1. A transformer assembly for an aerosol-generating system, the transformer assembly comprising:
a magnetic flux guide;
a primary circuit including a primary winding extending around a first portion of the magnetic flux guide and electrically connected to a power supply; and
a secondary circuit inductively coupled to the primary winding and extending around a second portion of the magnetic flux guide, the secondary circuit including at least two electrical contact blades and an electrically conductive track electrically connecting the electrical contact blades, wherein each of the at least two electrical contact blades has a pointed leading edge configured to form an electrical connection with a heating element.
