Electronic Switching


The VM-Series is a multiplexed operator control module ideal for the Construction, Agriculture and Commercial vehicles. Rugged and sealed to IP68, the VM-Series can be used in open or closed cab environments and it connects to industry standard SAE J1939 CAN Bus protocol.

The VM-Series reduces the complexity and cost of traditional wire harnesses, increases product life and reliability, and improves assembly efficiencies.

The VM-Series was developed in conjunction with the globally successful Carling Contura® family of switches, providing the look and feel of our traditional rocker switches, but offering the benefits of a multiplexed product.
