Abstract

The magnetic actuator part of a gas safety valve is constructed with a C-shaped insulator which grips the base portion of a U-shaped magnet that is fastened to a base. The base has welded to it a projecting contact pin. The coil of the electromagnet is fusion welded at both its ends: at its first end it is attached to a plate which connects to the center pin; at its second end it is attached to the contact pin to which it lies transverse. The construction facilitates good electrical connections between dissimilar materials and permits rapid assembly by a robot.
