Abstract
An integral series parallel changeover and power dynamic brake controller apparatus for a transit vehicle disclosed. The controller utilizes a single cam shaft to operate switches for the series parallel function and the power brake function. The apparatus includes a cam shaft return spring which is latched out during normal operation. Upon a power failure the spring is released. An escapement mechanism is provided to slow the rotation of the cam shaft upon the spring being released to provide for desirable sequential operation of the power circuit.
