Technical Parameters Electrical Contact Blocks: Not included — must be added separately. Intended Control Voltage: Determined by the contact blocks and LED/lamp block selected. Insulation Rating: Designed to meet low‑voltage control circuit requirements. LED Voltage: Depends on the LED/lamp module used (sold separately). Mechanical / Environmental Function Mode: Maintained — pushbutton remains engaged until manually toggled. Mechanical Life: High cycle life suitable for frequent operation. Operating Temperature Range: Approximately –25 °C to +70 °C. Storage Temperature Range: Approximately –40 °C to +85 °C. Protection Rating (Front): High ingress protection (front panel) for dust and water resistance. Protection at Terminals: Basic terminal protection when properly mounted in enclosure. Physical Dimensions Width: ~29 mm Height: ~29 mm Depth: ~33 mm Weight: ~0.012 kg Panel Cut‑out: Standard 22 mm diameter hole. Typical Applications Human‑machine interfaces (HMIs) for industrial automation. Control panel operator stations requiring a maintained push input with visual indication. PLC or relay control circuits where illuminated status feedback is needed. Any application requiring reliable, modular pushbutton operation with flexible contact configurations.
