Product development

We strive to provide products that are the best they can be. We listen to our customers and hone our designs to solve their issues.

A solution for low light settings

Checking the open and closed status of the switch poles can be difficult in low light. To solve this issue we incorporate high intensity, low current 24V LED lighting into the viewing window frame of the Koenigs visible isolator enclosure. Each LED bank is approx 50mm and draws just 18mA at 24VDC.

We also offer door-mounted cubicle lighting with simple push button ON-OFF control.

Keeping the screen clean

Visual confirmation of the position of the switch pole contacts cannot be achieved when heavy dirt and grime builds up on the Visual Isolator viewing window. Attempting to wipe the dirt away can make the problem worse. Koenigs Visual Load Break Isolators have optional spring-loaded 316SS window flaps to help prevent the build-up of dirt and grime on the viewing window. The window flaps are available for all sizes of viewing window in the Koenigs visible isolator range.
