Abstract: A switch module includes an outer shell, a button and a bracket. The button is disposed to the outer shell. The button has a base board. One side of a bottom surface of the base board is recessed in the upward direction to form an avoiding groove. A rear of the bottom surface of the base board protrudes in the downward direction to form a driving pillar. The bracket is disposed under the button. A top surface of the bracket is recessed in the downward direction to form an accommodating groove. A top surface of a bottom wall of the accommodating groove is defined as a stopping surface. The driving pillar projects beyond the stopping surface. A front end of the top surface of the bottom wall of the accommodating groove is recessed downward to form an avoiding plane.

Abstract: An input device includes a knob, a detector, an electromagnetic brake, an elastic member, and a controller. The detector detects a rotation angle of the knob. The electromagnetic brake regulates rotation of the knob. The elastic member is provided between the knob and the electromagnetic brake. When the current position of the knob in the circumferential direction is not the target position for rotation regulation of the knob, the controller does not activate the electromagnetic brake. When the current position of the knob in the circumferential direction is the target position for rotation regulation of the knob, the controller determines whether to regulate rotation of the knob based on a rotation direction of the knob, or on a rotation angle of the knob that shifts from the holding position of the knob in the circumferential direction due to deformation of the elastic member.

The pump aggregate features one such terminal box.

Abstract: In a joystick device, a rotation position detector for detecting a rotation position of a rotatable cylinder having one end coupled with a dial knob is provided between the cylinder and a case. The detector includes a drive gear provided around the cylinder, a rotary body which has a driven gear provided around its outer periphery and is in mesh with the drive gear, multiple magnets provided on the rotary body, and a magnetic sensor provided in the case to face one end portion of the rotary body to detect the rotation position of the cylinder based on positional change relative to the magnets along with rotation of the rotary body. Such arrangement enhances the degree of design freedom for arranging a magnetic sensor in the axial direction of the cylinder in detecting a rotation position of the cylinder by the sensor and reduces a necessary number of magnets.

Abstract: A switching device for a transfer switch has a pivotal body, a solenoid, a resilient pushing device and a main spring. The pivotal body has a pivotal axis, a first recess, a second recess and a connecting axis. The first and second recesses are defined adjacent to each other. The connecting axis is defined between the first and second recesses. The solenoid is connected to the pivotal body with a lever and has a driving shaft with a center line. The main spring has a connecting end being connected to the pivotal body at a point on the connecting axis. The lever has a center line. The connecting end of the main spring connected to the connecting axis is offset to the center line of the lever when the center line of the lever aligns with the center line of the driving shaft.

Abstract: An electric switch (1) includes a switching device (4), movable between its ON position and OFF position, for switching a current circuit. The switch (1) is combined with a magnetic circuit (28, 29) for electromagnetic undervoltage tripping. In the event of undervoltage, the magnetic circuit (28, 29), as it opens, shifts the switching device (4) to its OFF position. The switching device (4) shifted to its OFF position closes the magnetic circuit (28, 29) again. A linearly movable fixing slide (24) couples the switching device (4) with the magnet armature (28) of the magnetic circuit and fixes the magnet armature (28) on the magnet core (29) in the OFF position of the switching device (4).

Abstract: An electric circuit switching device comprises a group of closing contact pairs and a group of breaking contact pairs, each group having stationary contacts arranged circumferentially on an insulating panel, and a switching element; a unit for rotating the switching elements; and an electromagnetic drive providing translatory motion of the switching elements while closing and breaking the contact pairs. The unit for rotating the switching elements is a rotary electromechanical drive having a means for setting the angle of rotation of its output shaft depending on the position of the contacts to be switched on the insulating panel. The electromagnetic drive has two electromagnets, the first of which provides translatory motion of the switching element of the group of the closing contact pairs, and the second electromagnet providing translatory motion of the switching element of the group of the breaking contact pairs.

Abstract: The present invention relates to an optical-fiber switch. The switch is used in switching between at least two optical signals which are capable of being modulated with a broadband RF signal including digital signals. The switch is comprised of at least two optical-fiber cables for feeding the at least two optical signals to at least two fixed positions. An optical-fiber output cable is provided having one end which is movable between at least two positions which are directly adjacent said two fixed positions. A drive unit is provided for moving the optical-fiber output cable between the at least two positions, whereby the optical signals are selectively fed to the optical-fiber output cable.
