Abstract

Ein Schalter (10) mit einer längs einer Bahn (32) zwischen einer Ruheposition und zumindest einer Schaltposition beweglichen Masse (17) weist zumindest ein erstes Rückstellelement (18) auf, das die Masse (17) in ihre Ruheposition vorspannt, sowie einen über die Masse (18) betätigten Schaltkontakt (27). Das erste Rückstellelement (18) umfaßt ein Betätigungsteil (15), das den Schaltkontakt (27) betätigt, wenn sich die Masse (17) gegen die Kraft des ersten Rückstellelements (18) aus ihrer Ruheposition in Richtung ihrer zumindest einen Schaltposition bewegt.

Figure 00000001
A switch (10) with a mass (17) movable along a path (32) between a rest position and at least one switching position has at least one first restoring element (18) which prestresses the mass (17) into its rest position, and one via the Ground (18) operated switch contact (27). The first reset element (18) comprises an actuating part (15) which actuates the switch contact (27) when the mass (17) moves against the force of the first reset element (18) from its rest position towards its at least one switch position.
