Claims

[Scope of utility model registration request]

(1) A fixed core to which an operating coil is attached and held on a mounting base, a movable core held by a crossbar facing the fixed core, and a fixed contact fixed to the main body frame and provided with a fixed contact; A movable contact is provided opposite to the fixed contact and has a movable contact held by a crossbar, and an excitation voltage is supplied to the operating coil to move the movable core toward and away from the fixed core and fix it as the crossbar slides. - An electromagnetic switch that opens and closes both movable contacts, consisting of a shield plate that covers the current-carrying part including the fixed contact, and an elastic engagement piece that extends from the shield plate and has an engagement part at its tip. Looking at the safety cover, a locking part is provided on the device main body side to which the engaging part of the safety cover locks, and the safety cover covers the current-carrying part of the device main body and is removably locked to the device main body. An electromagnetic switch with a safety cover, which is characterized by:

(2) Utility Model Registration Scope of Claim (1) In the device described in claim (1), the main body frame is provided with an arc cover that covers the movable contact, and the locking portion that locks the safety cover is the peripheral edge of the arc cover. An electromagnetic switch with a safety cover, characterized in that it is installed in.
