Overview
The Schlegel Elektrokontakt DTO momentary switch (SKU: DTO) offers robust performance for industrial control applications. Featuring a single normally closed (NC) contact configuration, this switch is built with durable AgNi (Silver Nickel) contact material, ensuring reliable operation and longevity. The momentary action provides a precise 6 mm travel, ideal for signaling and control functions where immediate response is critical. Installation is streamlined with its Cage-Clamp connection type, accommodating wire sizes from 0.08 mm² to 2.5 mm² (AWG 26-14), and offering push-in connection capabilities for up to two wires per connection side. This design simplifies wiring and maintenance, reducing downtime. The DTO switch adheres to Protection Class II standards, providing essential protective insulation for enhanced safety in electrical installations. It is designed for panel mounting with a standard Ø 22.3 mm cut-out and a front bezel diameter of Ø 28 mm, with a front bezel height of 2 mm. The travel distance for the panel mount version is 2.3 mm/1.8 mm. Rated for AC15 at 240V with 3A and DC13 at 250V with 0.2A (or 24V with 2A), it boasts a thermal continuous current (Ith) of 16A and a rated insulation voltage (Ui) of 300V. The contact blocks, such as the MKPTO, utilize push-in connections and AgNi material, supporting a lifetime of 1 million switching cycles at rated load. Manufactured in Germany (DE), the Schlegel Elektrokontakt DTO is a dependable choice for control panels, machinery automation, and safety interlock systems where precise switching and electrical safety are paramount. Its compatibility with SHORTRON® connect systems further enhances its integration capabilities.
