## Abstract

A contact switch including a rail having slot with a first straight section and a second curved section, a toggle unit inside a housing, the toggle unit including an extension unit that slidably engages the slot and at least one contact, a contact unit in the housing including at least one contact, where the toggle unit moves in the housing such that the contacts on the toggle unit engage at least one contact on the stationary unit in the first straight section and the contacts disengage in the second curved section.

## Claims

### Claim 1

A contact switch including:
a rail having a slot with a first straight section and a second curved section;
a toggle unit inside a housing, the toggle unit including an extension unit that slidably engages the slot and at least one contact;
a stationary unit in the housing including at least one contact;
wherein the toggle unit moves in the housing such that the at least one contact on the toggle unit engages the at least one contact on the stationary unit in the first straight section and the at least one contact on the toggle unit disengages the at least one contact on the stationary unit in the second curved section, and
wherein the at least one contact on the toggle unit includes two contacts affixed to a back surface of the toggle unit with the two contacts being offset from one side of the back surface.

### Claim 2 (depends on 1)

The contact switch of claim 1 wherein the at least one contact on the stationary unit includes four contacts.

### Claim 3 (depends on 1)

The contact switch of claim 1, wherein the housing includes a pin that engages an opening on the stationary unit.

### Claim 4

A glove compartment switch including:
a gear;
a rail connected to the gear, the rail having a slot with a first straight section and a second curved section;
a toggle unit inside a housing, the toggle unit including an extension unit that slidably engages the slot and at least one contact;
a stationary unit in the housing including at least one contact;
wherein the toggle unit moves in the housing such that the at least one contact on the toggle unit engages the at least one contact on the stationary unit in the first straight section and the at least one contact on the toggle unit disengages the at least one contact on the stationary unit in the second curved section, and
the at least one contact on the stationary unit connected to a second set of contacts positioned on one side of the rail.

### Claim 5 (depends on 4)

The glove compartment switch of claim 4 wherein the at least one contact on the toggle unit includes two contacts affixed to a back surface of the toggle unit with the two contacts being offset from one side of the back surface.

### Claim 6 (depends on 5)

The glove compartment switch of claim 5 wherein the at least one contact on the stationary unit includes four contacts.

### Claim 7 (depends on 4)

The glove compartment switch of claim 4 wherein the toggle unit includes an extension unit on a bottom surface with the extension unit being sized to engage a groove extending along the length of the rail.

### Claim 8 (depends on 7)

The glove compartment switch of claim 7 wherein the extension unit passes through a slot in a bottom portion of the housing.

### Claim 9 (depends on 4)

The glove compartment switch of claim 4 wherein the at least one contact on the stationary unit includes two contacts.

### Claim 10 (depends on 9)

The glove compartment switch of claim 9 wherein the housing includes a pin that engages an opening on the stationary unit.

### Claim 11 (depends on 4)

The glove compartment switch of claim 4 including a cover on the housing.

### Claim 12 (depends on 4)

The glove compartment switch of claim 4 wherein the at least one contact on the stationary unit includes a first contact on a first side of the stationary unit and a second contact on a second side of the stationary unit opposite the first contact.
