RIVERSIDE, Calif., Aug. 23, 2011 /PRNewswire/ — Bourns, Inc., a
leading manufacturer and supplier of electronic components, today
announced two new industrial-grade panel control models that
include a push-pull switch and rotary switch. Designated the
Bourns® Model 54, the new 1/2-inch panel control is an
extension of Bourns® Model 51/53 Series with an added
double-pole, double-throw (DPDT) push-pull switch module. The
Bourns® Model 56 is a new 1/2″ panel control and is also an
extension of the Bourns® Model 51/53 Series with an added
single-pole, double-throw (SPDT) rotary switch module. Both
new products are high-performance alternatives to readily available
consumer-grade potentiometers with push-pull and rotary switches.
Developed to match the requirements of a broad range of
industrial, medical and aerospace/avionics applications, Bourns’
new panel control models are particularly well-suited for use in
test and measurement and communications equipment.
Bourns® Model 54 is also an optimal solution for medical
diagnostic and professional audio equipment, while the Bourns®
Model 56 is designed for use in avionics controls and medical
laboratory equipment.
The new models measure 12.5 mm and feature metal bushings and
shafts, splash seals and a wide range of linear and audio
resistance tapers. Rotational life for both models is 50k
cycles with contact resistance at 100 m(omega) for Model 54 and 30
m(omega) for Model 56. Both models are RoHS compliant.*
“Bourns’ new industrial grade panel controls are significant
because they provide the flexibility of a panel control plus
push-pull switch or rotary switch in one compact component.
In addition, the splash seal provides protection from
moisture ingression in a wide variety of applications,” said Chuck
Manzano, Product Specialist for Bourns, Inc. “The new panel
controls provide designers with high-performance alternatives
