High-Speed EMU Master Controllers: S359 CC.010, S359 CC.011, S334 & S620 Series

Holding the No. 1 market share in China's rail master controller sector, Xi'an Schaltbau engineers precision traction and braking controllers for high-speed electric multiple units (EMUs).

The S359 CC.010 single-handle master controller utilizes a 9-bit photoelectric Gray code encoder tailored for China Standard Fuxing trainsets.

For CRH380B high-speed trains, the S359 CC.011 provides an under-panel 3-handle architecture with dual optical encoders and a dedicated cam-operated direction switch.

For CRH2 trainsets, the S334CC.810 traction controller eliminates electronic boards and potentiometers entirely, relying on high-IP Schaltbau snap-action switches for maximum EMI immunity.

We supply complete master controllers, S620 CC.942 brake controllers, S324 compact controllers, replacement Gray code optical encoders, cam assemblies, and mechanical interlock components.

Metro & Urban Rail Master Controllers: S358A, S354A, S353 & S355 Series

Engineered for high-frequency urban transit duty, the S358A master controller is built to China Standard Subway specifications with a fully enclosed high-strength aluminum and stainless steel housing, PWM encoder output, and mechanical interlocking between the deadman control handle, direction

lever, and key lock.

The S354A series introduces a streamlined console profile with a rotary direction selector supporting Automatic Train Operation (ATO) and a push-pull main traction/brake handle. The round-panel S355 and rectangular S353 series utilize transverse cam stacks to minimize under-desk mounting depth.

We deliver complete subway master controllers alongside replacement PWM encoders, key locks, cam followers, and snap-action contact modules.

Mainline Electric & Diesel Locomotive Master Controllers: S357, S640 & S701

For HXD1 heavy-haul electric locomotives, the S357 master controller integrates four operating mechanisms on a single top panel: key switch, speed setting lever, Traction/0/Brake main handle (available in stepless or notched versions), and direction handle, driving precision encoders via mechanical

gearing.

The S640 series is purpose-built for standardized driver desks on SS3, SS4, SS7, and SS9 AC electric locomotives, while the S701 series equips DF5 and DF7 diesel locomotives in full compliance with GB/T 21413, GB/T 21413.1, GB/T 21413.2, and TB/T 1391-2007.

We supply complete locomotive master controllers, encoder gear trains, detent mechanisms, handles, and replacement contact elements.

High-Voltage DC & AC Power Contactors: CL, CT1000, C195 & C193 Series

Xi'an Schaltbau power contactors provide reliable arc quenching and load switching under severe railway shock and industrial environments.

The CL contactor family (rated up to 1500 V DC/AC) is available in 1-, 2-, and 3-pole configurations with double-break NO main contacts and permanent-magnet arc blowout for DC traction and auxiliary circuits.

High-capacity CT / CT1000 single- and double-pole contactors combine permanent-magnet and electromagnetic blowout to handle arduous AC and DC switching duties.

Where cabinet space is restricted, compact single-pole DC contactors C195 (up to 1200 V DC with enclosed double-break contacts) and C193 (up to 1000 V DC) deliver long electrical service life.

We supply complete contactors, replacement main contact tips, arc chutes, operating coils, and auxiliary switch blocks.

Control & Auxiliary Circuit DC Contactors: S137 & CS115 Series

The S137 and CS115 (up to 110 V DC) compact contactor families are designed for frequent remote switching of auxiliary equipment and control logic aboard locomotives, EMUs, and industrial automation panels.

Molded from high-strength insulating engineering plastics to reduce weight and enhance dielectric safety, both series incorporate an integrated coil self-induction voltage suppressor to protect electronic control units from inductive voltage spikes.

We supply S137 and CS115 contactors across all current ratings, changeover contact variants, clip-on auxiliary contact blocks, and spare coils.

Foot Switches (S298, ZL290, S293), S40X Pushbuttons & SM(N) Cam Switches

For driver vigilance (deadman) systems, Xi'an Schaltbau manufactures three foot switch families: the ergonomic S298 featuring vigilance monitoring, a self-heating treadle pad, and height adjustment; the magnetically actuated ZL290 incorporating a self-cleaning S814b snap-action switch; and the

proven S293 mechanical foot switch.

For cab control desks, the S40X pushbutton family offers modular contact blocks with flush, mushroom, or latching heads and optional anti-misoperation covers, while SM(N) universal cam changeover switches use S826/S847 snap-action contacts for reliable low-current switching.

We deliver complete foot switches, S40X pushbuttons, SM(N) cam switches, replacement contact modules, and actuator heads.

Precision Snap-Action Switches: S826 & S847 Series (IP40 / IP60 / IP67)

Xi'an Schaltbau S826 and S847 snap-action switches feature a positive double-break wiping contact system that cleans contact surfaces on every actuation, ensuring dependable conduction even at millivolt/milliamp signal levels.

The S826 series incorporates a galvanically isolated contact bridge capable of switching two independent circuits of different voltages simultaneously.

The modular S847 series is available in IP40, IP60 (dust-tight), and IP67 (waterproof per IEC 60529) enclosures for harsh door, brake, and underframe environments.

We supply S826 and S847 switches with silver alloy or gold-plated contacts for both controller maintenance and standalone industrial automation.

TJS11 Time Relays, TQG/TQM/TQW Encoders & TQD LED Signal Lamps

TJS11 integrated-circuit time-delay relays provide accurate on-delay and off-delay timing for locomotive and EMU control circuits, featuring high EMI immunity, LED status indication, and multi-group NO/NC relay contact outputs.

Xi'an Schaltbau also manufactures domestically developed TQG optical encoders, TQM PWM encoders, and TQW electronic potentiometers, alongside TQD-QL-24/S redundant LED marker/signal lamps and high-illuminance TQD-QW / TQD-BL LED headlights.

We supply TJS11 time relays, OEM replacement encoders for master controllers, and TQD external LED lighting units.

180 m² Testing Laboratory, IRIS Silver (ISO/TS 22163) & CRCC Certifications

Xi'an Schaltbau holds the ISO/TS 22163 IRIS Silver rail quality certification (audited by TÜV Rheinland), CRCC rail product certification for locomotives and EMUs, and ISO 9001, ISO 14001, ISO 45001, and ISO 50001 management certificates.

Its upgraded 180 m² in-house laboratory in Xi'an comprises a general testing zone (climatic damp-heat/cold chambers, dielectric insulation, EMC, and electrical endurance) and a dedicated contactor laboratory for making/breaking capacity, critical current, and temperature-rise testing.

Factory inspection certificates and compliance documentation are available per project requirements.
