摘要： The present invention provides a relay with a shape memory alloy (SMA) wire driven mechanism. Conventional mechanical relays rely on electromagnetic principle to operate. Hence, magnetic fields of electromagnetic relays often interfere with magnetic fields of other electrical components, thus resulting in the components physically interfering with each other. The present invention utilizes the shape memory characteristics of a SMA wire to achieve the purpose of changing the operation of the relay. Specifically, when a SMA wire is heated, it restores to its original shape or original length. Comparing to conventional mechanical relays, the relay provided by the present invention does not magnetically interfere with other electrical components, and thus is able to function effectively. In addition, because the relay of the present invention does not require iron cores or coils, available space therein is increased and may be used to accommodate control circuits with various functions.

摘要： Provided is a reusable fuse having an over-current prevention function. When an over-current that is greater than a reference level is supplied to the reusable fuse and temperature of a positive temperature coefficient thermistor is higher than a specific critical temperature, then an electric resistance of the positive temperature coefficient thermistor increases, a main spring is extended, and thus the spindle is moved toward a side of a housing due to a tensile strength of the main spring and is electrically disconnected from a first lead terminal, thereby continuously blocking flow of current between a second lead terminal and the first lead terminal. When the over-current subsides, then the positive temperature coefficient thermistor is cooled, the tensile strength of the main spring decreases, and thus the spindle is moved toward another side of the housing to be electrically connected to the first lead terminal, thereby allowing the reusable fuse to return to a normal operation state.
摘要翻译：提供具有过电流防止功能的可重复使用的熔断器。当大于参考电平的过电流被提供给可重复使用的熔断器时，正温度系数热敏电阻的温度高于特定临界温度，则正温度系数热敏电阻的电阻增加，主弹簧延伸，因此主轴由于主弹簧的拉伸强度而向壳体的一侧移动，并且与第一引线端子电断开，从而连续阻止第二引线端子与第一引线端子之间的电流流动。当过电流消失时，正温度系数热敏电阻被冷却，主弹簧的拉伸强度降低，因此主轴向壳体的另一侧移动以电连接到第一引线端子，从而允许可重复使用的保险丝恢复正常运行状态。

摘要： A device, such as a switch structure, is provided. The switch structure can include a contact and a conductive element each respectively disposed on a substrate. The conductive element can be composed substantially of metallic material, and can be configured to be deformable between a first position, in which the conductive element is separated from the contact by a separation distance, and a second position, in which the conductive element contacts the contact and stores mechanical energy. The conductive element can be further configured such that, subsequent to being deformed into the second position at a temperature between about room temperature and about half of a melting temperature of the metallic material for a cumulative time of at least 107 seconds, the separation distance in the absence of external forces varies by less than 20 percent over the cumulative time.

摘要： At the time of start of usage, a voltage to be applied to a shape memory alloy wire 102 by a feedback control circuit 120 is set to a first voltage value (step S1), and at a limit resistance value detection step, (the feedback control circuit) measures a limit resistance value when the shape memory alloy wire 102 can be contracted (step S2), and upon storing the limit resistance value, a value of the maximum voltage to be input by the feedback control circuit 120 is set to a second voltage value (step S3). At an input electric power optimization step, a target resistance value is indicated, and the feedback control is carried out such that the resistance value indicated is not lower than the limit resistance value (step S4). Thereafter, voltage is stopped at the time of stopping the use of the actuator.

摘要： A thermally activated electrical interrupt device incorporates a thermally activated portion (110) engaging with an electrical interrupt portion (120). The thermally activated material (114) expands when heated, causing an interrupt control rod (140, 180) to open an electrical contact (123, 125, 126/132, 134). When the interrupt device is placed into an interrupt state, a reset mechanism maintains the interrupt control rod (140) in the interrupt state until specifically reset.

摘要： The thermal circuit breaker and switch has fixed and movable contacts, and non-conductive contact and trip actuators. The movable contact is provided on the free end of a lever arm that normally biases the movable contact toward its open position. The contact actuator transfers movement from a rocker or operator to the movable contact arm when no overload condition exists. The trip actuator is L shaped and rotates in a socket when engaged by a thermally sensitive bi-metallic element so as to allow one end of the contact actuator to float freely, allowing the movable contact arm's bias to open the circuit. The bi-metallic element is so positioned as to engage and rotate the trip actuator only when the bi-metallic element is deformed due to an overheat condition that occurs with an overcurrent. A compression spring acts between the upstanding legs of the trip actuator and the underside of the rocker thus biasing the rocker to the `off` position and biasing the trip actuator to the `reset` position. The rocker employs hooks or posts to engage and position the contact actuator to the reset position after being tripped or manually switched off.
