Electrical connection for combination instrument - has component contacts inserted through circuit board cooperating with auxiliary contact at rear

摘要

The electrical connection used between an electrical component and a circuit board uses openings in the circuit board receiving the component contacts (4), cooperating with flexible auxiliary contacts (6) in the rear side of the circuit board. Pref. the component is provided by a measuring device, a buzzer or a relay, the auxiliary contacts provided by wire or stamped metal elements in the form of a meandering loop. ADVANTAGE - Allows relatively low-cost, single-sided circuit board to be used.
