Abstract
Abstract An integrated electrical control device in which an electrical coil and connectors therefor are embedded in a body of plastic or other relatively rigid nonconducting material, and a switch disposed in a cavity in said body interconnects said conductor members and is adapted to be operated by an armature held by the core of said coil. The switch may consist of a leaf spring rigidly connected to one of said conductor members and yieldably connected to the other of the conductor members, and is operated by the operation of said armature through a stem extending inwardly into the body to the switch. The coil and conductor members are molded integrally with the plastic body.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
143 words
An integrated electrical control device comprising a unitary body of electrical nonconducting material, an electrical coil embedded in said body, a cavity in said body, a pair of electrical connector members embedded in said body and connected to said coil and having means for connection to a source of current for said coil, said members extending parallel with one another on either side of said coil and the inner ends of said members projecting into said cavity, an electrical switch means in said cavity for controlling the current through said coil interconnecting the inner ends of said members and including a leafspring switch element attached to one of said members and yieldably in contact with the other of said memberS, and a stem engaging said element near the yieldable end thereof and projecting outwardly from said body for operation of said switch element.
Claim 2
Dependent Claim
143 words
An integrated electrical control device comprising a unitary body of electrical nonconducting material, an electrical coil embedded in said body, a cavity in said body, a pair of electrical connector members embedded in said body and connected to said coil and having means for connection to a source of current for said coil, said members extending parallel with one another on either side of said coil and the inner ends of said members projecting into said cavity, an electrical switch means in said cavity for controlling the current through said coil interconnecting the inner ends of said members and including a leafspring switch element attached to one of said members and yieldably in contact with the other of said memberS, and a stem engaging said element near the yieldable end thereof and projecting outwardly from said body for operation of said switch element.
Claim 3
Dependent Claim
43 words
