Driver Cards

While most of our on/off function grips and joysticks contain high current switches, there are times when the switch is not capable of operating the end function correctly. We offer several different electronic modules designed to convert proportional and/or low current on/off signals into the needed format for the particular application.

Most of these modules are microcontroller based and/or programmable, which means they can be modified as required to meet our customers’ exact needs.
