Electromagnetic switch

An electromagnetic switch comprising:

• an electromagnetic module including first and second electromagnetic members, each of which includes a coil, a yoke disposed above said coil, and an armature disposed below said coil and movable upwardly when actuated by said yoke upon application of an electric current to said coil, said electromagnetic module further including first and second pushing units connected to and projecting upwardly and respectively from said armatures of said first and second electromagnetic members, and co-movable with said armatures, respectively;
• and
• a contact module including
• a fixed contact member disposed above said first and second electromagnetic members and including conductive first and second fixed contacts, and
• a movable contact member disposed between said electromagnetic module and said fixed contact member and including a movable seat with two opposite sides, and conductive first and second movable contacts which are respectively disposed at said opposite sides of said movable seat and which are vertically and respectively aligned with said first and second fixed contacts, said movable seat being pivoted to said fixed contact member so as to permit said movable contact member to be rotatable relative to said fixed contact member among a first angular position, in which said first movable contact is in electrical contact with said first fixed contact, whereas said second movable contact is spaced apart from said second fixed contact when said coil of said first electromagnetic member is actuated, a second angular position, in which said second movable contact is in electrical contact with said second fixed contact, whereas said first movable contact is spaced apart from said first fixed contact when said coil of said second electromagnetic member is actuated, and a normal angular position, in which said first and second movable contacts are spaced apart from said first and second fixed contacts, respectively, when said coils of said first and second electromagnetic members are disabled;
• wherein said first and second pushing units respectively extend toward said opposite sides of said movable seat in such a manner that said first pushing unit is moved upwardly upon actuation of said armature of said first electromagnetic member so as to move said movable contact member to said first angular position, and that said second pushing unit is moved upwardly upon actuation of said armature of said second electromagnetic member so as to move said movable contact member to said second angular position.
