Patent ID: 8911252

Claim:
An electrical apparatus ( 1 ) comprising: a base ( 2 ) configured to be attached to a substrate ( 4 ), a functional head ( 3 ) which has at least one electrical or electronic functional device ( 10 ), wherein the functional head ( 3 ) is attached to the base ( 2 ) with a bayonet connection ( 6 ), wherein the base ( 2 ) has a first contact ( 14 ) and the functional head ( 3 ) has a second contact ( 30 ) which are contact-connected to one another, wherein the bayonet connection ( 6 ) is configured to be formed by a relative movement of the functional head ( 3 ) in relation to the base ( 2 ) in an axial direction (A), and a subsequent relative rotation, characterized in that the first contact ( 14 ) and the second contact ( 30 ) are configured to be contact-connected to one another by the relative rotation, characterized in that the first or second contact is in the form of a resilient contact and the other contact is in the form of a fixed contact ( 30 b ) which is to be elastically received in the resilient contact ( 14 ), wherein the resilient contact ( 14 ) is of resiliently flexible design in a radial plane perpendicular to the axial direction and the fixed contact extends at least partially in the axial direction, and wherein the number of first and second contacts is identical in order to form a plurality of electrical contacts, and characterized in that the resilient contact is in the form of forked contacts ( 14 ) with two elastically flexible spring limbs ( 14 a, b ) for receiving the fixed contact ( 30 b ) which extend in the axial direction (A) and are in the form of contact blades.
