Title:
GROUNDING SWITCH
Document Type and Number:
Japanese Patent JP2020009706
Kind Code:
A
Abstract:
To prevent heat generation while suppressing repulsion between a mover and a stator at the time of short circuit.SOLUTION: A grounding switch (10) includes a mover (12) and a stator (14) that are provided so as to be able to contact and separate from each other, energize in a contact state, and cut off energization in a separated state. The stator has a first area (14A) where the separated mover moves in the contact direction and comes into first contact with the stator, and a second area (14B) where the mover moves in the contact direction and comes into contact with the stator after contact with the first area. The first region is configured to include a material having higher electric resistance than the second are.SELECTED DRAWING: Figure 1
