Tamper Resistant Mechanism For 15 and 20 Amp Electrical Receptacles

摘要

A tamper resistant shutter assembly for an electrical device includes a housing. A first shutter member is movably disposed in the housing between closed and open positions. A second shutter member is movably disposed in the housing between closed and open positions. A third shutter member is movably disposed in the housing between closed and open positions. The third shutter member is movable from the closed position to the open position by movement of the second shutter member from the closed position to the open position. A fourth shutter member is movably disposed in the housing between closed and open positions. The fourth shutter member is movable from the closed position to the open position by movement of the first shutter member from the closed position to the open position. A fifth shutter member is movably disposed in the housing between closed and open positions. The fifth shutter member is prevented from moving from the closed position to the open position when the fourth shutter member is in the closed position.
