Maintain control of hazardous motion.  The JSHD4 acts as an emergency stop if the operator lets go of the control or grips too tightly, helping to ensure operators maintain awareness and control. Ergonomic design makes the JSHD4 easy to operate, even with gloves.

Used in applications where an operator is in the hazardous area and only limited movement of the machine is allowed.
