Abstract: The present invention relates to a plug-in power supply for supplying a consumer with a low voltage, and in particular to a plug-in power supply wherein the mains plug unit is exchangeable in the form of a conversion plug system. The plug-in power supply comprises a housing having arranged therein a voltage transformer module for converting a mains voltage into the required low voltage, and an exchangeable mains plug unit with at least two mains plug pins.

Abstract: The mobile or portable telephone includes a circuit board (15); a battery compartment (5) for a battery (20) located on a first side of the circuit board (15) and a pivotable card receptacle (10) for a telephone card arranged on the first side of the circuit board (15) next to the battery compartment. The card receptacle (10) is pivotable between a first position (25) in which the telephone card cannot be inserted or removed from the card receptacle when the battery (20) is in the battery compartment (5) and a second position (30) in which the telephone card is insertable or removable from the card receptacle even when the battery (20) is in the battery compartment (5). A button (B) may be provided for activation of the pivoting of the card receptacle into the second position from the first position. The card receptacle (10) preferably locks in the first position (25) when put in the first position and may be unlocked from the first position (25) by operation of the button (B).
