The partition wall includes a major part and an auxiliary part, the major part being provided with a local opening. An electromagnet assembly is received in the first receptacle of the base and includes an electromagnet and an armature. The armature includes an extending portion extending in a direction toward the second receptacle of the base through the local opening of the partition wall. The auxiliary part of the partition wall is disposed between the electromagnet and the extending portion of the armature. A contact section is received in the second receptacle of the base. An actuating member is arranged between the electromagnet assembly and the contact section, and includes an envelope part for enclosing at least a part of the extending portion of the armature. When the contact section is opened, the envelope part of the actuating member is supported by the auxiliary part of the partition wall.
