| 摘要 | In order to accommodate relative movement between the movable button 7 and the fixed part 1 of the switch, a plurality of leads 14 connecting a display 10 mounted in the button 7 to the fixed part 1 follow an S-shaped path 15 with first ends extending into the button 7 and second ends extending into the fixed part 1. The leads 14 may be in the form of conductive tracks on a flexible printed circuit board. Such a switch may be used in a typewriter or computer keyboard, for example, and may be controlled to display different legends corresponding to different selectable functions of the switch. | ||||||
