CUI Devices Introduces Several New Lines of DIP Switches

December 02, 2020 by Gary Elinoff

The new devices available include piano, slide and rotary actuator types.

The first launch of CUI Devices’ Switches Group features units with up to 16 positions. Pitches of 1.27, 2.54 or 5.08 mm are offered, as are both through hole and surface mounted styles.

What is a DIP switch?

In electronics, the term “DIP” refers to a dual in-line package. DIP switches are packaged in rectangular enclosures that connect mechanically and electrically with the PCB via two parallel rows of connection points. They are often used to configure electronic devices. 

They have been, to a degree, been replaced by remotely configurable nonvolatile memory. 

However, computer security has emerged as one of the hot-button concerns in electronics today, and hijacking the remotely configurable nonvolatile memory that controls electronic devices is one of the major routes taken by malefactors. In that context, one of the most interesting things about DIP switches is that they can’t be hijacked from thousands of miles away, but can only be manipulated by a person with direct physical access to a machine.


Flexibility is the Key

The new lines of DIP Switches offer:

  • Flat bottom or convex versions
  • Raised or flat actuator levels
  • PC pin or gull wing terminations
  • Short, long, or SMT pins


Voltage and Current Ratings

The switching voltage and switching current are the maximum voltage or current, respectively, that a switch can handle as it opens or closes. 

The non-switching voltage and non-switching current, analogously, are is the maximum voltage or current that the switch can handle in a steady state, after switching has occurred.

 The new lines of DIP switches feature:

  • Switching current: 25 or 100 mA
  • Non-switching current: 100 or 400 mA
  • Switching voltage: 24 or 42 Vdc
  • Non-switching voltage: 42 or 50 Vdc


The New Products

There are 18 new series of devices in the current launch, including 1, 12, and 5 of piano, rotary and slide types, respectively.

The DS02-254 is the only series of the piano actuator type.

Series members are available with 2 to 12 positions. They operate over a temperature range of 

-40 to 85℃.

The RDS-1045 series is one of the twelve series composed of rotary actuators.

Members are through-hole mounted and have either 10 or 16 positions. Pitch is 2.54 mm.

The DS05-127-SMT-TR is one of the five series of slide actuators

CUI Devices provides a Parametric Search page where engineers can search for the criteria relevant to their specific design needs.



The new DIP switches will find application in

  • Telecommunications
  • The IoT 
  • Industrial environments
  • The commercial area


Physical and Environmental Considerations

  • RoHS compliant
  • Qualified to the UL94V-0 flammability rating 
  • Qualified to 1067 for moisture and environmental contaminants


About CUI Devices

Last year, some now-former senior managers of CUI Inc formed a group to purchase the company’s components business to form a new entity, CUI Devices. The acquisition included existing interconnect, thermal management, sensor, motion and audio product lines.

"The CUI Devices management team strongly believes in this business and is confident in its future prospects as a stand-alone entity," said Matt McKenzie, CEO of CUI Devices. "We have dedicated many years to building CUI Inc, and we look forward to guiding the company to even greater success as a free-standing company." 

At the time of the announcement, the new organization took pains to assure existing customers of continuity. The current launch is one of the largest since the change.
