Abstract

A latch suitable for use on the door of a walk-in refrigerator can be opened from the exterior thereof and in addition from the inside of the cabinet as well as by means of an electrical signal. The latch is provided with a vapor barrier to prevent flow of water vapor along that part of the mechanism by means of which the latch is operable from the interior of the cabinet, flow of water vapor presenting the danger of frost-formation in said mechanism which could adversely affect the operation thereof. Optionally, the latch is provided with a switch which is closed on operation of the latch to activate an external device such as a vent port or an alarm signal.
