Abstract
An actuator controlled electric strike for operating in conjunction with a latch of a lockset. The strike comprises a keeper support bracket movable between blocking and unblocking positions. When the bracket is in the blocking position a keeper is held in a locked position, and when the bracket is in the unblocking position the keeper is movable to the unlocked position. A motor is operatively connected to the bracket and is actionable in first and second directions to move the bracket between the blocking and unblocking positions. A biasing member comprises first and second springs that apply a net force to the bracket. The first spring applies a first force to the bracket in the first direction, and the second spring applies a second force to the bracket in the second direction. When the bracket is in the blocking position, the net force of the biasing member is approximately zero.
