| 63 | Snap-action switch for alternating current | EP83108928.9 | 1983-09-09 | EP0103284A2 | 1984-03-21 | Rossi, Guglielmo |
A snap-action switch, especially microswitch for alternating current comprises at least one stationary contact (2) on a stationary contact part (1) and at least one movable contact (4) on a movable contact part (3). In order to open the switch in the proximity of the zero crossing of the switch current, on the one contact part (1; 3) there is an electromagnet unit (8) excited by the switch current while on the other contact part (3: 1) is disposed an armature unit (12) made of ferromagnetic material which is located opposite the electromagnet unit (8) |
