Description

Push-push assembly Background Push-push assemblies are used in applications where a push action can lock two components and a subsequent push action can unlock. For example, in door assemblies, a push-push mechanism is used to lock and release/open the door. Other examples of its application may be in glove boxes or overhead compartments of automobiles, where a pushing action on the lid (whether glove box lid or compartment lid) opens the lid by release of a latch, followed by a pushing action on the lid to lock the lid. In other words, push-push assemblies are used in applications that implement push-lock and push-unlock actions.
