The contact clamp (20) includes a base (21) secured to the back cover of a case on one side of a push-button (10) and an elastic strip (22) extending beyond the push-button of which a first pre-stressed portion (23, 24) forms the key and return spring and a second portion (25, 26, 27) of greater flexibility allows, at its end (28), a contact to be closed with less force than that which has to be exerted on the push-button.
