The bodies of these switches are machined from high grade stainless steel to produce an extremely tough yet aesthetically pleasing switch. A tough Polycarbonate lens is combined with the stainless steel button. The standard colours of red, green and amber have been joined by a blue option, and the LED housing is moulded in the same colour material as the LED's themselves. Tested to 750,000 mechanical operations and 35,000 electrically, the MPI series have single pole contacts rated at 50mA, 24V dc. The switches have either solder tags or screw terminals, useful for easy field servicing, and are front panel sealed to IP66 making them ideal for external applications. This family of switches all have momentary action contacts, which lend themselves to door entry and access control applications along with many other uses such as: car park barriers, emergency telephones, panic buttons, vending machines, lifts, prisons, petrol pumps and food processing.
