IP66 rated illuminated vandal resistant switches
May 28, 2012 // Julien Happich
All MPI switches from Bulgin have bodies and buttons machined from high-grade stainless steel. A tough Polycarbonate lens in the stainless steel actuator gives a robust and aesthetically-pleasing switch.
All switches are front-panel sealed to IP66. However, Bulgin's new range is also rear-of-panel sealed. This makes them suitable for use outdoors or in other situations where condensation or leakage behind control panels can be problematic. Rear panel sealing is available in a variety of styles, including single and dual colour with dot or ring LED illumination. Independent switch and LED terminals allows customers the flexibility to choose between permanent or controlled illumination. Contacts are single-pole push-to-make. The switches have either solder tags or screw terminals, which facilitates easy field servicing, and also feature potted moulding and flying leads to the rear of the switch. With integral supply resistors the LEDs can now be driven directly from 6, 12 and 24V supplies.
The MPI series is tested to 750,000 mechanical and 35,000 electrical operations and rated at 50mA, 24V dc. The series has also recently undergone design improvements at construction stage, incorporating surface mount LEDs and TVS’s.
All switches in the MPI series have momentary action contacts making them suitable for access control and door entry applications including lifts, panic buttons, car park barriers, emergency telephones, vending machines and food processing.
