Sliding electrical switch
View Patent ↗A sliding electrical switch comprising a first slider which is able to establish a first electrical switching channel, a first actuator for the first slider, a second slider which is able to establish a second electrical switching channel, a second actuator for the second slider, and a common return spring which is a compression spring which is mounted axially compressed between the first and second sliders and which simultaneously stresses each of the two sliders towards its idle axial position.
1. An electric slider switch comprising:
a switch housing delimiting an internal chamber;
a first slider, arranged in said internal chamber and which is guided to slide along a horizontal axis of the switch housing so as to be movably mounted in a first direction between an idle axial position which is defined by a first fixed end stop element of the switch housing, and an active axial position in which it contacts a first electricity conducting means, arranged in the internal chamber, to establish a first electrical switching channel;
a first actuator which is connected in axial relationship with the first slider and which extends out of the switch housing to enable the first slider to be actuated in said first direction towards its active axial position;
a second slider, arranged in said internal chamber and which is guided to slide along said axis of the switch housing so as to be movably mounted in a second direction, opposite to said first direction, between an idle position which is defined by a second fixed end stop element of the switch housing, and a second active position in which it contacts a second electricity conducting means, arranged in the internal chamber, to establish a second electrical switching channel;
a second actuator which is connected in axial relationship with the second slider and which extends out of the switch housing to enable the second slider to be actuated in said second direction towards its active axial position; and
a common return spring that is a compression spring that is mounted axially compressed between the first and second sliders and which simultaneously stresses each of the two sliders towards their respective idle axial positions.
2. The switch according to claim 1 , characterized in that, in the idle position of the associated slider, each actuator is axially arranged in the vicinity of the centre of the switch and, in the active position of the associated slider, is arranged in the vicinity of an axial end of the switch.
3. The switch according to claim 2 , characterized in that, in the idle position of the two sliders, the two actuators axially arranged in the vicinity of the centre of the switch define between them a recess which is able to receive a switch control button.
4. The switch according to claim 1 , characterized in that, in the idle position of the associated slider, each actuator is axially arranged in the vicinity of an axial end of the switch and, in the active position of the associated slider, each actuator is arranged in the vicinity of the centre of the switch.
5. The switch according to claim 1 , characterized in that the common return spring is a helical compression spring that is guided axially in the switch housing.
6. The switch according to claim 1 , characterized in that each slider comprises:
an axial guidance branch for guiding the slider in the switch housing; and
a transverse branch, that is arranged at an axial end of the axial guidance branch, that cooperates with an axial end of the common return spring and that, in the idle position of the slider, is arranged at an axial end of the internal chamber.
7. The switch according to claim 6 , characterized in that each slider is generally U-shaped and includes another axial branch for guiding the slider in the switch housing that is connected to said axial guidance branch by the transverse branch, and in that the common return spring is housed between the two axial branches of each slider.
8. The switch according to claim 7 , characterized in that said other axial guidance branch of a slider bears means which cooperate with said electricity conducting means associated with said slider.
9. The switch according to claim 6 , characterized in that said transverse branch bears means which cooperate with said electricity conducting means associated with said slider.
10. The switch according to claim 1 , characterized in that each slider extends in a horizontal plane and is delimited by two parallel horizontal faces, and in that the two sliders are superposed in the internal chamber.
11. The switch according to claim 1 , characterized in that the axial actuation travel of each of the two sliders is equal.
12. The switch according to claim 1 , characterized in that it includes an end stop means so as to limit the simultaneous travel, one towards the other, of the two sliders.
13. An electric slider switch comprising:
a switch housing delimiting an internal chamber;
a first slider, arranged in said internal chamber and which is guided to slide along a horizontal axis of the switch housing so as to be movably mounted in a first direction between an idle axial position which is defined by a first fixed end stop element of the switch housing, and an active axial position in which it contacts a first electricity conducting means, arranged in the internal chamber, to establish a first electrical switching channel;
a first actuator which is connected in axial relationship with the first slider and which extends out of the switch housing to enable the first slider to be actuated in said first direction towards its active axial position;
a second slider, arranged in said internal chamber and which is guided to slide along said axis of the switch housing so as to be movably mounted in a second direction, opposite to said first direction, between an idle position which is defined by a second fixed end stop element of the switch housing, and a second active position in which it contacts a second electricity conducting means, arranged in the internal chamber, to establish a second electrical switching channel;
a second actuator which is connected in axial relationship with the second slider and which extends out of the switch housing to enable the second slider to be actuated in said second direction towards its active axial position;
wherein, in the idle position of the associated slider, each actuator is axially arranged in the vicinity of the centre of the switch and, in the active position of the associated slider, is arranged in the vicinity of an axial end of the switch; and
a common return spring that is a compression spring that is mounted axially compressed between the first and second sliders and which simultaneously stresses each of the two sliders towards their respective idle axial positions.
