## Abstract

A universal slot disposed on a base plate includes a first slot and a second slot. The first slot has a first electrical characteristic, and the second slot has a second electrical characteristic. The second slot covers the first slot in appearance.

## Claims

### Claim 1

A universal slot disposed on a base plate, the universal slot comprising:
a first slot having a first electrical characteristic corresponding to the first slot and a plurality of first metal elastic members disposed correspondingly to the first electrical characteristic, the first slot further comprising a first opening located at a first height;
a second slot having a second electrical characteristic corresponding to the second slot and further comprising a second opening located at a second height, wherein the first slot is disposed in the second slot, the first opening and the second opening are located on a same plane which is perpendicular to the base plate, and the second slot further comprises a plurality of second metal elastic members disposed correspondingly to the second electrical characteristic; and
a supporting structure having at least one stress point disposed at the bottom of the first slot and at least one supporting portion disposed correspondingly to the second metal elastic members, and when an external force is applied to the stress points downward, the supporting portion opens the second metal elastic members toward two sides.

### Claim 2 (depends on 1)

The universal slot according to claim 1, wherein the second slot covers the first slot, and the second opening and the first opening have a same opening direction which is perpendicular to the base plate.

### Claim 3 (depends on 1)

The universal slot according to claim 1, wherein the second height is higher than the first height.

### Claim 4 (depends on 1)

The universal slot according to claim 1, wherein the first slot corresponds to the electrical characteristic of PCI Express X1/X4, and the second slot corresponds to the electrical characteristic of PCI.

### Claim 5

A universal slot disposed on a base plate, the universal slot comprising:
a first slot having a first electrical characteristic corresponding to the first slot and a plurality of first metal elastic members disposed correspondingly to the first electrical characteristic, the first slot further comprising a first opening located at a first height;
a second slot having a second electrical characteristic corresponding to the second slot and further comprising a second opening located at a second height, wherein the first slot is disposed in the second slot, the first opening and the second opening are located on a same plane which is perpendicular to the base plate, and the second slot further comprises a plurality of second metal elastic members disposed correspondingly to the second electrical characteristic; and
a pushing structure having a lever switch disposed at one end of the second slot and a plurality of pushing portions disposed correspondingly to the second metal elastic members and connected to the lever switch via a connecting portion, and when the lever switch is pressed, the pushing portions pushes upward and opens the second metal elastic members.
