The classic that never misses a beat

Simple to set. Impossible to fool. The SUL 181 d is THEBEN’s benchmark analogue time switch — a quartz-controlled daily programmer built for one purpose: switching your electrical circuits on and off at exactly the right time, every single day, without fail.

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.
