  • Publication number: 20040021151
    Abstract: Microswitch, comprising a base element (G) with a contact surface (KG) and an electrode (EG), and a switching element (S) with a contact surface (KS) and an electrode (ES) disposed opposite the electrode (EG) of the base element (G) at a distance (g). The switching element (S) is provided with a spring constant and is connected at least with a part of its edge portion with the base element (G) in a fixed manner. The contact surfaces (KG, KS) form a switching contact which is closable against a reaction force caused by the spring constant by means of a voltage applied to the electrodes (EG, ES). The base element (G) and the switching element (S) each comprise an auxiliary electrode (HG, HS) at a distance (a) from the electrode (EG, ES), to which a voltage can be applied. For opening the switching contact the electrodes (EG, ES) have a first voltage potential (U1) and the auxiliary electrodes have a second voltage potential (U2) of the voltage.
