A control device includes a control member ( 32 ) that is rotatable about an axis on a casing ( 22 ), with a gearwheel ( 100 ) mounted on the control member shaft to repeatedly flick a deflectable contact element ( 10 ) that is formed from a piece of sheet metal and that has vertical stems connected by elbows. The control member is manually depressable and has shaft ends ( 44, 46 ) that slide vertically in slots ( 48, 50 ) of the casing so either end of the control member can be depressed. An elastomeric member ( 34 ) lies in the casing and has upwardly projecting tubes ( 310, 314 ) that surround contacts, with the tops of the tubes being downwardly deflectable.
