Abstract
A motor driven switch for use in operation between high current electrical systems and low current electrical systems. The motor driven switch includes a control circuit for operating the switch, which includes at least one switch contact movable between electrically open and closed positions. The switch is operated by a reversible direct current motor having a shaft rotatable in opposite rotary directions, upon control of the switch circuitry. The switch contact is operable to conduct high currents, and the direct current motor and associated control circuitry are operative to be controlled by low current systems. In a preferred embodiment, the motor driven switch controls distribution of current within an automotive electrical system.
Claims11
A system for controlling a motor driven switch comprising:
- a switch having at least one switch contact moveable between electrically closed and open positions;
- a reversible direct current motor having a shaft rotatable in first and second opposite rotary directions;
- means connected to said motor shaft for operating said at least one switch contact for electrically opening and closing the switch responsive to rotation of said motor shaft in first and second opposite rotary directions;
- command circuit means responsive to a first condition for generating a first signal and responsive to a second condition for generating a second signal;
- and
- control circuit means responsive to said first signal for driving said direct current motor shaft in the first rotary direction and responsive to said second signal for driving said direct current motor shaft in the second opposite rotary direction;
- whereby the motor driven switch is controlled between the open and closed positions by electrical signals.
A system for controlling a motor driven switch, comprising:
- a switch adapted to be connected in series with at least one load;
- means for opening and closing said switch including a direct current motor operative to drive a rotary shaft, and means controlled by said rotary shaft for operating said switch between electrically open and closed positions;
- first means for generating a first output signal;
- second means for generating a second output signal;
- timer means responsive to said first output signal for generating a timing output signal a time delay period after said first output signal;
- control driver circuitry responsive to said timing output signal for operating said motor in order to open said switch, and responsive to said second output signal for operating said motor in order to close said switch.
A system for controlling a motor driven switch comprising:
- switch means for switching between electrically closed and electrically open positions;
- a reversible direct current motor rotatable in clockwise and counterclockwise rotary directions;
- means responsive to the rotation of said motor in opposite rotary directions for operating said switch means in order to electrically open and close said switch;
- command circuit means responsive to one condition for generating a first command signal and responsive to another condition for generating a second command signal, said command signals being relatively low and high voltage signals compared to each other;
- and
- control circuit means responsive to said command signals for driving said direct current motor in clockwise and counterclockwise rotary directions whereby the motor driven switch means is controlled between electrically open and closed positions by electrical signals.
