Our success and company history

Elevating Industry

Dupar is one of the most advanced companies in North America specializing in Elevator Fixtures and is continually investing in innovation, design and manufacturing automation to meet our Customers ever-changing requirements. Founded in 1958 Dupar Controls Inc. is recognized as the world leader in Elevator push-button technology.

Dupar is probably best known for its wide range of high quality pushbutton products. Although we have been making pushbuttons for a long time, a breakthrough was made in 1971 with the launch of the US81 Original Pushbutton. This really was a unique design, which began a styling of chrome surround with a stainless pressel that has been imitated (but never matched) by many others. Following on from the success of the US81 the company has since focused heavily on Pushbuttons and Fixture products and now has a wide and very popular range of Braille, B44-00 & ANSI Pushbuttons.

As well as having a significant presence in the elevator industry, Dupar is also a major player in the keypad industry and supplies a wide range of products for the ATM industry.

Recently Dupar has completed a major plant expansion doubling our factory and office facilities. This has allowed us to acquire additional automated equipment operating on two full shifts.

Utilizing state of the art in-house design and CAD technology, Dupar provides an extremely quick turn-around in producing approval drawings for your Custom requirements. From receipt of order, Dupar provides full integration between your final approved drawing, order entry into our Manufacturing System that is integrated with fully automated Trumpf Laser Cutting, CNC Punching, CNC Engraving & CNC Studding.

Here at Dupar we are all part of the Customer Services Team and we strive to provide Exceptional service.

Over A Century of Dewhurst History


The company was founded in November 1919 by Melbourne Dewhurst and Howard Marryat known then as Dewhurst & Partner.

Starting off in a small repair shop in Hatton Garden and later moving to a new premises in Inverness Road.  It was from here, single-handed, Melbourne Dewhurst developed a wide range of designs based on his technical knowledge and practical experience which based the future manufacturing development of the company.


After the war considerable expansion took place for a 10 year period – a seller’s market gave a wonderful opportunity to enlarge  and extend the manufacture of control equipment for cranes and machine tools.

Significant expansion took place at the Inverness Road site and the total number of employees towards the end of 1950’s was approximately 800 people.

1960’s to 1990

In 1962 Alan Dewhurst took over as Chairman and in the late 1960’s and 70’s was the start of the new period of process innovation with the introduction of moulding and stainless steel colouring, as well investment in NC sheet metal equipment.

In 1976 we won a Design Council Award for the vandal resistant lift pushbutton and this signalled a major advance in this range of products, which proved to have a wide market both at home and overseas.  This vandal resistant development extended into the rail and ATM market for London Underground and NCR for ATM keypads.

The Recent Years

In our 75th year, we bought Thames Valley Lift Company.  Richard Dewhurst took over as Chairman and the company entered into a new period of expansion.  It could be said that it has been reborn again in the last 15 years.  The biggest change during this period has been to extend the geographical and product spread of the business.

In the last 15 years the Group has gone from a business at Hounslow with one Canadian subsidiary to a global business with over a dozen operating subsidiaries over 4 continents.

Dewhurst Group Worldwide

We are proud to be part of the Dewhurst Group which operates across four continents, supplying quality components to the lift, transport, and keypad industries
