A B S T R A C T In a container filling apparatus for filling a tank compartment of a tank vehicle used for distributing hydrocarbon fuel it is known to provide a liquid supply control device comprising a tube adapted to depend into the compartment, a first switch adapted to be switched by engagement of the device with a co-operating part of the compart- ment, and a second switch adapted to be switched by liquid within the compartment rising to a predetermined level in the tube. In this invention, the first switch is so positioned on a body portion of a safety switch assembly that location of the body portion on the rim of a peripheral wall of the filler opening is operative to cause engagement and actuation of the first switch by the peripheral wall. The body portion may be provided with a channel part-circular in plan to receive a part of a circular rim and spring-biassed retaining logs may be provided in the channel. The first switch may be a micro-switch having a normally open pole and a normally- closed pole. The second switch may be a reed relay associated with a magnetic float, the reed relay having normally open contacts connected in parallel with the normally-closed pole.
