A heavy current reed switch contact structure comprises at least one set of elastic reed electrode (11, 12) or at least one fixed electrode (12) and an elastic reed electrode (11). The reed electrode (11, 12) is made of a conductive material. Contacts (13, 14) are arranged on opposing surfaces of mutually overlapping ends. A side of the end having the contacts is disposed with an arc discharge device (16, 162). The reed switch employs a specially designed contact structure, and the arc discharge structure device is additionally disposed on the basis of a traditional switch contact structure. As a result, the reed switch quickly transfers to the contact arc discharge structure device an instantons arc generated upon switching the switch contact, thereby easing burnout resulting from an arc on the contact surfaces of the contacts, enabling the contacts to be less prone to being adhered together, and considerably increasing a bearing current and a switching capacity of the reed switch. The heavy current reed switch contact structure has a simple structure and provides a heavy bearing current.

A transportable container assembly including a transportable container defining an enclosed interior space and having an opening member cooperatively engaging a mounting frame. The opening member has a closed position and an open position and access to the interior space is permitted in the open position. A localized device or system is attached to the transportable container and is coupled to an electrical power source. A reed switch apparatus coupled to the transportable container communicates the position of the opening member to the localized device or system. The localized device or system provides a localized function depending on the reported position of the opening member. The localized function includes at least one of a group consisting of a local lighting function, local locking mechanism action and local refrigeration system action/function. The localized device or system communicates the position of the opening member to a remote device or system at a location remote from the transportable container. The remote device or system is capable of providing remote monitoring and control functions or actions at the transportable container depending on the communicated position of the opening member.

A magnetic keyboard has a plurality of magnetic keyswitches, and each magnetic keyswitch include a base, a keycap, a supporting device, a magnetic component and a metal thin sheet. The base has at least one engaging structure and a hole. The supporting device has a first support, an end of the first support is movably connected to the engaging structure, and the other end of the first support is movably connected to the keycap. The first support has a magnet portion. The magnetic component is disposed on the base and functioned with the magnet portion to provide a recovering force to the keycap. The metal thin sheet is disposed under the base and has a bendable cantilever portion covering the hole. While the cantilever portion is bent by an external force, the magnetic component can be removed through the hole.

A relay is disclosed. In an embodiment a relay includes a magnet armature including a magnetic core and a permanent magnet secured to the magnet armature for identifying a position of the magnet armature.

A wearable absorbent hygiene article includes an electronics unit, a power source and a magnetic switch. The magnetic switch operably couples the electronics unit to the power source. The magnetic switch is configured such that the power source supplies power to the electronics unit when the magnetic switch is in an ON state and such that the power source does not supply power to the electronics unit when the magnetic switch is in an OFF state. The magnetic switch is further configured such that a movement of a magnet relative to the magnetic switch switches the magnetic switch from the OFF state to the ON state.

A liquid level control module comprising an elongated tubular housing immersible through a surface of a liquid and into a bulk volume of the liquid, and first, second, and third electrical switches, and first and second floats movable along the tubular housing. The first electrical switch is disposed within a lower portion of the tubular housing, the second electrical switch is disposed within an intermediate portion of the tubular housing, and the third electrical switch is disposed within an upper portion of the tubular housing. Each of the switches has an open state and a closed state. Motion of the first float relative to the first switch changes its state. Motion of the second float relative to the second switch changes its state, and motion of the second float relative to the third switch changes its state. Thus a two-float module may provide three level control signals.

A wearable absorbent hygiene article includes a liquid permeable top layer, a back layer, an absorbent member, an electronics unit, a power source and a switch. The liquid permeable top layer is adapted to face the wearer during use. The back layer is opposite to the top layer. The absorbent member is located between the top layer and the back layer. The switch operably couples the electronics unit to the power source. The switch is configured such that the power source supplies power to the electronics unit when the switch is in an ON state and such that the power source does not supply power to the electronics unit when the switch is in an OFF state. The power source, the switch and at least a portion of the electronics unit are disposed between the top layer and the back layer.

A washing machine is provided. The washing machine may include a main body having a laundry loading hole formed therein, a door coupled to the main body to selectively open and close the laundry loading hole, a protruding part coupled to the door and selectively received in a protrusion housing coupled to the main body, a plurality of reed sensors provided in one of the door or the main body, and a magnet provided in the other of the door or the main body, outside of the protrusion housing so as react to the magnet and sense and opening/closing of the door.

A triggering structure for an electronic lock includes a reed switch which is mounted on the lock body base and of which an ON-and-OFF state is acquired by an electronic lock control system, a permanent magnet for controlling the ON-and-OFF state of the reed switch, and a lever which passes through a handle and is mounted on the handle, ends of the lever each extending out of the surface and back face of the handle, the permanent magnet being attached to the end of the lever extending out of the back face of the handle. Also, an electronic lock and a triggering method thereof.
