ABSTRACT:
This invention provides a novel and unique electric control device which utilizes a new auxiliary contact device. This new auxiliary contact device has a contact-carrying structure that is directly engaged with the operating mechanism of the electric control device whereby the operating mechanism directly moves the auxiliary contact device to all operating positions eliminating any requirement for biasing the auxiliary contacts into any normal position.
