Digitran VLP® Rotary Switches Qualify for Space

It is now confirmed that Digitran’s 67 Series Very Low Profile (VLP®) rotary switch has been qualified as part of new equipment developed for the habitability projects on the International Space Station (ISS). The new equipment has been delivered to the Kennedy Space Flight Center for installation into the Multi-Purpose Logistics Module (MPLM). This is a large reusable cargo module that is carried by the Space Shuttle. The MPLM safely stows supplies and equipment for delivery to and from the ISS.

Digitran’s VLP® Rotary Switches were selected for this important application because of their very light weight, small size and excellent reliability. As part of the qualification, The rotary switch passed life tests that exceeded 50,000 cycles. Digitran personnel are very proud to be part of the International Space Station effort. This marks a significant milestone in Digitran’s history and a bright future for Digitran’s VLP® Rotary Switch designs.

Digitran Launches Free Revolutionary Customer Oriented Design Aid On Its’ Website

January 19, 2007: Digitran, a leading manufacturer of Rotary Switches and Encoders, has
introduced a new revolutionary and free design tool on its’ website that greatly facilitates initial
design and new product development for designers of avionics, radios, and other electronic
assemblies that require panel mounted rotary switches or encoders.

Recognizing the designers’ need to quickly design complex rotary components, the Digitran
team created the unique EZ RotaryTM Configurator Design Tool on the website: www.digitranswitches.
com. The tool allows an engineer or designer to very quickly and easily design and

select the key parameters of a rotary switch or encoder and download a 2D or rotatable 3D color
drawing for direct insertion into their CAD system design model via AutoCad®, Pro-E®,
SolidWorks®, etc., for form and fit verification – all at no cost to the designer. A free, product specific data sheet may also be downloaded. Other switch manufacturers typically provide only
general data sheets or specifications. A sample output 3-D model is shown in the figure below
next to a photo of the actual part. The EZ RotaryTM Configurator is easy to use and can save the
designer significant design and evaluation time. A quote for the newly assigned part number
may then be immediately requested via embedded email.

This new tool designs rotary switches and encoders from Digitran’s unique and patented VLP® -
Very Low Profile series of rotary components that provide the designer with the least post panel
depth and most size and weight reduction of any rotary switch or encoder available today.

Digitran Announces Integrated Flex Circuits into Rotary Switches

Effective immediately, Kapton® flexible circuits are available as a mil spec interface option on Digitran Series 57 and 67 Very Low Profile® Rotary Switches, effectively lowering the user’s installation costs.

Used on coded and low current signals, the customer may specify the length and either solder or connector termination for the kapton circuits. Digitran’s VLP® Series Rotary switches feature the least post panel depth of any rotary switch in the aerospace and military components markets. Depths as shallow as 0.141 inches are available on Digitran’s 57 Series VLP® Rotary Switches. See www.digitran-switches.com for more details.

Digitran announces 57 Series Very Low Profile® Micro-Miniature Rotary Switches

Digitran Division of EMRISE Electronics Corporation today announced the smallest design available for the patent-pending Very Low Profile (VLP ®) rotary switches. These rotary switches feature post panel depths as low as 0.141 inches and ¼ inch diameter bushings and 1/8 inch diameter shafts. Commenting on the new product line, William J. Miller, president of Digitran stated, “These new Very Low Profile rotary switches utilize the same patent pending technology

that are used in the slightly larger Digitran 67 Series VLP® rotary switches. We’ve been able to dramatically reduce the weight, size and post panel depth of the rotary switch without sacrificing the high reliability, long life and tease-proof tactile feel of our VLP® rotary switch products. The 57 Series are available with all the configured options available for Rotary Switches: multiple decks, indexing angles, stop locations, codes and poles. They can be totally sealed for mil-spec use, and feature a variety of interface options”.

Digitran, a leading manufacturer of high reliability Digital Switches for aerospace and military electronic systems applications is announcing the availability of the Very Low Profile ^TM (VLP^®) Coded Miniature Rotary Switches. These coded rotary switches are designed for use in all panel-mounted applications where space behind the system operator panel is limited. VLP^® rotary switches save the designer up to 83% space saving over competitive designs in applications such as cockpit avionics, portable equipment, consumer electronics and other applications where ‘post panel depth’ is restricted. The switches are initially available in 8, 10, and 12 position models and may include optional connectors that can significantly reduce installation time and costs for the user. Full MIL-DTL-3786 compliant switches are now available with a 2-6 week lead-time, and sell for $39-$75, depending on model and quantities. Delivery times and prices may vary depending on configurations, options and quantities.

William J. Miller, Executive Vice President of XET Corporation said, "We are extremely proud to announce these revolutionary new rotary switch products that are based on two patent-pending designs. As electronic applications become smaller and more compact, designers and engineers require very low profile control components that provide more functionality in less space. Our Digitran VLP^® Series Rotary Switches meet that requirement. For example, the Digitran Extremely Low Profile ^TM Single Deck Rotary Switch is only 0.167 inch deep, compared to conventional single deck rotary switches with post panel depths as deep as 1.0 inch. In addition, any one of our multiple deck switches, say a 4 deck Very Low Profile ^TM, which feature additional decks as thin as 0.109 inch can directly replace a competitors single deck rotary without panel modification. This example equates to four times the functionality in much less space. Our 4 deck VLP^® Miniature Rotary Switch is less than 0.5 inches deep." (See fig. 1)

Designated the 67000 Series, these new rotary switches meet or exceed the stringent requirements of MIL-DTL-3786, and feature the same high reliability electrical contacts that are found in Digitran’s MIL-PRF-22710 Qualified Digital Switches that have been flying in most military aircraft since the 1970’s.

Fig. 1

These switches are capable of carrying 3 amps and switching 100 milliamps at 28VDC with a minimum 125,000 life cycles – up to 8 times longer than some competitive rotary switches. All Digitran switches and their components are manufactured at XET Corporation’s ISO-9001:2000 certified facilities in the U.S.A. Additional detail information may be found on Digitran’s Web site:
http://www.digitran-switches.com.

Mr. Miller continued "The Digitran marketing and engineering team has performed an excellent job identifying and solving a major problem for design engineers of today and tomorrow’s electronic systems: namely how to increase the space utilization efficiency in restricted locations like cockpit instrumentation. Using the Digitran ELP ^TM or VLP^® rotary switches allows the designer to add additional electronics or additional components in the spaces previously occupied by bulkier and heavier components, thereby increasing the functionality of the equipment and improving it’s design. These new switches are ideal for commercial and military aerospace cockpit designs, portable instrumentation, automotive cockpit instrumentation, consumer electronics, and other space starved electronics systems where the designer is looking for a competitive edge and where size and weight are always a consideration. However, so revolutionary are these patent-pending designs, we are presently discussing licensing opportunities for the designs into other products and markets. Because there is no reason to waste space in any component locations, I can envision a time when most panel mounted rotary devices will utilize this patent-pending design concept."
