The electrical receptacle comprises a formed resilient metal leaf spring member received in a through passage defined by bottom, side and top walls in a plastics supporting housing. The through passage has an inclined portion in its top wall for contacting the spring member. The spring member is formed with an arc in its central portion, the arc having a nonflexing hump formed there and flat length continuing to serve as a stop against the bottom wall of the passage. The spring member is secured in the through passage, with its central arc portion contacting the inclined portion of the through passage in the receptacle. This elastically deforms the arc portion of the spring to preload the spring.
