Product overview
EK6 indoor earthing switch is equipped with a quick closing mechanism, and the closing mode of this mechanism is independent from the driving shaft of earthing switch. When closing the grounding switch, the action of the closing mechanism and the speed and torque of the operating shaft are independent of each other. On the contrary, when the grounding switch is switched off, the toggle spring will not affect the switching speed of the moving contact.
