| 摘要 |
This invention relates to a switch system comprising a housing and a sensor mass mounted in the housing, in which opposing sides of the sensor mass are clamped between an electrical contact mechanism and a spring mechanism provided in the housing, whereby a first side of said sensor mass rests on a first tilting element (5 or 5'), and the opposite side rests on at least three pivots (2, 3, 4 or 2', 3', 4'), whereby each of the pivots has a longitudinal axis and a first convex surface, whereby the pivots (2, 3, 4, 5; 2', 3', 4', 5') are provided to execute a rolling motion over the first convex surface upon impact, and to induce a three dimensional movement of the sensor mass (1) between the contact mechanism and the spring mechanism, against a clamping force exerted by the spring mechanism onto the sensor mass, whereby at least one of the pivots (2, 3, 4, 5; 2', 3', 4', 5') is tiltable between a position with electrical contact and a position without electrical contact. |
