Contact spring having an improved electrical contact

摘要

A handheld transmitter has a housing in which there are disposed a printed circuit board and a battery. The circuit board and the battery are electrically connected by a contact spring. The contact spring has two preshaped spring arms each on its two ends, which are elastically braced against the printed circuit board and against the battery. The contact spring ensures that the battery and the printed circuit board are at all times securely connected electrically without being subject to disconnection caused by shaking the handheld transmitter.
