The 61-8490.22 is a snap-action switching element designed for low-voltage switching applications in human-machine interfaces. It features a self-cleaning, double-break snap-action switching system with 1 normally closed (NC) and 2 normally open (NO) contacts, rated for 150 V AC/DC @ 5 A with a switching rating of 125 VAC at 2.5 A (AC-15 service category) or 250 VDC at 0.15 A (DC-13 service category). The switching element operates over a temperature range of -25°C to +55°C, with an electrical lifetime of =50,000 cycles at 250 VAC and 2 A, and features a rated impulse withstand voltage of 4 kV and rated insulation voltage of 320 VAC. It employs gold-plated silver contacts with a plug-in terminal (2.8 × 0.5 mm) and is compliant with EN IEC 61058-1 and EN IEC 60947-5-1 standards. This switching element is ideal for industrial control panels, appliances, and safety-critical applications requiring reliable contact switching and high dielectric strength.
