In one embodiment, a switch system includes: an actuator connected to a sliding cam for moving the sliding cam between a first position and a second position, the sliding cam slidingly receiving a terminal blade of the utility meter and including a pair of camming surfaces for disengaging a pair of conductors from the terminal blade in response to being moved from the first position to the second position by the actuator. ## Claims ### Claim 1 A switch system for a utility meter, the switch system comprising: an actuator connected to a sliding cam for moving the sliding cam between a first position and a second position, the sliding cam slidingly receiving a terminal blade of the utility meter and including a pair of camming surfaces for disengaging a pair of conductors from the terminal blade in response to being moved from the first position to the second position by the actuator, wherein the pair of camming surfaces are each disposed at a first angle relative to an axis of sliding of the sliding cam, and wherein the pair of conductors each include an angled end portion for contacting the pair of camming surfaces, each of the angled end portions being disposed at a second angle, the second angle being greater than the first angle relative to the axis of sliding, wherein the sliding cam is configured to substantially enclose a portion of the terminal blade. ### Claim 2 (depends on 1) The switch system of claim 1, further comprising a pair of transfer components physically connected to the sliding cam via a pin, wherein the pair of transfer components are configured to pivot about the pin and adjust a position of the pair of conductors. ### Claim 3 (depends on 2) The switch system of claim 2, further comprising a distribution bar operatively connected to the actuator and the sliding cam, the distribution bar adapted to transfer a force from the actuator to the sliding cam. ### Claim 4 (depends on 1) The switch system of claim 1, wherein the pair of conductors are spring conductors. ### Claim 5 (depends on 1) The switch system of claim 1, wherein the actuator includes a service switch with an off position and an on position. ### Claim 6 (depends on 4) The switch system of claim 4, wherein the service switch includes a receiver for receiving instructions for changing a position of the service switch. ### Claim 7 (depends on 1) The switch system of claim 1, wherein the sliding cam is configured to move in a vertical direction about the terminal blade. ### Claim 8 (depends on 3) The switch system of claim 3, wherein at least one of the sliding cam, the set of transfer components, the distribution bar, and the pin are nonconductive. ### Claim 9 A switch system for a utility meter, the switch system comprising: an actuator connected to a sliding cam for moving the sliding cam between a first position and a second position, the sliding cam slidingly receiving a terminal blade of the utility meter and including a pair of camming surfaces for disengaging a pair of conductors from the terminal blade in response to being moved from the first position to the second position by the actuator, wherein the pair of conductors each include a main body disposed non-parallel relative to one another, wherein the sliding cam is configured to substantially enclose a portion of the terminal blade. ### Claim 10 (depends on 9) The switch system of claim 9, further comprising a pair of transfer components physically connected to the sliding cam via a pin, wherein the pair of transfer components are configured to pivot about the pin and adjust a position of the pair of conductors. ### Claim 11 (depends on 10) The switch system of claim 10, further comprising a distribution bar operatively connected to the actuator and the sliding cam, the distribution bar adapted to transfer a force from the actuator to the sliding cam. ### Claim 12 (depends on 9) The switch system of claim 9, wherein the pair of conductors are spring conductors and wherein the actuator includes a service switch with an off position and an on position and wherein the service switch includes a receiver for receiving instructions for changing a position of the service switch. ### Claim 13 (depends on 9) The switch system of claim 9, wherein the sliding cam is configured to move in a vertical direction about the terminal blade. ### Claim 14 A switch system for a utility meter, the switch system comprising: an actuator connected to a sliding cam for moving the sliding cam between a first position and a second position, the sliding cam slidingly receiving a terminal blade of the utility meter and including a pair of camming surfaces for disengaging a pair of conductors from the terminal blade in response to being moved from the first position to the second position by the actuator, wherein the pair of camming surfaces are adapted to remain in contact with the pair of conductors when moved from the first position to the second position. ### Claim 15 (depends on 14) The switch system of claim 14, further comprising: a pair of transfer components physically connected to the sliding cam via a pin, wherein the pair of transfer components are configured to pivot about the pin and adjust a position of the pair of conductors; and a distribution bar operatively connected to the actuator and the sliding cam, the distribution bar adapted to transfer a force from the actuator to the sliding cam. ### Claim 16 (depends on 14) The switch system of claim 14, wherein the pair of conductors are spring conductors. ### Claim 17 (depends on 14) The switch system of claim 14, wherein the actuator includes a service switch with an off position and an on position and wherein the service switch includes a receiver for receiving instructions for changing a position of the service switch. ### Claim 18 (depends on 14) The switch system of claim 14, wherein the sliding cam is configured to move in a vertical direction about the terminal blade.
