A data input and/or operator control system, particularly a keypad, also a POS keypad, having a lower portion and an upper portion and also at least one printed circuit board and at least one retaining plate. Inside, one or more protective mat(s) made of an elastic material is/are preferably adhesively bonded to the printed circuit board. In this protective mat, the components of the printed circuit board are recessed to as small an extent as possible and air ducts are incorporated in order to ensure that the keys are ventilated in relation to one another.

A switch seat body assembling structure includes a main body for assembling with a switch component. The main body is composed of a metal head section in the form of a thin sheet structure and a nonmetal belly section. The main body is defined with an eccentric axis and has a shaft hole positioned on the eccentric axis. The metal head section has a first wall normal to or inclined from the eccentric axis and a second wall connected with the first wall and parallel to or inclined from the eccentric axis. The first and second walls together define a space. The nonmetal belly section fills the space to connect with entire sections of the first and second walls as an integrated body. The switch seat body assembling structure improves the problems that the processing and manufacturing processes are time-consuming and troublesome and the material cost is higher.

A key structure includes a keycap and a connecting member. The keycap has a bottom surface and includes a fixing portion and an elastic arm. The fixing portion is disposed on the bottom surface, and the fixing portion has a connection hole and a first opening communicating with each other. At least one end of the elastic arm connects to a side surface of the fixing portion, and the elastic arm is adjacent to the first opening. The elastic arm has an open end communicating with the opening and a limiting surface toward the bottom surface. The connecting member includes a connection pin, one end of which connects to the connection hole and the other end of which has an extension portion. The connection pin is disposed in the connection hole, and the extension portion is disposed between the bottom surface and the limiting surface.

Mechanical keypads are disclosed. According to one embodiment, a mechanical keypad may include a key cap comprising a post extending from a bottom surface thereof; a structural element comprising a passage configured to receive the post therethrough; and a key securing device that securely receives, through the passage, the post in a recess or opening formed therein, and comprising a key switch interface on a lower surface thereof. The key cap and the key securing device may move substantially in unison when the key post is securely received in the key securing device.

A cable lock (10), including: a cable (16), for locking an object (26) thereby; a first, being the internal peripheral electric conductor (54B), surrounding the cable (16); a peripheral insulating layer (22), surrounding the first peripheral electric conductor (54B); a second, being the external peripheral electric conductor (54A), surrounding the peripheral insulating layer (22); and an electrical circuit (62), for alerting (56) once any region (58A) of the second peripheral electric conductor (54A) electrically contacts an adjacent region (14A) of the first peripheral electric conductor (54B), by crossing the peripheral insulating layer (22), thereby a blade (28) pressing on the second peripheral electric conductor (54A) induces the electrical contact of the second peripheral electric conductor (54A) with the first peripheral electric conductor (54B), thereby the electrical circuit (62) alerts (56) prior to cutting the cable (16).
