Abstract: The invention provides a safety warning light. The safety warning light includes a light-guiding soft plastic body on which a wearing band and an electronic device placing portion are of integrated design and which is mainly composed of PU material, wherein one side of the light-guiding soft plastic body is equipped with a reflective coating, and one end or two ends of the light-guiding soft plastic body are equipped with light sources. The safety warning light can provide visibility in many ways sand many angles by using plastic with special light-guiding and light-scattering function, adding the reflective coating on bottom of a plastic armband and using high-brightness LED at two ends of the light-guiding plastic as light source. Compared with existing related like products, the safety warning light has much higher brightness and broader visibility.

Abstract: A watch has a switch mechanism 10 supported by a base 11 and a lid 13 that houses a generally conventional electric watch arrangement (not shown). The mechanism includes a semi-circular disc shaped finger tip engagable pusher 16 that can be rotated in either direction from a mean position, and also pushed radially inwards. Such movement of the pusher 16 produces radial movements of biassed plungers 23, 26 and 30 that are urged through respective apertures 24, 27 and 31 in a wall 12 of the base 11. As a result respective electrical circuits of the watch arrangement are closed to change watch functions. The mechanism 10 serves the same purpose as push buttons conventionally used in the prior art but is much easier for the user, especially if the watch is being worn on a wrist when watch functions need to be changed.
