ABSTRACT:
EMI (electromagnetic interference) is prevented by grounding the switch operator. This is done by placing an electrically conductive spring brush within the switch housing to connect the toggle lever to the metal frame of the switch. Since the metal frame is connected through its mounting panel to ground, the toggle lever becomes grounded to prevent EMI.
