| 41 | Electrical contactor | EP14194898.4 | 2014-11-26 | EP2881962A2 | 2015-06-10 | Connell, Richard |
An electrical contactor (10) comprises a first terminal (12) having a fixed member (30) with at least one fixed electrical contact (32), a second terminal (14), and at least one movable electrical contact (50) in electrical communication with the second terminal (14). A dual-coil actuator (64) is also provided and has a first drive coil (80) drivable to open and close the movable and fixed electrical contacts, and a second non-drive coil (82) feedback connected to induce a reverse flux to temper and stabilise a nett flux. Control of a delay time of the opening and closing electrical contacts is thus possible, so as to be at or adjacent to a subsequent or next zero-crossing of an associated AC load current waveform. A method of controlling electrical contact closing and opening delay, and a method of limiting or preventing electrical contact bounce and arc duration are also provided.

| The invention relates to a microsystem with an integrated reluctant magnetic circuit which subjects a mobile contact piece (20, 20') to an additional contacting force (F'), in the position with a closed electrical circuit, the intensity of which varies as a function of an alternating current (I) flowing across the electric circuit. According to the invention, the variations in said additional contacting force are used to permit the electric circuit to be opened when the current is below a threshold level. Said threshold level can correspond to the value for the appearance of an electric arc. | ||||||
| 44 | Snap-action switch for alternating current | EP83108928 | 1983-09-09 | EP0103284A3 | 1986-10-15 | Rossi, Guglielmo |
A snap-action switch, especially microswitch for alternating current comprises at least one stationary contact (2) on a stationary contact part (1) and at least one movable contact (4) on a movable contact part (3). In order to open the switch in the proximity of the zero crossing of the switch current, on the one contact part (1; 3) there is an electromagnet unit (8) excited by the switch current while on the other contact part (3: 1) is disposed an armature unit (12) made of ferromagnetic material which is located opposite the electromagnet unit (8) |

A switch assembly includes first and second contact members which are operatively provided to take one of two positions, a break-position in which the first and second contact members are separated from each other, and a make-position in which the first and second contact members are electrically connected with each other. Magnetic members are provided operatively in association with the first and second contact members to define a closed magnetic loop with a current path extending through the loop, when the first and second contact members are turned to the make-position. The magnetic members attract each other by the magnetic flux through the closed loop to maintain the first and second contacts in the make-position when the current flowing through the current path is not zero. Thus, the first and second contact members are permitted to return to the break-position at a zero crossing point of a.c. current flowing through the contacts. |

An electrical contactor (10) has a first terminal (12) having a fixed member (30) with at least one fixed electrical contact (32), a second terminal (14), and a busbar (16) connected to the second terminal (14). Two conductive movable arms (58, 60) are connected to the busbar (16) and have a contact (50) thereon. One arm (58) is biased-closed to contact the fixed electrical contact (32) in the absence of a separating force, and the other arm (60) is biased-open to be spaced away from the fixed electrical contact (32) in the absence of a closing force. The first and second movable arms (58, 60) and the busbar (16) are arranged so that, when the contacts close, contra-flowing current urges the movable arms (58, 60) towards the fixed member (30) to increase a force between the contacts (32, 50).

| In a method for disconnecting a switching contact from a mating contact in a switch which switches alternating current, a short mechanical pulse is applied to the switch with a pulse direction for disconnecting the contacts with a phase angle of approximately 13° before a next or a following zero crossing of the current. To this end, a piezoactuator is provided on the mating contact. Said piezoactuator can also measure the applied contact force, so that the pulse is triggered, in addition to said phase angle, only at a very low contact force which tends towards zero. | ||||||
