A tamper resistant receptacle having shutter doors engaging a toggle mechanism wherein each shutter door must engage the toggle mechanism to move the device into the open position. When engaged properly by insertion of force into both the hot and neutral openings of the device simultaneous by the hot and neutral blades of an electrical plug, the shutter doors pivot to contact the toggle platform with force sufficient to overcome a spring bias and allow the platform to descend downwardly a distance sufficient to uncover blade openings in the platform and allow the blades to engage the device's electrical contacts. If only one of the pivoting doors contacts the platform, the platform tips, or toggles, in the direction of the door which blocks the item inserted into the receptacle opening of the device from reaching the underlying electrical contact.
