Title: The Innovations of Donald F. Swietlik

Introduction

Donald F. Swietlik is a notable inventor based in Waukesha, WI (US). He holds a total of 7 patents that showcase his contributions to the field of electrical engineering. His work primarily focuses on electromagnetic operators and electrical contactors, which are essential components in various electrical systems.

Latest Patents

Among his latest patents is the "Electromagnetic operator for an electrical contactor and method for controlling same." This invention features an electromagnetic operator that includes first and second coils wound coaxially. An armature partially surrounds the coils to channel flux during energization. The armature is designed to be formed of a bent plate and secured to a ferromagnetic support. A control circuit applies energizing signals to the coils during operation, with both coils energized during an initial phase. One coil is subsequently released or de-energized automatically, while a timing circuit removes current from the second coil after a variable time period, which may depend on the configuration of the timing circuit.

Another significant patent is the "Electric contactor housing." This invention provides a unitary housing structure for an electrical switching device, such as a three-phase contactor. The housing includes internal partitions that separate the operator section from contact sections and isolate phase sections from one another. These partitions are contiguous with one another and with the side walls of the housing, inhibiting plasma flow within the housing cavities. The housing is made of a thermoplastic material molded as a single piece, with shields within the phase sections to protect against plasma and arcs.
