摘要： A rotary switch with three controlling positions in a circulating sequence of "Off", a small output, and a large output, includes a cover and a base connected with the cover. A rotor which is made of an electrically insulating material and provided with three cam parts along its circumferential periphery, is mounted in the base to rotate an electrically conductive plate with two side portions engaged with two of the cam parts. A first, second and third leaf spring respectively has a fixed end connected with an input wire, an input end of a diode, and an output wire of the switch and a free end extending toward the rotor. The fixed end of the third leaf spring is also connected with an output end of the diode. When the switch is set to the "Off" position, the first leaf spring contacts with the rotor, and the other two leaf springs contact with the conductive plate via the two side portions thereof.

摘要： A switching mechanism in a star-delta-switch with a rotatable and axially displaceable switch-shaft prevents rotation of the switch-shaft from the off- to the delta-connection position in the direction of rotation from the delta-connection to the off-position in one of the axial positions while axial displacement of the switch-shaft to another axial position enables the switch-shaft to be rotated from the off- to the delta-connection, rotation of the switch-shaft in the other axial position causing the switching mechanism to reset to the one axial position.

摘要： The drawings illustrate a double pole, double throw switch for use in selectively controlling energization of either a first or second electric circuit. The switch includes two sets of first, second and third terminals, with each of the second terminals being offset in opposite directions from one another, and a pivotally mounted actuator button. A pair of legs are formed on the inner portion of the actuator button for carrying first and second contact strips, the latter being mounted for universal movement with respect to the second terminals so as to normally contact respective opposite first or third terminals. The legs are moveable in response to initial movement of the actuator button in either direction so as to selectively cause one of the first and second contact strips to pivot overcenter on the second terminal into engagement with the other of the first or third terminals to provide a conductive path between respective first or third terminals and thereby complete one of the first or second electric circuits. The legs are further moveable in response to continued movement of the actuator button so as to cause the first and second contact strips to slide across the respective first or third terminals in a cleaning action.

摘要： Disclosed is an improved switch particularly adapted to be used as a coaxial cable switch for cable television systems because of its superior isolation of the signal inputs. The switch comprises an electrically insulating body, first, second and third terminals located on the body in spaced relationship, a movably mounted contact, which is movable along a predetermined path to form alternative conductive paths between the first terminal and either of the second or third terminals, and a partition means between said terminals and located adjacent the path of the contact to form a barrier to radiated signals from whichever of the second and third terminals that is not in contact with the movable contact. Additionally, terminating means for the unused terminal and/or shielding means to further isolate the unused terminal from the used terminal can be provided.

摘要： The present invention relates to a rotary switch with multi-level, the rotary base drives the first conductive sheet to rotate with the second conductive sheet when the rotary shaft is rotated, and the second conductive sheet leaves one of the conductive contact elements; the position end of the second conductive sheet is pressed by one positioning surface during the rotation, and the second spring stores energy; the second spring then releases the energy to the fourth end of the second conductive sheet, and the position end of the second conductive sheet slides on one positioning surface until the position end of the second conductive sheets is positioned solidly between two positioning surfaces; so that, the material cost in production can be lower down, and life time of the rotary switch can be increased.
