are designed to change the state, in particular the state of supply of the apparatus, said management and control means being electrically associated with a supply circuit of the apparatus, which comprises at least one power-supply battery, for the possible opening or closing of the circuit.
Abstract:
