Optical switch to control the energization of an electric charge

An optical switch comprises a light emitting device (E) and a light receiving device (R) loaded by one of at least two elements (E1, E2) of an equipment (E), which are associated with a control module(MC) for energizing or de-energizing an electric charge (CE) in function of the relative positioning between the elements (E1, E2) displaceable relative to each other; and a light reflecting means (RL), which is loaded by one of the elements (E1, E2) and reflecting to the light receiving device (DR) a light beam (FL) received from the light emitting device (DE), thereby energizing or de-energizing the electric charge (CE), when the elements (E1, E2) are in a first relative positioning, the light receiving device (RL) no longer receiving the light beam (FL), and changing the energizing state of the electric charge (EC), when at least one of the elements (E1, E2) is relatively displaced relative to the other, changing a second relative positioning between the two. 光学开关包括光的发光装置(E)和光接收装置(R)，这些装置由设备(E)的至少两个元件(E1、E2)中的
