A contacting device has a housing in which a first contact element is arranged. The first contact element has a receiving chamber for a second contact element, which is open with respect to at least one opening of the housing. The first contact element is displaceable relative to the housing in a direction transverse to a central longitudinal axis of the receiving chamber against a spring element, so that the second contact element is insertable into the receiving chamber and capable of being clamped in the receiving chamber by the spring element. The first contact element is firmly connected to at least one plug-in contact element. By this device, a transmission of electrical energy from a power supply line to a circuit board can be achieved in simple and reliable manner.
