    摘要: The battery charging apparatus is made with small and low-cost components. It includes a first transistor (T1) with a control input through which the charging current flows into a battery (B) and a current source (T3, T4, R1, R2) for a control current flowing to the control input of the first transistor. The current source sets or adjusts the control current so that the first transistor is non-conducting or blocked and the charging current flowing into the battery is shut off when a predetermined maximum charging voltage is reached at the battery.

    摘要: An electric switch device for a machine tool has a switch-side contact element, that is held movably and is in contact, in a contact position, with a mating contact element so as to close a circuit. The switch-side contact element is a switching spring, which is acted upon by its internal stress to move into the out-of-contact position.

    摘要: A circuit arrangement (10) for detecting undervoltage in an energy source (12) includes a transistor switch (48) and at least one further switch element (30). The transistor switch (48) and the further switch element (30) are of low impedance in an operating state of the circuit arrangement (10). The transistor switch (48) blocks the further switch element (30) for interrupting the voltage supply if a supply voltage (U) of the energy source (12) is below a defined voltage value (Us).
