| 摘要 |
The invention refers to a punch switch with automatic adjustment, carrying a housing (3) to receive at least an operable contact (7, 19), with an actuating means (5, 27) which is displaceably conducted in housing, and which works to actuate at least a contact (7, 19), which is maintained by an elastic element (11) in a resting position extracted from housing, and which comprises a skid (5) conducted in housing, and a punch (27) which is displaceably attached therewith in actuating direction, while punch (27) comprises first blocking elements (45) which can go out an angular position (adjusting position) which makes possible adjustment between punch (27) and skid (5) by punch (27) rotary movement around its longitudinal axis by a predetermined angular magnitude, so that skid contacts second blocking elements (29a) (blocking position), thereby achieving a position blocking between punch (27) and skid (5).
