Claims

[Scope of utility model registration request]

(1) An electromagnetic contactor in which an assembly of a movable contact support and a movable iron core is inserted into a box-shaped case with a main fixed contact on the top surface and an opening at the bottom and assembled through the bottom opening. In the case where the auxiliary switch is incorporated into the case, the case is divided into upper and lower halves, an upper case and a lower case that can be connected to and separated from each other, and the normally closed fixed contact of the auxiliary switch is inserted into the upper case. An electromagnetic contactor characterized in that normally open fixed contacts of the auxiliary switch are fixed to the lower case side, and a movable contact of the auxiliary switch is installed in the assembly.

(2) Scope of Utility Model Registration Claims In the item described in paragraph 1, the lower case is formed as a bottomed box having a lower bottom, and a fixed iron core and an electromagnetic coil are housed and equipped within the lower case. An electromagnetic contactor characterized by:
