THEBEN — German Precision, Globally Trusted

THEBEN is not a newcomer. Founded in 1921 in Haigerloch, Germany, this engineering house has spent over a century building the invisible systems that make buildings smarter, safer, and more efficient. Their time switches and automation controls are found in Europe's most demanding commercial and residential projects — and now, through PT Klik Hiro Optima, as Indonesia's official distributor.

"THEBEN doesn't just control time. It controls the rhythm of a building;
when lights rise, when systems breathe, when energy rests."
