About Leitronic
Since 1969, Leitronic AG has been developing and producing industrial electronics with a focus on elevator emergency call systems and special telephony devices. On behalf of customers, the company also manufactures and develops electronic products for other industries. The entire value chain – from SMD assembly of the PCB to assembly of the finished device – takes place in its own production facility in Zufikon in the canton of Aargau; all devices are 100% tested before delivery. The portfolio includes elevator emergency call systems per EN81-28, firefighter solutions per EN81-72, ATEX solutions for Ex zones, lone-worker protection devices, baby monitoring, and the Leitronic Portal for routine call monitoring, remote configuration and SIM card management. Reference customers include CERN, SBB, ETH Zurich, BASF, Novartis, Roche as well as the elevator manufacturers Otis, Schindler and KONE.
