Overview

The Schlegel Elektrokontakt MTO (SKU: MTO) is a modular, momentary contact switch designed for industrial control applications requiring reliable circuit interruption. This switch features a single Normally Closed (NC) contact configuration with AgNi contact material, ensuring durability and resistance to wear over 1 million switching cycles under rated load. The MTO is engineered for secure screw connections, accommodating conductors from 0.5 mm² to 2.5 mm² (up to 2 x 2.5 mm²), providing stable electrical performance in demanding environments. For AC15 applications, the MTO supports a rated operating voltage (Ue) of 240 V with a rated operating current (Ie) of 3 A. In DC13 applications, it handles 250 V at 0.2 A or 24 V at 2 A, making it versatile for both AC and DC control circuits. The MTO switch is ideal for safety interlocks, signaling circuits, and machinery automation where a circuit must be broken upon activation. Its modular design allows for integration into control panels, enclosures, and automation systems requiring precise and repeatable switching operations. The screw connection (torx/slot) ensures secure wiring, reducing the risk of loose connections in high-vibration environments. With a compact footprint and robust construction, the MTO is a dependable choice for engineers and technicians prioritizing reliability and electrical safety in industrial applications.
