DC switching presents specific challenges, including the formation of electrical arcs that can damage contacts, generate EMC interference, and compromise safety. Therefore, designers seek solutions that minimize these risks, offer a long service life, and are suitable for compact and demanding environments.
SCHURTER introduces its new EDC Switch (Electronic Direct Current), designed to provide reliable DC switching even in the most demanding environments. This switch combines the mechanical precision of a microswitch with integrated power electronics, achieving completely arc-free switching and thus eliminating one of the biggest risks of DC switching.

Key Features:
The new Schurter EDC Switch incorporates an intelligent architecture that detects the start of a disconnection and cuts off the current in a controlled manner before any electrical arc occurs. This protects both the system and the surrounding environment, preventing damage to the contacts and potential electromagnetic interference.
• Complete arc protection: Thanks to its integrated electronics, the contacts do not erode, eliminating the risk of sparks.
• Long service life: Withstands more than one million switching cycles, reducing maintenance and replacement costs.
• Compact design: Its small size allows for integration into limited spaces, ideal for embedded systems or control panels with space constraints.
• Rated current: 10 A at 48 VDC, suitable for medium-power DC applications.
• Reliability and efficiency: Ideal for DC systems powered by batteries or backup power.
Two versions available:
EDC 01: Designed for the Schurter MSM II circuit breaker.
EDC 02: Standalone version compatible with universal actuators.

The result is a robust, reliable, and easy-to-integrate switch that combines the best of traditional mechanics with the advantages of modern electronics.

Applications:
Thanks to its safety, reliability, and compact design, the EDC Switch is suitable for multiple sectors and applications:
• Electric mobility: electric vehicles, scooters, and DC charging stations, where safety and efficiency are key.
• Aerospace: power distribution in aircraft, drones, and onboard systems, where space and reliability are critical.
• Industrial robotics: control of motors and actuators in mobile robots and automated systems.
• Industrial control: control panels, automation machines, and battery-powered DC systems, where robustness and component lifespan are essential.
