A switch for a medium voltage or high voltage switchgear, comprising:

• a first fixed contact;
• a second fixed contact;
• a moveable contact;
• at least one flexible link;
• and
• a contact drive,
• wherein, in an on state of the switch, the moveable contact is in a position that connects the first fixed contact to the second fixed contact,
• wherein, in an off state of the switch, the moveable contact is in a position where the first fixed contact is not connected to the second fixed contact,
• wherein the at least one flexible link is connected to the moveable contact,
• wherein the at least one flexible link is configured to engage with the contact drive, the contact drive being configured to pull the moveable contact via the at least one flexible link and to push the moveable contact via the at least one flexible link,
• wherein activation of the contact drive in a first mode is configured to move the moveable contact to a position such that the switch is in the on state,
• wherein activation of the contact drive in a second mode is drive is configured to move the moveable contact to a position such that the switch is in the off state,
• wherein the contact drive comprises at least one cog wheel configured to engage with the at least one flexible link,
• wherein the at least one flexible link comprises two flexible links,
• wherein the at least one cog wheel comprises two cog wheels,
• wherein rotation of a first cog wheel of the two cog wheels in a first direction is configured to pull a first flexible link of the two flexible links and rotation of a second cog wheel of the two cog wheels in a second direction counter to the first direction is configured to pull a second flexible link of the two flexible links, and
• wherein rotation of the first cog wheel in the second direction is configured to push the first flexible link and rotation of the second cog wheel in the first direction is configured to push the second flexible link.
