British engineering background and manufacturing traditions of Lorlin Electronics
Established in 1961 along the southern coastline of Great Britain, Lorlin Electronics represents an experienced European developer and manufacturer of electromechanical switching components.
The manufacturing facility located in Littlehampton covers more than 2000 square meters, integrating complete engineering design and volume production of rotary and keylock switches for industrial automation, measurement devices, and power distribution cubicles.
The company equipment installation features high precision injection moulding machines for forming switch housings from UL 94V-0 engineering polymers, CNC turning and stamping equipment for producing contact assemblies and spindles, as well as qualified laboratory testing benches.
Every component undergoes strict inspection of insulation resistance, dynamic junction resistance, detent torque, and operational endurance.
Engineering layout and contact assemblies of the CK rotary switch portfolio
The flagship Lorlin CK rotary switch series delivers dependable circuit configuration across low voltage control loops and instrumentation hardware.
Featuring a 30 degree indexing mechanism, the switch handles from 2 to 12 detent settings and supports switching configurations spanning from single pole up to 4 isolated poles. The switches handle working currents up to 1 A at 24 V AC or DC potentials.
Switch contact points use copper alloys finished with silver plating or gold flashing to minimize junction losses during the routing of low level electrical signals below 0.4 VA.
The product range encompasses terminals designed for manual soldering or printed circuit board assembly, alongside sealed CKF and CKS variants providing ingress protection across both the front spindle and the housing up to IP67.
Mains rotary switch assemblies of RMS series and physical isolation gaps
For dependable power disconnection and high current line routing across industrial machinery, Lorlin manufactures double pole rotary mains switches of the RMS series.
Engineered according to European electrical safety standards, the internal mechanism provides a physical air separation gap exceeding 3 mm between open power contacts, preventing flashover and arc establishment.
The switches handle continuous loads of 4 A at 250 V AC working voltages and carry formal VDE and ENEC approvals.
The switch bodies are molded from engineering polymers with elevated heat resistance, ensuring durable fire safety within electrical distribution enclosures and automated motor control cabinets.
Multi-wafer precision rotary switches of RA and PT series for instrumentation
Routing intricate multi-channel measurement lines within precision scientific apparatus requires modular stackable rotary wafer switches.
The Lorlin RA wafer switch architecture builds upon modular insulating discs equipped with dual wiping sliding contact arms that continuously wipe away surface oxide films and maintain ultra-low dynamic junction resistance throughout operation.
For compact control units and sub-racks, the PT switch family provides an optimized footprint for direct soldering into circuit boards with a standard 2.54 mm pin spacing.
The modular architecture permits combining multiple switching wafers together while maintaining positive detent feedback and an operational switching endurance exceeding 10000 complete cycles.
Binary coded and Gray coded rotary switches of BCK and GCK series
Industrial automated machinery and digital process controllers utilize discrete selector switches based on Lorlin BCK and GCK coded assemblies.
The BCK family provides a 16-position binary output format configured as true hexadecimal or inverted complementary binary representations for direct interface with digital microprocessor logic boards.
The GCK family provides Gray code switching output where only one bit shifts between adjacent detent settings, eliminating transient timing errors and false states within controller digital input buffers.
The enclosed housing construction and gold flashed contacts prevent contact oxidation and shield against factory particulate contamination.
Panel mount keylock switch families for 16 mm and 19 mm cutouts
Restricting operator access rights across machine human-machine interfaces, distribution panels, and automation enclosures relies on Lorlin keylock switches with mechanical cylinder barrels.
The product line covers standard mounting hole dimensions of 16 mm (BCL, SRL, WRL families) and 19 mm (MIS, SKL, KSR families), coupling a robust lock barrel with snap-on electrical modules.
The internal cylinder mechanisms provide options ranging from identical keys up to 50000 individual lock combinations, with key withdrawal available in single or multiple detent positions alongside spring return actuation.
The front bezel incorporates sealing rings rated up to IP67, preventing industrial fluid and moisture ingress into the control panel enclosure.
