Technical Specifications / Parameters Parameter Specification Manufacturer Order Code 2TAZ220401R2104 Product Family ABB Push Button & Indicator Light System (CP-S Series or similar) Device Type Selector Switch Head (Operator) with Integrated LED Indicator Operator Style Flush-Mounted, Knurled Knob (for finger-tip operation) Knob Color Black Indicator Type Built-in, Fixed LED Indicator Color Red Number of Positions Typically 2-position (ON-OFF) or 3-position (e.g., I-0-II) selector, depending on the compatible contact block used. Operation Maintained position (stays in the selected position). Mounting Hole Diameter 22.5 mm (Standard) Contact Configuration None (This is the operator only. It requires a separate, compatible selector switch contact block which provides the actual electrical contacts, e.g., 1NO/1NC, 2NO/2NC, etc.). LED Supply Voltage Designed for a specific voltage range (e.g., 24V AC/DC, 48V AC/DC, 110V AC, 230V AC). Mechanical Life > 1,000,000 cycles Front Panel Protection Typically IP65 (Dust-tight and protected against water jets) when properly mounted with seal. Material (Front) High-impact thermoplastic (e.g., Polyamide for knob, Polycarbonate for lens). Compatibility Mounts onto standard ABB 22.5mm selector switch contact blocks. The contact block determines the switching logic and the electrical rating. Installation Snap-fit mounting from the front of the panel into a 22.5mm cutout. Electrical connections for the LED are made to terminals on the rear of the contact block.
