A contact spring for an electrical bush contact includes bottom and top springs. The bottom spring has a boxlike housing as a spring arm base with two wide sides, two narrow sides and two opposite ends. The bottom spring has a connection part integrally adjoining one of the ends of the spring arm base, at least two independent resilient contact tongues disposed on each of the wide sides of the bottom spring at the other of the ends of the spring arm base, the contact tongues being angled relative to one another for defining an insertion funnel and touching one another in a position of repose, and additional side tongues disposed on each of the narrow sides of the bottom spring. The top spring is form-lockingly held on the bottom spring and encloses and fits over the spring arm base and the contact tongues of the bottom spring boxlike on four sides. The top spring has wide and narrow sides, spring buckles disposed on the wide sides of the top spring for urging the contact tongues of the bottom spring toward one another and spring buckles disposed on the narrow sides of the top spring and associated with the side tongues.
