An insulating disc 14 carries printed circuit contacts (Fig. 2, not shown) arranged in the circuit of a vibrating armature drive magnet to ensure 180‹ rotation of the disc each time operation is initiated. An eccentric disc 17 on the rear of the disc 14 drives a lever 11 pivoted at 12 and having a slotted extension 10. A bent over wire spring 8 is a friction fit in the slot in the extension 10 and is coupled at 7 to the pivotally mounted counterweighted crossing barrier 2. When the barrier is being lowered additional contacts op the disc serve to energise a bell or alarm (Fis 4, not shown).
