Abstract

A rotary switch includes an operating mechanism, an on-off apparatus, and a tripping component. The operating mechanism includes an energy storage component and a drive component. The drive component is in driving connection with the energy storage component and the on-off apparatus. The energy storage component includes a latch and an energy storage spring that cooperates with the latch. The energy storage spring can be connected to the latch and the drive component in a snap-fit manner, such that rotation of the drive component stores energy in the energy storage component. Rotation of the drive component also drives the on-off apparatus to an on position. The latch the tripping component interact such that the latch locks or unlocks the energy storage spring.

Claims20

Dependent claims

A rotary switch comprising an operating mechanism, an on-off apparatus, and a tripping component, wherein the operating mechanism comprises an energy storage component and a drive component separately in driving connection with the energy storage component and the on-off apparatus;

and the energy storage component comprises a latch and an energy storage spring that cooperates with the latch,
wherein the energy storage spring is configured to be separately connected to the latch and the drive component in a snap-fit manner,
wherein the drive component is rotated, so that the energy storage component stores energy and the drive component is used to drive the on-off apparatus to be switched on,
wherein the latch cooperates with the tripping component, so that the latch locks or unlocks the energy storage spring, and
wherein based on the energy storage spring being unlocked, the energy storage spring drives the drive component to rotate to a switch-off position of the on-off apparatus.
