Overview

The Schlegel Elektrokontakt CTF (SKU: CTF) is a precision-engineered momentary action switch designed for industrial control applications requiring reliable electrical switching. This switch features a 3 mm travel distance with a mechanical lifetime of 1,000,000 switching cycles, ensuring long-term durability under rated load. The CTF is equipped with 2.8 x 0.8 mm Faston terminals for secure and efficient electrical connections, compatible with standard Faston connectors and fully insulated or partially insulated Faston receptacles. The internal contact configuration includes 1 inverter (NC/NO) setup, providing versatile switching capabilities for control circuits. Contacts are gold-plated to a thickness of 1.5 µm, delivering superior conductivity and corrosion resistance—critical for maintaining signal integrity in low-voltage or infrequently actuated applications. The switch meets Protection Class II standards for enhanced safety, featuring double or reinforced insulation to protect against electrical hazards. For AC15 applications, the rated operating voltage (Ue) is 240 V with a rated operating current (Ie) of 3 A. For DC13 applications, the switch supports 250 V at 0.2 A or 24 V at 2 A. The minimum operating voltage is 5 V, and the minimum current is 1 mA under laboratory conditions, making it suitable for sensitive control signals. The CTF switch is designed for integration into control panels, machinery, and industrial equipment where momentary actuation is required. Its compact plastic construction and IP00 front protection rating indicate it is intended for use within enclosures or panels that provide environmental protection. The switch operates in any mounting position and features a torque range of 1.5 Nm to 1.9 Nm for secure mounting.
