Digitran Custom Designed Rotary Switch Examples

Digitran builds Custom Rotary Switch Solutions. Working closely with our customer requirements we are able to provide customized switching solutions utilizing our experienced Engineers to provide the right solution. Below are some of the challenging rotary switch designs we have provided for some of our customers.

Contact us to discuss your applications today.

A rotary switch with precision timing on/off sequence through it's 72 degrees of travel across 6 poles; Medium Current, Small Space Customer required a long-life switch that would accurately switch high inductive current across multiple poles with tolerances less than 1.5 degrees of arc.

Digitran’s engineering, using exclusive VLP® technology, solved the problems associated with contact erosion associated with high currents, and still achieved ±1.5-degree electrical contact timing over the life of the switch.


Power potentiometer and rotary switch features tensioned manual override stops for precision control.



A single turn 260-degree, 5-Watt potentiometer, integrated into a reliable rotary switch gives the operator repeatable setting to highly sensitive control. Dual spring return action integrated into the shaft can be manually over-ridden in CW or CCW motion. This switch also required a panel seal. Because our bushings are one piece, we can seal shaft and panel with "O' rings to meet panel seal requirement.

69-Series Rotary

Family of rugged rotary switches with various features such as push and pull momentary switches and mechanical isolations for entering and exiting.

A series of similar sized switches some with Push to turn, some are rotary only, some have stops, others like the one show have a momentary push and pull feature combined with a coded output rotary switch. You can actuate the push or pull feature in any position.

This switch also has Digitran's one-piece stainless steel threaded bushing which is grooved for an "O" ring panel seal. These switches are built rugged to withstand the constant vibration associated with their intended use on military aircraft.

Space Application


Space the Final Frontier...

In Orbit, Digitran's solutions for space are reliable, lightweight, customized switches designed for the challenging environment of space.

Our first space solution was launched on November 15th, 2008, aboard the Space Shuttle Endeavor on its way to the International Space Station. This lightweight rotary switch is actuated repeatedly every day as part of the Potable Water Dispenser and allows an astronaut to select the volume of hot or cold water needed to rehydrate food and drink mixes.

Digitran has recently completed another rotary switch bound for space on future crew capsule missions. Crews heading for space are counting on Digitran's Reliability.
