Electric circuit with speed control and diode separation for use with an electrically actuatable mechanism

摘要

An electric circuit with speed control and diode separation for use with an electrically actuatable mechanism. An operator input provides a signal to a controller of the electric circuit. The controller causes a MOSFET relay to provide a voltage to the electrically actuatable mechanism. The relay is adapted to vary the voltage in response to pulse width modified signals from the controller.

1. An electric circuit for actuating an electrically actuatable mechanism comprising:
a controller; multiple operator inputs each of which, when actuated, changes a boolean signal to the controller; a first relay adapted to provide a voltage to the electrically actuatable mechanism in response to a control signal from the controller, a second relay electrically connected to an output of the controller and operative to control power to the controller in response to actuation of one of the operator inputs, a respective diode associated with each operator input, wherein each diode is associated with the second relay preventing a back-feeding of the voltage from the second relay.
