A thick film polymer membrane switch can be positioned within a seat belt buckle. The switch can detect if the seat belt buckle is fastened or unfastened. In one approach, an apparatus includes a housing having a cavity, an insertion member moveable within the cavity, a connector positioned within the cavity, and a switch positioned within the cavity, wherein movement of the insertion member causes the connector to connect or disconnect from the switch. In some approaches, the switch includes a first conductive element formed adjacent a first layer of flexible film, and a second conductive element formed adjacent a second layer of flexible film, wherein the first and second layers of flexible film are separated by a gap.
