Operating mechanism, change-over switch and power distribution equipment
ActiveCN222637085Ureliable stopPrevent unstable motion conditionsContact driving mechanismsSwitch power arrangementsControl engineeringTransfer switch
The utility model provides an operating mechanism, a change-over switch and power distribution equipment, and relates to the technical field of low-voltage electrical appliances, and the operating mechanism comprises a mounting base, and an output member, a first stop member and a second stop member which are movably mounted on the mounting base, and the first stop member and the second stop member are respectively located at two opposite sides of the output member. When the output piece is located at the double-opening position, the output piece abuts against the first limiting part of the first stop piece and the second limiting part of the second stop piece, and when the output piece is located at the common closing position and the standby closing position, the output piece does not abut against the first limiting part and the second limiting part. When the output piece is switched from the double-opening position to the common closing position or the standby closing position, the first stopping piece and the second stopping piece do not stop the switching process, and when the output piece is switched from the common closing position or the standby closing position to the double-opening position, the first stopping piece and the second stopping piece abut against the two opposite sides of the output piece, so that the switching process is stopped. It can be ensured that the output piece reliably stops at the double-division position.
