ABSTRACT:
A motor protector having a can and an internal electrical contact is hermetically sealed to a disk-shaped header of conductive material, the header having a flattened edge for orientation in the can during fabrication of the protector and having spaced conductive pins sealed in and insulated from the header. A heater-support having holes for fabrication is bonded to one conductive pin, a bimetallic element on the support has a plane parallel to the axes of the pins and has a contact element normally contacting the can contact. A heater is bonded to each of the electrically conductive pins spaced from the movable contact and in a plane parallel to the axes of the conductive pins. In making the motor protector a fixture has one depression with pins mating with the support apertures and has a second depression receiving the header in an upright position and adjacent the first depression. The support is placed on the fixture with the pins extending therethrough and the header is oriented in its depression with one of the pins header resting against the support and is bonded to the support. The movable contact is disposed in its depression and welded to the support. Slider brackets receive and position the heater on the pins to which they are secured. The formed motor protector portion is placed in and hermetically sealed to the can with the contact within the can disposed against the contact element on the movable contact member.
