WINDSOR --  Multi-Contact USA, a Sonoma County maker of electrical and electronic connectors, has leased the former Windsor Vineyards building on the Town Green and intends to showcase its products there.

The lease on the 42,500-square-foot building is one of the largest Sonoma County commercial real estate deals this year.

According to Multi-Contact’s Connectors Division Manager Ian Pratt, the building will be used as a national training center as well as a showroom for the company’s total product line, which includes solar components.

Multi-Contact, a subsidiary of a Swiss electric and electronics firm, is currently headquartered a couple of miles south on Skylane Boulevard near the Charles M. Schulz-Sonoma County Airport. The company has 10 regional sales offices across the U.S. Its precision connectors and interconnecting systems are used in the aerospace, robotics, medical, industrial manufacturing and test and measurement industries in addition to the solar industry.

“This is a tenant committed to ecological sustainability," said Craig Delles, president of Ham Delles Co. Inc., which has been marketing the property for owner Richard Mendelsohn of San Francisco. “Multi-Contact will be adaptively reusing virtually all of the existing tenant improvements, installing a solar system and possibly an electric vehicle charging station.”

The building on the former Bell Road, now 100 Market St., has been vacant since Windsor Vineyards moved its personalized wine label marketing operation near the airport in January.
