An electrical apparatus such as a switch comprises a housing and a push-button. A spring-loaded catch mechanism holds the push-button alternately in a rest position and in a working position for which the push-button protrudes more or less from the housing. The catch mechanism comprises a catching lever which is mounted through an integral pivot accommodated in a hole of a wall of the housing and which has a depressed area receiving a pin carried by a wall of the push-button. The depressed area is bounded by ramps which are successively engaged by the pin for oscillating the catching lever about its pivot. A resilient finger, integral with the catching lever, brakes the latter by pressing against the wall of the housing. The catching lever, the housing and the push-button are made of plastic material.
