ABSTRACT:
A control device for valves and the like, including at least one control switch (13) which is inserted in at least one optical conductor (18,118), and is connected to the valve actuating means in such a manner that it will be automatically actuated (i.e. opened or closed) upon the actuation (i.e. opening or closing) of the valve, thus interrupting the respective conductor (18,118) or re-establishing its continuity. The conductor (18,118) is comprised in a warning and/or control circuit, and the opening or the closing of said switch (13) generates a signal which may be utilized, for example, to detect and/or to record the actuation of the valve and/or to activate a television inspection system. The control switch (13) is formed by a connector for optical fibre and comprises two complementary and co-axial connector members (14,15) one of which (14) is stationary and the other of which (15) is movable axially and is urged towards one of its end positions (i.e. opening or closing position) by a spring (17) and is held in the other end position thereof (i.e. closing or opening position) by an associated movable portion (2) of the valve actuating means, in the position assumed by said portion at the end of its stroke for closing or opening the valve.
