An automotive combination switch having a simple relay connector structure between switch units, comprising a smaller number of parts and excelling in assemblability and reliability. The structure comprises: a light control switch unit (1) comprising a case having a crosspiece fitted into a groove (5a) in a body (5), an elastic fitting tab (7a), and a stopper claw (8a) disposed thereabove, a plurality of functional switches housed in the case, and a fixed connector (10a) disposed in the bottom part of the case and adapted to take out switching signals; and a wiper control switch unit (2) housing a plurality of functional switches and similarly having a crosspiece, a fitting tab (7b), a stopper claw (8b) disposed thereabove, and a fixed connector (10b) housed in the unit (2). When the switch units are fitted to the body (5), a relay lead (17) having at both ends movable connectors (19a, 19b), detachably fitted to the fixed connectors (10a, 10b) of the switch units is movably engaged with the body (5).

An input device includes a button, a case operable to guide the button for allowing the button to slide, a switch fixed to the case and activated with the button, a motor fixed to the case, a driving member fixed to one of the button and the motor, a coil spring fixed to other of the button and the motor. The coil spring is operable to be engaged with the driving member. The coil spring is operable to be rotated to move relatively to the driving member. Since the button is linked to the motor with the coil spring, the button moves in up and down directions, and the input device has a simple mechanism operable to activate the switch.

A switch device is arranged such that the intermediate portion of a shape memory alloy wire (17) is held by a drive body (9) connected to one end of a link mechanism (4), and the opposite ends of the shape memory alloy wire (17) are fixedly held by a printed board (13). The opposite ends of the shape memory alloy wire (17) are fixed on the printed board (13), and the shape memory alloy wire (17) is heated by power supplied from a circuit, so that it is deformed by shape memory effect, thereby actuating the drive body (9). At that time, since the electric connection is fixed, there is no possibility of damage due to fatigue even when repetitive operations are frequently performed, thus improving reliability. Further, separate parts such as electric wires become unnecessary, contributing to simplicity, and the process for attaching electric wires also becomes unnecessary, making it possible to provide an inexpensive switch device.

摘要:
The present invention offers a switching device in which the intermediate part of shape-memory-alloy wire (17) is retained by actuator (9) connected to one end of link mechanism (4), and both ends of shape-memory-alloy wire (17) are fixedly retained by printed-circuit board (13). Both end parts of shape-memory-alloy wire (17) are fixed on printed-circuit board (13). This shape-memory-alloy wire (17) generates heat due to electric power supplied from the circuit, generates the shape-memory effect to deform. This causes actuator (9) to operate. On this occasion, because the electrically connected part is fixed, even for frequent repetitive operations, damage due to fatigue does not occur, thus improving reliability. In addition, the device can be simplified because it dispenses with a separate part such as a current-carrying wire, and not requiring a process such as an installation work for current-carrying wires offers low-cost switching devices.

摘要:
A torque detector capable of detecting an amount of torque, rotation angle and rotational speed with high resolution. First rotor and second rotor are retained individually in bearings, and they each have a gear on periphery thereof. First magnet and second magnet have pairs of magnetic poles, and disposed to ends of the first rotor and the second rotor respectively. First and second magneto-sensitive elements for detecting magnetic fields produced by the first and the second magnets are placed along an axial direction of the first and the second rotors in a manner to face the first and the second magnets respectively with a predetermined space. An input shaft and an output shaft are in engagement to the first and the second rotors respectively with gears, and the output shaft is connected to the input shaft. The torque detector obtains an amount of relative rotational displacement between the input shaft and the output shaft based on signals output by the first and the second magneto-sensitive elements.
