Switching and control range Jung LS 990 wall switch series LS 990, modular design, brand JUNG
Jung LS 990 is a modular wall switch and control range by JUNG designed for electrical switching and user control in residential and commercial interiors. The series features a minimalist, modular design that fits standard wall boxes and supports a variety of rocker, push and push-button modules. The product family is intended for lighting control, power switching and integration with building installations where a consistent visual appearance and modular compatibility are required.
The LS 990 range offers a modular concept that allows flexible combination of switch and control modules in one frame. Its minimalist aesthetic provides a neutral appearance compatible with modern interiors. The design supports specific variants including rocker switches, illuminated rocker options (using a rocker with lens), push switches and multi push-button modules, plus a spare holder plate for installation and replacement. The modular approach simplifies maintenance and partial replacement of individual modules without changing the complete frame.
Install the LS 990 modular modules into a standard wall box using the compatible holder plate and frames. Select the appropriate module type for the intended function: rocker modules for on/off switching, illuminated rockers when local indication is required, push switches or push-buttons for momentary control and multi push-button modules for multi-function control. Electrical connections should be made by a qualified electrician following applicable wiring regulations and the manufacturer’s installation instructions. For illuminated inserts, install the rocker with lens specified for illuminated operation.
For reliable operation and compliance with local standards, fit modules into standard mounting boxes and secure them with the specified holder plate. Use the module reference numbers to select compatible parts and keep spare holder plates available for maintenance. Ensure illuminated modules are connected according to the installation guide to prevent incorrect wiring and to maintain indication functionality.
