- the control device 1 comprises a switch 42 capable of supplying or removing the low voltage supply from the actuator 10.
- the switch 42 is provided with a control blade 43 on which the finger 41 of the selector 39 can come in support.
- the finger 41 of the selector 39 is separated from the control blade 43 or at the very least exerts a very slight pressure on the control blade 43.
- the actuator 10 is not supplied with power and is therefore unable to move.
- the selector finger 41 is in contact with the control blade 43 and exerts sufficient support to make the switch 42 on and authorize the supply of the actuator 10.
- the selector 39 comprises a lower part 44 provided with a central notch 45 and two pairs of locking teeth
- pairs of teeth 46 and 47, 48 and 49 are arranged on one side and the other of the notch 45. Each tooth of a pair is separated from the other tooth of the same pair by a space 50.
- the "ON” button 38 includes a lateral protuberance 51 arranged so that when the selector 39 is in the first position, any attempt to depress the "ON” button 38 is prevented by the protuberance 51 of said “ON” button.
- the "STOP" button 37 includes a lateral protuberance 52 arranged so that when the selector 39 is in the first position, any attempt to depress the "STOP” button 37 is prevented by the protuberance 52 abutting the tooth 48 of the pair of teeth 48 and 49 of the selector 39, when the selector 39 is in the third position a possible attempt to depress the "STOP” button 37 is prevented by the protuberance 52 coming into abutment on the end tooth 49 of the pair of teeth 48 and 49 of the selector 39, and when the selector 39 is in the second position an attempt to depress the "STOP” button 37 is authorized, the protuberance 52 being able to pass through the space ace 50 between teeth 48 and 49.
- the control device 1 further comprises a first slide 53 movable in translation in a direction perpendicular to that of the selector 39.
- the first slide 53 is provided with a surface 54 of contact with the finger 36 of the cam 3, and a protuberance 55 capable of cooperating with the selector 39.
- a spring 56 exerts on the first slide 53 a force directed towards the rack 30.
- the selector 39 comprises a shoulder formed by two parallel surfaces 57 and 58 and a surface 59 perpendicular to the previous ones and separating them.
- the protuberance 55 of the first slide 53 can slide on one or the other of the parallel surfaces 57 and 58 and can block a movement of the selector 39 whose perpendicular surface 59 abuts on said protuberance 55.
- the selector 39 can be freely moved between its second and third positions whatever the position of the first slide bucket 53.
- the selector 39 can be freely moved from its first position to its second position whatever the position of the first slide 53.
- movement of the selector 39 from its second position to its first position is authorized if the first slide 53 is is in a position such that the perpendicular surface 59 is free to move relative to the protuberance 55, in other words, if the spring 56 is compressed under the action of the finger 35 on the contact surface 54.
- the control device 1 further comprises a second slide 60 movable in translation in a direction perpendicular to that of the selector 39.
- the second slide 60 includes a foot 61 capable of projecting into the notch 45 when the selector 39 is located in its first position and, thus, to block the selector 39 in said first position. This position of the second slide 60 is said to be active. In the inactive position, the foot 61 is released from the notch and is unable to block the selector 39.
- the second slide 60 includes a grip button 62 capable of projecting through an opening of the cover 12 so that a user can move it between an active position and an inactive position.
- the second slide 60 may include, near the grip button 62, a hole 63 in which a user can pass the ring of a padlock, not shown, when the second slide 60 is in the active position. In the inactive position, only the gripping button 62 projects from the cover 12. Complete extraction of the second slide 60 by pulling it from the active position is prohibited, the foot 61 coming into contact with the bottom of the notch 45.
- circuit breaker actuating device 1 can successively take one of the configurations from a plurality of configurations in response to the change of state of an electrical system (not shown) and to the action of the electromagnet and actuator return spring 10.
- the "STOP" button 37 can be pressed manually while the control device 1 is in the "ON” position in FIG. 12. This action causes the cam 3 to rotate clockwise and the frame 13 to rotate counterclockwise, thus opening the circuit breaker contacts while positioning the lever 5 to the left of the central line 64 and near the first flange 28. This leads the control device to the "OFF" position in FIG. 15. To return to the "ON” position in FIG. 12, the "ON” button 38 is pressed manually. This action turns the cam 3 counterclockwise, thereby closing the circuit breaker contacts while returning the lever 5 to a position on the right of the central line 64 and near the second edge 29.
- the circuit breaker trips and drives the control device 1 to the "TRIGGERED” position in Figure 13.
- the control device control 1 is reset by the action of the electromagnet of the actuator 10 and brought to the "RESET” position in FIG. 14.
- the control device 1 is then placed in the "OFF” position in FIG. 15 by returning the actuator 10.
- the "ON" button 38 is manually depressed as described above. This action turns the me 3 counterclockwise, thereby closing the circuit breaker contacts while returning the lever 5 to a position located to the right of the central line 64 and near the second flange 29.
- buttons and the actuator are only locked from the tilted position to the right of the cam as shown in FIG. 7.
- This locking is effected by moving the selector to its first position and can be secured by means of the second slide capable of locking the selector in its first position and capable of cooperating with a padlock.
- the user has the choice between the second and third positions of the selector, the first slide preventing movement to the first position.
