Abstract: A safety interlocking device for a switch includes a supporting member, an annular member, a locking lever, a limiting rod and a resilient member. A driving shaft of the switch is arranged through the supporting member and the annular member, the annular member rotates synchronously with the driving shaft, and the annular member is coupled to a wing block. The locking lever is hooked onto the safety device, the limiting rod is rotated when pushed by the safety device, and the rotation of the limiting rod rotates the locking lever. When the safety device is closed, the switch is turned on and the locking lever hooks onto the safety device so that the latter cannot be opened; and when the switch is turned off, the locking lever releases the safety device, while one end of the limiting rod limits the rotation of the annular member, thus limiting the switch's turn-on operation.

Abstract: A device is disclosed for switching an electrical switch on and off, with a drive shaft and an output shaft. The drive shaft and the output shaft run transversely with respect to one another and interact in such that a rotation of the drive shaft entails a rotation of the output shaft, the drive shaft being rotatable between an ON position and an OFF position, and the output shaft being rotatable between a switch-on position and a switch-off position. The output shaft is connected to the switch which can be switched to the switch-on and the switch-off position as a result of the rotation of the output shaft. The drive shaft and the output shaft are connected to one another via a displaceable sliding element which, during the rotation of the drive shaft, is displaced, and the output shaft is rotated by the sliding element in the course of displacement.

Abstract: A safety interlocking device for a switch is disclosed. In at least one embodiment, the safety interlocking switch includes a supporting member, an annular member, a locking lever, a limiting rod and a resilient member. A driving shaft of the switch can be arranged through the supporting member and the annular member, the annular member can be rotated synchronously with the driving shaft, and the annular member is further provided with a wing block. The locking lever can be hooked onto the safety device of the switch, the limiting rod can be rotated when pushed by the safety device, and the rotation of the limiting rod can make the locking lever rotate. When the switch is turned on, the locking lever hooks onto the safety device so that the latter cannot be opened; and when the switch is turned off, the locking lever releases the safety device, while one end of the limiting rod limits the rotation of the annular member, thus limiting the switch's turn-on operation.

In at least one embodiment, the output shaft is connected to the switch which can be switched on into the switch-on position as a result of the rotation of the output shaft and can be switched off into the switch-off position by rotation.
