DESCRIPTION

The FB1W-XW1E-LV422MR is an illuminated 40mm mushroom emergency stop switch designed for industrial safety control applications. It features 2 normally open (NO) monitor contacts and 2 normally closed (NC) main contacts with a push-to-lock (32N) and turn-to-reset (0.27N-m) operator mechanism. The switch incorporates a 24V AC/DC ±10% LED indicator drawing 15mA, with gold-plated silver contacts rated at 50mO maximum initial contact resistance and 100MO minimum insulation resistance (500V DC). Operating specifications include a temperature range of -25°C to +55°C (no freezing), 45–85% RH humidity tolerance, and direct opening action requiring 80N minimum force with 4mm operator stroke. The switch is rated for 100,000 electrical operations minimum (250,000 at 24V AC/DC, 100mA) and 250,000 mechanical operations, with M3.0 screw terminals (16 AWG max wire size) and IP65 operator protection. This emergency stop device is ideal for machinery control panels, production line safety systems, and automated equipment requiring reliable emergency shutdown with visual feedback.
