Abstract
An example embodiment relates to a method for switching a current in an electromagnet of a switchable solenoid valve, wherein, in successive switching cycles, the current is in each case switched on in order to close the valve against a force of a spring, and thereby the current is generated by electrical connection of the electromagnet to a voltage source. The example embodiment makes provision for the current in the electromagnet to be generated with a current direction opposite to the respective previous switching cycle in at least two successive switching cycles in a switched operation of the valve.
