A joystick assembly is disclosed. In embodiments, the joystick controls a boom and aids in insulating a user from potential electric shock. Handle utilized by the operator may be made of, or at least one surface coated or covered in, material highly-resistant to electric current. The highly-resistant material may also extend to other components such as, a connecting rod, and a mounting base. The highly-resistant components may separate the operator from electrically charged components. As well as separating the operator from potentially electrically charged components, the rod may be received at the base by force measuring sensors, or strain measuring sensors may be attached to the rod. This allows the handle and rod to be stationary and, in embodiments, rigid, and only the applied force to be measured, thus decreasing the number of components needed in the assembly.
