Abstract

The present invention provides a switch that is equipped with a driving device for establishing electrical connection and adapted to a power supplying apparatus, and a power supplying apparatus provided with the same. The power supplying apparatus has a main body, an output port, a voltage-selecting circuit and a switch for commanding the voltage selecting circuit to select the output voltage that is to be output via the output port. The switch has a plurality of resilient conductive terminals and at least one driving device. The insertion of a driving device will selectively establish electrical connection among some of the resilient conductive terminals, enabling the switch to form a circuit for adjusting the output voltage of the power supplying apparatus.

Claims

1. A switch equipped with a driving device for establishing electrical connection and adapted to a power supplying apparatus, where the power supplying apparatus comprises a main body including an output port for outputting a selected output voltage out of a plurality of predetermined output voltages and a voltage selecting circuit built in the main body and electrically connected to the output port and adapted for selecting the output voltage that is to be output via the output port based on a command made by the switch, the switch comprising:

a plurality of resilient conductive terminals extending in a longitudinal direction, each having a conductive contact portion; and

at least one driving device configured to be movable relative to the resilient conductive terminals along a direction parallel to the longitudinal direction from a start position, where the driving device is away from the resilient conductive terminals, to a predetermined driving position, where at least two of the conductive contact portions of the resilient conductive terminals are driven by the driving device to be electrically connected with each other;

wherein the driving device comprises;

a non-conductive body in a form of a card; and

a conductive part in a form of a layer of conductive material coated on the non-conductive body and for establishing electrical connection between the at least two of the conductive contact portions of the resilient conductive terminals.

2. The switch according to claim 1, further comprising a dielectric housing for accommodating at least part of the resilient conductive terminals.

3. The switch according to claim 2, wherein the dielectric housing is formed with an insert slot for receiving the driving device, the insert slot being oriented at an angle with respect to the longitudinal direction.

4. The switch according to claim 3, further comprising a latching/ejecting device for holding the driving device at the predetermined driving position as the driving device reaches the predetermined driving position, and for moving the driving device toward the start position until the driving device reaches at least a predetermined distance away from the predetermined driving position when the driving device held at the predetermined driving position is subsequently pushed inwardly.

5. The switch according to claim 4, wherein the latching/ejecting device comprises a push rod and an elastic member for driving the push rod.

6. A power supplying apparatus, comprising:

a main body including an output port for outputting a selected output voltage out of a plurality of predetermined output voltages;

a voltage selecting circuit built in the main body and electrically connected to the output port; and
