This #7210 hand control is the most common Limoss hand control in use today.  This #7210 has a one piece cord that “disappears” down through a hole in the chair and normally plugs in underneath the chair to a short cord off the motor.  It has a round plug with a 90 degree angle that has five pins in a semi-circle.  It is very similar to the Okin #6210 standard hand control, and in fact they are interchangeable in any chair that uses this type hand control.
