Abstract: A push-push latch includes a slider slidably disposed on a frame. A resilient element is to urge the slider toward an extended state. The slider or the frame defines a cam-track. A pin member is connected to the frame or the slider. The pin member selectably engages a closed course in the cam-track to cause the slider to alternate between a retracted state and the extended state in response to alternating application and removal of an actuating force on the slider. An interference member is on the frame to selectively prevent the pin member from engaging the closed course thereby locking the slider in the retracted state. A pivotable catch is rotatably on the slider to open in the extended state and to close in the retracted state. A shape memory alloy actuator selectively causes the interference member to selectively prevent the pin member from engaging the closed course.
