As Switzerland’s only manufacturer, we are specialised in the production of door closers. We are continuously optimising and expanding our product range; our strengths thus always remain the same: Efficient production and an intelligent design allow an excellent price/performance ratio. And the market proximity as a small business guarantees our customers a smooth service and individual consulting. Our motto: top quality, 100% satisfied customers.
For more than 60 years, J. Schmid Apparatebau AG has been producing high-quality door closers under the TJSS brand name. Founded in 1944 in Suhr by Jakob Schmid, the company quickly became one of the leading suppliers in the Swiss and European markets. In the 1960s, TJSS performed pioneering work with the introduction of electric door opening systems.
Over the years, the product range was continuously expanded – from the TVV milled entirely from an aluminium flan to the slide rail door closer T46 through to various special models for specific applications (fire protection, barrier freedom, round arc or double-leaf doors, etc.).
After a change of owner in early 2008, J. Schmid Apparatebau AG is today managed in the third generation by descendants of Jakob Schmid.
