## Abstract

A detection switch for detecting when a card is inserted in to a connector. The detection switch includes a housing, a shell, a card receiving passageway, and a detection switch. The shell is disposed on and covers the housing. The card receiving passageway is arranged between the housing and the shell. The detection switch detects when the card is inserted into the card receiving passageway and disposed along a side of the card connector. The detection switch includes a fixed contact secured to the housing, and a movable contact extending from the shell and configured to (1) contact the fixed contact when the card is not inserted in the card receiving passageway and (2) release from contact with the fixed contact when the card is inserted into the card receiving passageway.

## Claims

### Claim 1

A connector for receiving a card, the connector comprising:
a housing;
a shell disposed on and covering the housing;
a card receiving passageway arranged between the housing and the shell; and
a detection switch for detecting when the card is inserted into the card receiving passageway and disposed along a side of the connector, the detection switch having:
a fixed contact secured to the housing and having a point corner portion; and
a movable contact extending from the shell and configured to (1) contact the point corner portion of the fixed contact when the card is not inserted in the card receiving passageway and (2) release from contact with the point corner portion of the fixed contact when the card is inserted into the card receiving passageway.

### Claim 2 (depends on 1)

The connector according to claim 1, wherein the housing is substantially rectangular.

### Claim 3 (depends on 1)

The connector according to claim 1, wherein the fixed contact includes a flat plate secured portion secured to the housing and extending in width and length directions of the housing.

### Claim 4 (depends on 3)

The connector according to claim 3, wherein the fixed contact further includes a fixed contact piece extending outward and obliquely upward from a side portion of the flat plate secured portion.

### Claim 5 (depends on 4)

The connector according to claim 4, wherein the shell includes (1) a planar portion covering a top surface of the housing and (2) a side surface portion extending downward from a side surface of the planar portion and covering a side surface of the housing.

### Claim 6 (depends on 5)

The connector according to claim 5, wherein the movable contact includes a cantilever movable contact piece extending obliquely inward from the side surface portion of the shell.

### Claim 7

A detection switch for detecting insertion of a card into a card receiving passageway of a connector, the detection switch having:
a fixed contact secured to a housing of the connector and having a point corner portion; and
a movable contact extending from a shell of the connector and configured to (1) contact the point corner portion of the fixed contact when the card is not inserted in the card receiving passageway and (2) release from contact with the point corner portion of the fixed contact when the card is inserted into the card receiving passageway.
