Electrical switching arrangement

An electrical power supply for supplying an output voltage to a load, the electrical power supply comprising:

• one or more capacitors for generating a voltage, wherein the one or more capacitors comprise:
• a live terminal and a ground terminal;
• and
• an electrical switching arrangement for connecting the voltage generated by the one or more capacitors to the load, wherein the electrical switching arrangement comprises:
• a live conductor connected to the live terminal of the capacitor, wherein the live conductor comprises a set of electrodes for switching between a first side of the live conductor and a second side of the live conductor;
• a ground conductor connected to the ground terminal of the capacitor;
• an insulation block between the set of electrodes and the ground conductor;
• a first insulation member extending from the insulation block on the first side of the set of electrodes;
• and
• a second insulation member extending from the insulation block on the second side of the set of electrodes;
• wherein the insulation block comprises a first groove in which an edge of the first insulation member is located and a second groove in which an edge of the second insulation member is located.
