Abstract: Techniques for managing a distributed control system for a motor control switch are described. A request to implement a first controller for a motor control switch is received. Embodiments determine a plurality of functional modules for the first controller. Each of the plurality of functional modules comprises an instance of computer logic configured to perform a respective function. A respective Motor Control Function Set (MCFS) for performing the respective function of each of the plurality of functional modules is determined. One or more of a plurality of configurable hardware blocks are allocated to each of the plurality of functional modules. Embodiments configure each of the plurality of configurable hardware blocks based on the MCFS of the functional module to which the respective configurable hardware block is allocated. The configured plurality of configurable hardware blocks is executed as a distributed system to control the motor control switch.

Abstract: A contact wear detector includes an electrical contact 100 having a base layer 110 composed of a first material and a contacting layer 120 composed of a second material, to electrically contact an opposing contact in the circuit. The base layer is capable of having portions exposed through worn areas 125 of the contacting layer. The first material of the base layer is configured to form an arc 210 between the portions of the base layer exposed through the worn areas and the opposing contact when the contacts separate. The arc thus formed emits light 212 having a characteristic optical spectrum of the first material. An optical detector 220 is proximate to the electrical contacts, to detect the characteristic optical spectrum of the light emitted by the arc between the portions of the base layer exposed through the worn areas and the opposing contact.
