Electric control device

Abstract

Abstract An electric control device or contactor devoid of a mounting bracket and adapted for mounting on a mounting panel and comprising an electrically insulating housing, a stationary contact structure and a movable contact structure within the housing; the device also comprising electromagnetic means for actuating the movable contact carrier structure between opened and closed positions with respect to the stationary contact structure, the movable contact carrier structure also comprising a magnetic coil, an armature, and a magnet; the housing having walls forming an axial opening through which the movable contract structure is inserted or withdrawn from the housing; and means for detachably mounting the assembly of the movable contact structure, armature, the coil, and the magnet in an operative position within the housing and said means including a detachable clip mounted on two opposite housing walls and including a retaining pin extending through an opening in the magnet which pin includes opposite end portions seated within corresponding notches in the housing and retained therein by the clip. The stationary contact structure includes a conducting strap having a downturned portion which strap includes opposite end notches for engagement with corresponding projections in the housing to prevent longitudinal movement of the strap and the downturned portion includes an aperture adapted to receive corresponding projection of the housing, whereby the strap is detachably seated in place on the housing.
