Switching device and its use in a selector switch or a program control apparatus |
摘要 |
The movable contact (52) of an on-off switch is moved, through drive means (5), by balls (4) rotated by a disc (23) in the peripheral surface of which regularly spaced cavities are provided to accomodate the balls. The balls can be either withdrawn or inserted through a channel or bore (20) which can be closed by a plug (7) so that the switching pattern can be varied depending upon the angular position of the disc. The device can be used e.g. in a selector switch or a program control apparatus.
