Overview
The Schlegel Elektrokontakt CTLP_485 is a precision-engineered momentary switch designed for industrial control panels, automation systems, and machinery interfaces where reliability and tactile feedback are critical. This PCB-mount switch features a 3mm travel distance with gold-plated contacts (1.5µm), ensuring consistent electrical performance and corrosion resistance in demanding environments. Rated for 16A thermal continuous current and 3A at 240V AC15, the CTLP_485 meets EN 60947-5-1 standards for positive opening contacts (NC), providing fail-safe operation in safety-critical applications.
The integrated T55K illumination operates on 24V AC/DC with 11mA current draw, delivering clear visual feedback without excessive power consumption. With a rated insulation voltage of 300V and Protection Class II (protective insulation), this switch enhances system safety while simplifying installation via PCB-mount terminals. Its modular design allows integration with Schlegel’s MKP series contact blocks (1 NO/NC options) and lamp modules, enabling customizable configurations for emergency stops, operator interfaces, or status indication.
Ideal for automation panels, test equipment, and industrial machinery, the CTLP_485 offers a 1-million-cycle mechanical life at rated load, ensuring long-term durability. The gold-plated contacts (rated 0.4VA max at 20V) make it suitable for low-voltage signal applications, while the compact design (panel cut-out Ø16.2mm) fits standard control panel cutouts. Manufactured in Germany by Schlegel Elektrokontakt, this switch combines German engineering with compliance to international standards, making it a trusted choice for OEMs and system integrators.
