Physical
Illumination | Incandescent – 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). |
---|---|
Seals | Internal sealed version (standard). Optional external gasket panel seal (VPS). |
Base | Polyester 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
Environmental | Sealed 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. |

Dust | Per Mil-Std 810C, Method 510.2 Air Velocity 300 ±200 Feet/Min, Test Duration 16 Hrs. |
Thermal Shock | Per Mil-Std 202F, Method 107F, Test Condition A, -55C to 85C. Test criteria – pre and post test contact resistance. |
Moisture Resistance | Per Mil-Std 202F, Method 106F, Test Criteria – pre and post test contact resistance. |
Ignition Protection | All Contura switches with sealed construction (standard) meet the requirements of UL1500/ISO8846 for ignition protection, in addition to compliance with EC directive 94/25/EC for marine products. |
These V-Series Contura III rocker switches, developed alongside the Contura II version in the early 90’s, have become the choice of the transport market, particularly the marine sector, ever since. This innovative product features snap-in panel mounting, an interchangeable actuator, quick-connect terminals with barriers and are available in single or double pole with or without indicators.
