Reliance Controls Corporation began as "Reliance Automatic Lighting Company" in 1909 with the invention of the heavy-duty commercial time switch.
|
|
|
1909
|
The first “RELIANCE” time switch was an eight-day, spring-wound clock-operated switch that would automatically control lighting for
apartment houses, store windows and electric signs on a daily schedule. The growing electrical industry found more and more applications
for Reliance time switches and the company expanded rapidly.

|
|
1923
|
In 1923 Reliance introduced the “ACE” self-winding time switch. This remarkable design incorporated an electric motor that would actually wind the clock spring automatically.
This was the first Reliance time switch that did not have to be wound on a weekly basis.
|
|
|
1930
|
In the 1930's, Reliance pioneered the synchronous motor-driven time switch trend with the heavy-duty "BADGER" series.
|
|
|
1969
|
In 1969 Reliance introduced the compact and rugged Series 500 time switches. The Series 500 has been used on billboards, water heaters, lighting and any
place electrical power needs to be controlled on a daily schedule. Today the Series 500 is the quality standard for the industry.
|
|
|
1983
|
In 1983, Reliance introduced the first manual transfer switches engineered specifically for use with portable generators of up to 5000W.
|
|
|
1995
|
In 1995, Reliance Controls Corporation introduced Panel/Link® manual transfer panels (pictured on the right)...
...and generator-ready load centers for use with standby generating systems to 31.5kW (pictured on the left).
Today the Panel/Link Series encompasses over 300 models including 3-phase and prewired panels.

|
|
1999
|
In 1999, Reliance Controls Corporation introduced the Easy/Tran® for use with traffic signals, cell towers, irrigation systems, community well pumps and more. The Easy/Tran is the original “point-of-use” transfer switch.
|
|
|
2003
|
In 2003, the original Reliance Gen/Tran(TM) line of manual transfer switches was replaced with the vastly improved Pro/Tran® Series which accommodates portable generators of up to 12,500W.
The Pro/Tran® is also the first loadside transfer switch to be listed to the new, and more stringent, UL1008 standard.
|
|
|
2005
|
In 2005, Reliance Controls Corporation added the Pro/Tran® Q Series. The Q is a totally unique loadside transfer switch featuring conventional 1-inch interchangeable circuit breakers for
easy upgrading and adjusting of branch circuit protection on the generator side of the transfer switch. It is ideal for heavier residential loads such as water heaters, deep well pumps, septic lift stations and central air conditioners.
The Q Series is available with the exclusive Reliance electronic bar graph meter which monitors voltage and wattage on each generator leg.
