ABSTRACT:
A switch assembly includes a switch actuator assembly which is operable to actuate a plurality of switches. The switch actuator assembly includes a pushbutton which is manually depressed to move a core relative to a coil from a first position to a second position. As the core moves to the second position, the plurality of switches are actuated and a magnetic field from the core cooperates with a base or frame member to hold the core in the second position. As the pushbutton returns to its unactuated position, a force transmitting lever moves into an extended position in engagement with a coil switch actuator arm. Subsequent depressing of the pushbutton causes a drive pin connected with the pushbutton to depress the force transmitting lever to open a coil switch and deenergize the coil. As the pushbutton is subsequently released, the core and drive pin move upwardly. The coil switch then closes and a retainer pin connected with the core pushes the force transmitting lever back to a retracted position. A remote switch is provided to interrupt a circuit for energizing the coil.
