1. An actuator-controlled electric strike for operating in conjunction with a latch of a lockset, wherein the latch has an engaged position so as to secure a door in a closed state and a released position, the strike comprising:
a) a housing defining an entry chamber therein;
b) a keeper disposed in said entry chamber, wherein said keeper is movable between a locked position and an unlocked position;
c) a keeper support bracket movable between a first position and a second position, wherein when said keeper support bracket is in said first position, said keeper is in one of said locked position or said unlocked position, and wherein when said keeper support bracket is in said second position said keeper is in the other of said locked position or said unlocked position;
d) an actuating mechanism operatively connected to said keeper support bracket, wherein said actuating mechanism is actionable in a first direction to move said keeper support bracket toward said first position, and wherein said actuating mechanism is configured to allow said keeper support bracket to move in a second direction toward said second position, wherein said second direction is different than said first direction; and
e) a biasing member applying a net force to said keeper support bracket, said biasing member comprising a first biasing mechanism and a second biasing mechanism, wherein said first biasing mechanism has at least one biasing characteristic value different from that of the said second biasing mechanism, wherein said first biasing mechanism applies a first force to said keeper support bracket in said first direction, wherein said second biasing mechanism applies a second force to said keeper support bracket in said second direction, and wherein when said keeper support bracket is in said first position, said net force of said biasing member is approximately zero.
