What ZETTLER electronics makes

ZETTLER electronics GmbH is the EMEA arm of the global ZETTLER Group, supplying electronic components to industrial and consumer electronics manufacturers across Europe. Its core product families are electromechanical and semiconductor relays, magnetics and transformers, and LCD/TFT displays, alongside switches, pushbuttons, potentiometers, encoders and thermostats. The company runs its own application-engineering function and specializes in relay development for the solar-inverter and electric-vehicle markets.

Relays are the heart of the catalog. The AZ series spans signal, power, automotive, industrial, high-power, solar and DC-power devices, plus a dedicated EV-charging line. Recent EV parts include the AZEV400, a 50-ampere, 480-volt AC four-pole power relay rated for 10 kA short-circuit endurance with a normally-closed mirror contact per EN 60947-4-1, and the AZEV140 series before it. For high-voltage DC switching the company distributes Hiitio contactors rated from 20 to 1,200 amperes and 450 to 2,500 volts DC. On the power side, ZETTLER offers PCB-mount switching power supply modules such as the APX05S (5 W SIP) and ZPO40 (40 W), high-frequency, encapsulated and toroidal transformers, DC/DC converters and chokes. Its display range runs from character modules to TFTs from 3.5 to 15 inches with resistive or capacitive touch, and its switch and control lines include detector switches and potentiometers and encoders distributed for ALPS ALPINE.

These parts serve HVAC/R, appliances and white goods, automotive and electric vehicles, telecommunications, medical, consumer electronics and renewable energy. As a components supplier rather than an original equipment manufacturer, ZETTLER sits upstream of the assemblers who buy its relays and power modules, a tier position where second-source availability and long product lifecycles matter as much as unit price.

Ownership and history

The ZETTLER name goes back to 1877, when the engineer Alois Zettler founded a workshop in Munich; he designed his first electro-mechanical relay there in 1889, and relays became the company's defining product through the twentieth century. Today ZETTLER electronics GmbH is a subsidiary of the ZETTLER Group, a vertically integrated electronics enterprise with manufacturing concentrated in Asia, including Xiamen ZETTLER in China, and operating companies in North America (American Zettler), China, Poland and Germany.

The German operating company was established in 1994 and is registered at the Munich District Court under HRB 106357. It is based at Junkersstrasse 3 in Puchheim, a suburb west of Munich, and services European markets through a distributor network spanning nineteen countries, including all major EU markets, Scandinavia, Israel and Turkey. It also operates ZETTLER Electronics Poland. Antje Jakesch, an industrial engineer who joined ZETTLER in 2003, has been Managing Director since June 2017; a 2017 company announcement named her joint managing director alongside Stefan Schlosser. The German entity is a compact sales and engineering operation; the group's scale comes from its Asian manufacturing base.

Certifications and quality

ZETTLER electronics GmbH runs a quality management system audited at regular intervals by TUV Management Service GmbH, with its current ISO 9001 certification valid until September 16, 2029. The group states that its manufacturing facilities in Asia operate automated production lines with the pertinent quality certifications, and Apollo-indexed group materials cite ISO 9001 and ISO 14001 at the group level. For buyers, the practical point is that the components carry a current, third-party-audited quality system on the sales-and-engineering side in Germany and a certified manufacturing base upstream, which is what a quality-system review of a components supplier looks for. For buyers this maps directly onto the production part approval process that automotive and industrial programs expect from a component source.

Known customers

ZETTLER does not publish named customer programs, which is normal for a components distributor whose parts are designed into third-party equipment. No OEM relationships meet the documented-or-reported evidence bar, so none are listed here.

What is on the record is the end-market focus: the company develops relays specifically for solar-inverter and EV-charging applications, and its stated served industries are HVAC/R, appliances, automotive, telecommunications, medical, consumer electronics and renewable energy. Buyers evaluating ZETTLER as a relay or power-module source should treat it as a European-facing sales and engineering channel into the wider ZETTLER Group manufacturing base rather than as a domestic manufacturer, a distinction worth confirming when nearshoring or mapping tariff exposure on imported components.
