Abstract:
1. A method for operating a switching device with a power supply and a switching element, the method comprising: supplying the power supply with an external supply voltage, an external user being connected to the switching element, an operating voltage generated by the power supply being supplyable to the user with the switching element via an outgoing operating voltage line from the power supply, and the power supply including at least one electrical energy storage medium connected between an operating voltage line and a reference potential; and energizing the user for a short term by activation of the switching element, when the user is switched off, from the energy stored in the at least one electrical energy storage medium, wherein the short-term energization occurs during a discharge time, and a duration of the discharge time is matched to a storage capacity of the energy storage medium on the one hand and to an inertia of the user on another hand.
