A shaft 1 carries a sleeve 23 for rotation therewith but axially independent thereof and urged axially by a spring 24 such that two notches 28 (Fig. 1, not shown) on the end face 25 co-operate with a small wheel 29 to locate the shaft 1 with a snap action in a selected one of two stable angular positions. Two springsets 6 and 7 are respectively partly actuated by shoulders such as 27 and levers such as 31 in these two stable angular positions of shaft 1. A pin 13 moving in an arcuate slot 12 in support 11a normally limits the angular movement of shaft 1 such that only certain contacts of the appropriate springset are operated. If the shaft 1 is pressed axially (against the spring 24) the pin 13 moves into an appropriate slot 16 or 17 in member 15 (shown " exploded") which then allows an increment of angular movement of shaft 1 to cause the remaining contacts of the appropriate springset to be operated.
