Document Type and Number:
WIPO Patent Application WO/2014/167607
Kind Code:
A1
Abstract:
This circuit switchgear has a housing, a handle (100), and a handle spring (SP1). Said handle spring (SP1) comprises a coil spring that biases the handle (100) in a first direction that corresponds to the circumferential direction of the handle (100) and exerts an elastic force in a second direction that is parallel to the axis of rotation of the handle (100). The handle (100) has a temporary locking part that temporarily locks a second end section of the handle spring (SP1), which is compressed in the direction opposite the aforementioned second direction and is attached to the abovementioned housing. Said temporary locking part is designed so as to release the aforementioned second end section when, with the second end section held by the housing, the handle (100) rotates in the direction opposite the abovementioned first direction.
