Patent number: 11222758Abstract: The construction comprises a rotary handle with a first pivot axis, a locking latch with a second pivot axis, a fixed bottom ring, a locking pin movable with the locking latch between a first position in which the rotary handle can be turned in relation to the bottom ring and a second position in which the locking pin prevents turning of the rotary handle in relation to the bottom ring, a shaft adapter rotationally movable against a spring force in relation to the rotary handle. The shaft adapter comprises a protrusion having a locking member which locks the locking pin into the first position when the torsional moment acting on the rotary handle exceeds the spring force acting on the shaft adapter causing a limited rotational movement of the shaft adapter in relation to the rotary handle.Type: GrantFiled: May 20, 2020Date of Patent: January 11, 2022Assignee: ABB Schweiz AGInventors: Juha Soldan, Matti Knuuttila

Patent number: 11069492Abstract: The construction includes a rotary handle turnable around a first pivot axis between an open- and a closed-position, a locking latch turnable around a second pivot axis between a locked position and a released position, a fixed bottom ring, a first locking pin movable in the longitudinal direction with the locking latch between a first position in which turning of the rotary handle is allowed and a second position in which turning of the rotary handle is allowed and a second position in which turning of the rotary handle is prevented. A second locking pin is movable between a first position in which turning of the locking latch between a locked-position and a released-position is allowed and a second position in which turning of the locking latch into the locked-position is prevented.Type: GrantFiled: June 16, 2020Date of Patent: July 20, 2021Assignee: ABB Schweiz AGInventors: Juha Soldan, Matti Knuuttila, Mikko Välivainio

Patent number: 10804056Abstract: An electrical switch. The electrical switch includes at least one fixed contact and a movable contact contacting the fixed contact. At least one shutter element is arranged to move in synchronism with the movable contact. The shutter element is positioned in an extended position between the fixed contact and the movable contact and in a contracted position outside the patch of the movable contact allowing the movable contact to turn from the open position to the closed position.Type: GrantFiled: April 17, 2019Date of Patent: October 13, 2020Assignee: ABB OyInventors: Fredrik Strand, Mikko Välivainio, Jukka Lintamo, Juha Soldan
