Abstract: A mounting latch for mounting a device to a rail is provided. The mounting latch comprises: a moveable actuator having a profile; a latch mechanism comprising first and second opposed rail engaging members, at least one of the members having a face for causing the member to yield against a bias source when the latch mechanism is engaging with the rail; and a follower enabling the at least one member to follow a rotational movement of the actuator such that movement of the actuator in a first direction causes the at least one member to become unlatched from the rail.
