Vandal-resistant switches enable access control

This includes lifts, panic buttons, car park barriers, emergency telephones, vending machines and food processing.

All MPI switches 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, according to the company.

All switches are front-panel sealed to IP66, as well as being rear-of-panel sealed, making 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 allow customers the flexibility to choose between permanent or controlled illumination.

Contacts are single-pole push to make.

The MPI series of switches offer IP66 sealed properties, combined with a rugged design and a variety of style options.

The switches have 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 TVSs.

All switches in the MPI series have momentary action contacts
