Abstract
A starting switch assembly is integrally formed with a terminal connection board and is adapted to be actuated by a conventional centrifugal actuator. The switch assembly is constructed so that the electrical contact points of the assembly abut one another under a predetermined pressure independent of the forces exerted on other structural components of the assembly. In the preferred embodiment, the terminal connection board is used to connect external power leads to the dynamoelectric machine. The switch assembly includes a terminal block integrally formed with the terminal connection board. Various windings of the dynamoelectric machine are connected to the power leads by switch assembly operation. The assembly includes a switch arm which is mounted for movement between at least first and second positions. The switch arm is designed to engage and disengage respective ones of a plurality of electrical contacts as the switch arm moves between positions. The switch assembly also includes provisions for some lost motion movement before switch operation in each direction of switch arm movement.
