VIVISUN® Lighted Pushbutton Switches

NEXSYS Component Options - Switch Body

NEXSYS® Component Technology is available in our VIVISUN® High Capacity or Compact switch bodies, as well as in NEXSYS® Modules. Each NEXSYS component is either a 4-pin device (shown in green) or an 8-pin device (shown in orange) and can occupy a position inside the body that is not already occupied by an electromechanical switch or other NEXSYS component.

High Capacity Body

High Capacity bodies with either a Standard Square or Large Rectangular cap have four available, 4-pin positions (H, J, K and L in the diagram below). Each 4-pin NEXSYS component or electromechanical switch will occupy one of the available four positions.

High Capacity bodies can accommodate one 8-pin NEXSYS component that will occupy the middle two positions, leaving position H and L available for either two 4-pin NEXSYS components, two electromechanical switches or one of each as shown in the example diagram. High Capacity bodies can also be configured with 4 electromechanical switches w/o NEXSYS Component Options.

Unoccupied positions will be configured with an Open spacer. High Capacity bodies with NEXSYS components require the use of Connector Plug (P/N 18-440).

High Capacity Component Options
Up to four NEXSYS components
in a High Capacity Body

Example: Standard Square, High Capacity Body with;
one electromechanical switch, one 8-pin component
and one 4-pin component

Example: Large Rectangular, High Capacity Body with;
one electromechanical switch
and three 4-pin components

Compact Body

Compact bodies with either a Standard Square or Large Rectangular cap have two available, 4-pin positions (A and B in the diagram below). Each 4-pin NEXSYS component or electromechanical switch will occupy one of the available two positions. Compact bodies can also be configured with 2 opens (indicator) or 2 electromechanical switches. See Switch Body Options.

Unoccupied positions will be configured with an Open spacer.

Compact bodies cannot accommodate an 8-pin NEXSYS component. Configurations that require the use of an 8-pin NEXSYS component must use a High Capacity body.

Compact bodies with NEXSYS components require the use of Connector Plug (P/N 18-442).

Compact Component Options
Up to two NEXSYS components
in a Compact Body

Example: Standard Square, Compact Body with;
two 4-pin components

Example: Large Rectangular, Compact Body with;
one 4-pin component and one open spacer
