Apparatus for switching sim cards disposed in communication equipment

An apparatus for switching from a first Subscriber Identity Module (SIM) card with a set of first contact points to a second SIM card with a set of second contact points, the first SIM card and the second SIM card both being disposed inside a communication equipment comprising a battery with a set of third contact points and a casing with an inner wall. On the inner wall, a set of resilient pins for contacting the third set of contact points on the battery and a set of four contact points for contacting the first set of contact points of the first SIM card or the second set of contact points of the second SIM card, said apparatus comprising:

• a disc, rotatably mounted on the inner wall, having a circumference partially exposed outside the casing of the communication equipment;
• a first slot, formed on the disc, for containing the first SIM card inserted securely into the first slot where the first set of contact points on the first SIM card are disposed toward the inner wall;
• a second slot, formed on the disc, for containing the second SIM card inserted securely into the second slot where the second set of contact points on the second SIM card are disposed toward the inner wall;
• a first set of openings, formed through the disc, corresponding to the first slot;
• and
• a second set of openings, formed through the disc, corresponding to the second slot;
• wherein if a user operates the communication equipment by use of the first SIM card, the first SIM card is positioned so that the first set of contact points contact the fourth set of contact points on the inner wall, and the resilient pins on the inner wall pass through the first set of openings to contact the third set of contact points on the battery;
• wherein if the user operates the communication equipment by use of the second SIM card replacing the first SIM card, the user rotates the circumference of the disc exposed outside the casing, until the second SIM card is positioned so that the second set of contact points contact the fourth set of contact points on the inner wall, and the resilient pins on the inner wall to pass through the second set of openings to contact the third contact point.
