A low profile fixture button is provided for adhesive attachment to a substrate in a temporary or substantially permanent manner. The fixture button includes a plurality of preferably four over-center spokes substantially in a common plane and carrying a mounting plate having a pressure sensitive adhesive material thereon. The spokes are carried by an outer backstop rim, and are initially oriented with the mounting plate advanced toward the substrate. In a preferred form, the backstop rim seats within a counterbore formed in the rear side of a larger attachment adapted for low profile mounting onto the substrate. Pressing of the fixture button toward the substrate engages the advanced mounting plate with adhesive thereon with the substrate, and forces the spokes to displace over-center to a retracted position withdrawn substantially into the backstop rim and any associated larger attachment for low profile mounting onto the substrate.
