Overview
The Schlegel Elektrokontakt ATL2_AU is a precision-engineered momentary switch designed for industrial control panels, automation systems, and machinery requiring reliable switching with visual feedback. This 4-pole device features 2 normally closed (NC) and 2 normally open (NO) contacts, ensuring flexible circuit control in demanding environments. The AgNi gold-plated contacts deliver superior conductivity and corrosion resistance, rated for 16A continuous current and 1 million switching cycles at rated load. Connection is simplified via 2.8 x 0.8mm Faston terminals, providing secure, vibration-resistant wiring. The integrated T55K lamp holder supports optional 24V white LED illumination (11mA operating current) for clear operational status indication. Certified to EN 60947-5-1 and EN 61058-1 standards, the ATL2_AU offers rated insulation voltage of 300V and meets protection class II requirements. Typical applications include control stations, emergency stop systems, and operator interface panels where momentary actuation and visual feedback are critical. The ATL2_AU has a switching function of momentary. It is equipped with 2 x NC and 2 x NO contacts. The contact material is AgNi gold-plated. The protection class is II, signifying protective insulation. Illumination is provided, and it utilizes a T55K lambholder.
