Systems and techniques are provided for electrical circuit switching. An electrical load may be connected to a voltage supply with current flow entering a first terminal of the electrical load. The electrical load may be disconnected from the voltage supply. The electrical load may be connected to ground such that the electrical load discharges. The electrical load may be connected to the voltage supply with current flow entering a second terminal of the electrical load. The electrical load may be disconnected from the voltage supply. The electrical load may be connected to ground such that the electrical load discharges.
