ABSTRACT:
A small electrically operated valve in which a control solenoid sub-assembly is mechanically associated in a non-dismantleable fashion by means of a face with the corresponding face of a pneumatic switching sub-assembly having a valve member. Each of the two sub-assemblies is of plastics material and comprises passage portions which may be brought into aligned relationship to form at least one aligned passage capable of receiving at least one small cylindrical metal pin, a first end thereof being positioned below the surface at which the entry of the aligned passage opens, while the other end is in the vicinity of a metal protective portion which is positioned inaccessibly in either one of the two sub-assemblies and which is disposed substantially transversely to the axis of said aligned passage.
