Abstract
Described is a pressure measuring glow plug with a housing, a glow pin, which projects out of the housing and can be displaced in its longitudinal direction relative to the housing against a restoring force. A sensor acquires the position of the glow pin or a pressure acting on the glow pin, and a center pole is arranged in the housing and electrically connected to the glow pin via a contact spring. This disclosure provides that the contact spring is a U-shaped, bent metal strip, which in a middle section has a reduced width, and broadens from the middle section toward its two ends.
