Abstract: A heart cam mechanism of a switch includes a cam groove, which includes a heart cam and surrounding cams, and a lock pin. The heart cam has a concave part, a first vertex opposite the concave part, and second and third vertices on a concave-part side. While the switch is in a locked state, an upper end part of the lock pin is engaged with the concave part of the heart cam, and is positioned at a locking position. While the switch is pressed, the upper end part slides while pushing against a bottom surface of the cam groove located outside the heart cam, and moves along a heart-shaped path, which is depressed at the locking position. This configuration prevents an end part of the lock pin from moving in a reverse direction even when a step-like part of the bottom surface of the cam groove is worn out.

Abstract: This invention provides a switch including a housing, a plunger that slides in a press direction or a return direction with respect to the housing, a return spring that biases the plunger in the return direction and is compressed by a slide of the plunger in the press direction, a plurality of terminals that are brought into a conductive state according to a predetermined position of the plunger, and a terminal contact spring that makes contact with the terminals so as to bring the terminals into a conductive state by the slide of the plunger in the press direction. The terminal contact spring is disposed so as to be compressed according to the slide of the plunger in the press direction under a contact state of making contact with the terminals.

Abstract: An object of the present invention is to provide: a thermoplastic elastomer composition, which is accompanied by less environmental burden, and which has flexibility, rubber elasticity, formability and recyclability; and a molded product obtained using the same. The present invention is directed to a thermoplastic elastomer composition comprising a thermoplastic resin (A) derived from a non-petroleum source, and at least one rubber (B) selected from a natural rubber, a diene polymer rubber, an olefin polymer rubber, an acrylic rubber and a silicone rubber, the thermoplastic elastomer composition being obtained by allowing the rubber (B) to be dynamically crosslinked with a crosslinking agent (C) in the presence of the thermoplastic resin (A). Preferred (A) is a polylactic acid, or a poly(3-hydroxybutyrate), and preferred (B) is a natural rubber.

Abstract: The present invention herein provides antimicrobial zeolite which hardly causes any color change with the elapse of time even when it is incorporated into a resin to form an antimicrobial resin composition. The present invention thus relates to antimicrobial zeolite which comprises zeolite whose ion-exchangeable ions are partially or wholly replaced with hydrogen ions and silver ions; and an antimicrobial resin composition which comprises the foregoing antimicrobial zeolite in an amount ranging from 0.05 to 80% by mass.
