Physical

IlluminationIncandescent – rated 10,000 hours (standard); Neon - rated 25,000 hours; LED – rated 100,000 hours 1/2 life (optional) (LED is internally ballasted for voltages to 24 VDC).
SealsInternal sealed version (standard). Optional external gasket panel seal (VPS).
BasePolyester blend rated to 125C with a UL flammability rating of 94 V-O.
Actuator - Hard Surface (standard)Basic actuator structure moulded of thermoplastic polycarbonate with a hard Nylon 66 thermoplastic surface overlay.
Actuator - Soft Surface (optional)Basic actuator structure moulded of thermoplastic polycarbonate with an elastomer overlay (Contura II and III only).

Environmental

EnvironmentalSealed version: IP68, in accordance with IEC 529, BS 5490, DIN 400 50 & NFC 20 010. This rating applies to front panel components and signifies protection against dust and the prolonged effects of immersion under pressure. The standard test for immersion under pressure requires submersion under one metre of water for 30 minutes. The V-Series switch has exceeded these parameters, having been actuated and illuminated during submersion. NOTE: Sealed switch with optional panel gasket will meet IP67 rating.
