Microminiature Switch for SMT Applications
SMT Switch TCS43
The TCS43 is a microminiature SMT tactile switch designed for high-performance applications requiring compact size, reliability, and precise haptic Feedback. With a footprint of just 4.2 × 3.2 mm and a low profile of 2.5 mm, it enables space-efficient PCB layouts without compromising usability.
The switch offers three actuation force options (180 gf, 250 gf, 400 gf; equivalent to 1.76 N to 3.92 N), allowing engineers to fine-tune the user experience depending on application requirements. Its mechanical lifetime of up to 100,000 cycles ensures long-term reliability, even in demanding environments.
Electrical performance supports low-power designs (10 µA to 50 mA, 1–12 VDC), while contact resistance remains ≤100 mΩ for stable signal integrity. The device operates reliably across a wide temperature range (-40 °C to +90 °C), making it suitable for both consumer and medical applications.
Typical use cases include user interfaces such as on/off switching, menu navigation, and parameter selection in high-end consumer electronics, home automation systems, IoT devices, and medical equipment (e.g., blood pressure monitors, ventilators).
The TCS43 combines compact design, robust performance, and flexible actuation characteristics
making it an ideal choice for next-generation interface solutions.

SMT Half Pitch DIP Switches for Space-Critical Applications
SMT Half Pitch DIP Switch
DTCD, DTCJ
The DTCD and DTCJ 1.27 mm pitch DIP switches are ultra-miniature SMD components designed for high-density electronic applications. With a low profile height of just 2.2 mm and up to 46% PCB space savings compared to traditional 2.54 mm solutions, they enable significant footprint reduction without compromising functionality.
Available in Gullwing and J-bend terminations, both versions are optimized for automated SMT assembly, reducing manufacturing complexity and cost. The switches support up to 1000 mechanical cycles and operate reliably across a temperature range of -40 °C to +85 °C. Low contact resistance (≤100 mΩ initial) and stable electrical ratings (up to 100 mA @ 50 V) ensure consistent signal performance.
Typical applications include address setting and configuration in industrial controls, communication systems (e.g., RS485/Modbus), server hardware (BIOS/CMOS), consumer appliances, and medical devices. Combining miniaturization, durability, and cost efficiency, DTCD/DTCJ provide a scalable solution for modern compact electronic designs.

MSM II-Switch with M12 Connector
With the new switch from the MSM II family with M12 connector (8 pins), Schurter is focusing on a solution that has been specially developed for demanding industrial and commercial applications. Thanks to the M12 connector system, robust construction, and integrated RGB illumination, this switch combines maximum reliability, functionality, and modern design in a compact unit.
The standardized M12 connector ensures fast, secure, and error-free installation—without any complicated wiring. Thanks to the fixed pin assignment, wiring errors are effectively avoided, which not only simplifies installation but also speeds it up considerably.
The mechanical design is made for permanent industrial use—shockproof, vibration-resistant, and resistant to tough environments. This means the switch will keep working reliably for years, even in extreme conditions.
The three-color RGB illumination provides clear status indication or individual signals. Example: green = active; red = off; flashing orange = error condition. This makes the switch ideal for machine controls, control systems, or user interfaces.
The new Schurter MSM II M12 switch is suitable for applications where installations must be made quickly, easily, and safely. It is used in industrial automation, machine and plant engineering, as well as in public and commercial areas where clear signaling and high reliability are required.

MSM II-Switch with common anode control of the RGB LED
The well-established MSM II mechanical switch family is growing. With the MSM II (Common Anode), Schurter is introducing a variant that uses a common anode to control the RGB LED illumination. This combines the familiar robust mechanics with visualization technology for clear feedback, easy integration, and maximum reliability in control and operating solutions.
RGB LEDs can be controlled either via a common anode (+) or a common cathode (–). While with common cathode all negative poles are connected together and the colors are controlled individually via the positive pole, the common anode variant does the opposite: all positive poles are connected, and the color channels are switched separately to ground.
The MSM II (common anode) offers maximum compatibility with modern driver ICs, PLC outputs, and microcontrollers, which are predominantly designed for common anode control. This facilitates integration thanks to a simple signal structure and reduced wiring requirements.
The combination of tactile precision, IP67 protection, robust design, and flexible RGB signaling makes the MSM II switch ideal for a wide range of applications, particularly in industrial control units such as control panels, production facilities, building automation, and access solutions.

Schurter launched an electromechanical micro switch with a switching capacity of 10A,48VDC.
EDC: Safe Switching of Direct Current
The Schurter EDC (Electronic Direct Current) switch was specifically engineered for the reliable switching of direct current in compact systems. It combines the mechanical precision of a microswitch with integrated power electronics.
The result of Schurter's new development: completely arc-free. Arcing is one of the greatest safety risks when switching direct current. The use of modern semiconductors completely eliminates arcing.
With the well-known feel of mechanical switches, the load current is switched electronically without galvanic isolation. This protects both the system and the environment from damage caused by sparking or EMC interference.
Long-Lasting and Reliable
At the same time, the EDC achieves well over a million switching cycles, as there is no arc-related erosion of the contacts. This extends the service life and reduces maintenance costs.
Ultra-Compact Design
Thanks to its compact design, the switch can also be integrated in confined installation situations. This is ideal for onboard systems in electromobility, compact power distribution systems in the aerospace industry or mobile robot solutions. The EDC also scores highly in industrial control systems with battery buffered DC supply thanks to its high level of safety, energy efficiency and ease of installation.
2 Variants
The new Schurter EDC is available in two versions. Firstly, as a stand-alone version (EDC 02) for universal actuators, and secondly as a Schurter-specific version for the MSM II switch as an actuator (EDC 01). Both versions are designed for a rated current of 10 A at 48 VDC.
Robust and Future-Proof
With the EDC switch, Schurter addresses the growing demands for safety, miniaturization and eliability in modern DC applications – a robust solution for future-proof designs.

With the MSS-IO, Schurter is entering the field of bidirectional communication via switches in industrial automation. The MSS-IO is based on the successful Schurter MSS electronic switch, which has been expanded to include an IO-Link module.
The MSS-IO switch from Schurter is based on wear-free resistance measurement and completely avoids mechanical components. Instead of capacitive technology, a precise change in electrical resistance is used for switch detection: sensitive enough to detect the smallest changes in pressure, robust enough for industrial series processes. Ultrarugged, precise and easy to integrate.
IO-Link Interface
The IO-Link interface allows bidirectional communication, parameterization during operation and real-time diagnostics. The connection is made via standard M12 connectors. Predictive maintenance and simple integration into existing Industry 4.0 environments are guaranteed.
Features
Easy to Clean
Thanks to the closed surface, the switch is insensitive to water, dirt and cleaning substances. This is a clear advantage in hygienically sensitive areas such as food processing or laboratory automation. The absence of moving parts minimizes the maintenance effort and increases the service life enormously.
