Overview
The Schlegel Elektrokontakt MTOSFE (SKU: MTOSFE) is a precision-engineered momentary switch designed for industrial control panels, machinery, and automation systems. This modular switch features a 6mm travel distance for reliable actuation, ensuring consistent performance in demanding environments. The switch is equipped with 2x 2.5mm² screw connection terminals, providing secure wiring for currents up to 16A (thermal continuous current) and voltages up to 600V (rated insulation voltage). The AgNi (silver-nickel) contact material delivers excellent conductivity and longevity, with a rated operating current of 3A (AC15, 240V) and 2A (DC13, 24V). The MTOSFE includes one normally closed (NC) and one normally open (NO) contact configuration, complying with EN 60947-5-1 standards for positive opening contacts. With a protection class II rating (IP20), this switch offers protective insulation for enhanced safety in industrial applications. The switch is manufactured in Germany by Schlegel Elektrokontakt, a trusted name in industrial electrical components. Ideal for use in control panels, machinery interfaces, and automation systems, the MTOSFE ensures reliable switching performance with a lifetime of 1 million switching cycles at rated load.
