PETERCEM

What PETERCEM does

Petercem Switches (PETERCEM) is a French manufacturer of electromechanical and inductive microswitches, position sensors, and detection solutions engineered for severe environments. Founded in 1956 and headquartered in Frontonas, France, the company develops standard, semi-custom, and fully customized switching products — including hermetically sealed microswitch ranges (G3, T3, R, H, Z3, Z3E), contactless inductive proximity sensors, hour counters, backlit push buttons, manually operated switches, and limit switches — qualified to stringent aerospace, defense, and nuclear industry standards (MIL-PRF-8805, MIL-STD, DO160, IEEE, RCCE, EN 9100, ISO 9001, ISO 19443, ATEX, CCC). Operating temperature ranges extend from -55°C to +250°C, with hermetic sealing, vibration resistance, and nuclear radiation tolerance for safety-critical functions.

The company's components are deployed across civil and military aerospace (Dassault Falcon business jets and Rafale fighters; Gulfstream G700; Bombardier Global Express; Airbus A320 family, A400M, C27J; Airbus Helicopters H125 and H160; Leonardo AW139/169/189/249; ESA's Orion spacecraft via TESAT), defense platforms (Naval Group Scorpene submarines, Nexter CAESAR/VBCI/LECLERC, MBDA SCALP), and nuclear energy (EDF-qualified K1/K2/K3 limit switches, Framatome), with secondary exposure to industrial, medical, and railway niches. Manufacturing is conducted in-house at the Chimilin site, including PCB assembly and series production, with a logistics platform in Veyrins-Thuellin and registered operations under SIRET 518 182 639 00030. Petercem Switches is a member entity of the MAFELEC TEAM diversified industrial group, alongside Mafelec, Petercem Sensors, TSL-ESCHA (Halver, Germany), Comtronic, Stopcircuit, Full Electronic System, and regional entities in China, Poland, and the UK.

Commercially, the company runs an enterprise field-sales motion with dedicated commercial and technical teams supporting customers from specification through delivery, supplemented by web-based inquiry handling and multilingual website presence in French, English, and German. Revenue is generated through one-time/perpetual license sales of standard products (tariff-based, ex-works pricing, €200 minimum invoice, one-month offer validity) and unit-priced multi-year contracts for custom-engineered equipment, with buyers potentially participating in costs for technically complex offers. In 2025 the company launched the M-SMART Interface — a SMART front-lighting and connectivity product for rail vehicles integrating predictive maintenance, automated fault detection, and remote configuration via CAN or Ethernet — representing its first explicit AI-enabled product line.
