The protruding length size for stating the first contact arm is more than the protruding length size of the second contact arm so that when push card promotes movable contact spring to make
When stationary contact is in contact, first it can be in contact in movable contact close to the part of the first contact arm with stationary contact, close to second in movable contact
The part hysteresis of contact arm is in contact with stationary contact again, forms the contact of sound contact roll to prevent contact adhesion.
