For example, "connected" can be a wall-mounted connection, a detachable connection, or an integral connection, it can be a mechanical connection, an electrical connection, a direct connection, or an indirect connection through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0024] Referring to Figures 1-4 , this embodiment provides a toggle switch, including: a metal insert 15, the metal insert 15 is divided into a first group of metal inserts for serving as COM, a second group of metal inserts for connecting to the A light source, a third group of metal inserts for connecting to the B light source, and a knob 10;

[0025] The knob 10 drives the contacts on the contact piece 11 to connect the second group of metal inserts to COM, or connect the third group of metal inserts to COM, or connect the second group of metal inserts and the third group of metal inserts to COM at the same time;

[0026] The second group of metal inserts includes a first part on one side of the first group of metal inserts and a second part on the other side of the first group of metal inserts;

[0027] During the process that the knob 10 drives the contact on the contact piece 11 to move, the first part is connected to COM. Before the contact disconnects the first part from COM, the contact first connects the second part to COM; during the process that the knob 10 drives the contact on the contact piece 11 to continue moving, before the contact disconnects the second part from COM, the contact first connects the third set of metal inserts to COM; during the process that the knob 10 drives the contact on the contact piece 11 to continue moving, after the contact disconnects the second part from COM, the contact maintains the connection between the third set of metal inserts and COM.

[0028] Specifically, the first part includes a first insert 1 and a fifth insert 5 arranged vertically along the width direction of the switch. The length of the first insert 1 along the moving direction of the knob 10 is greater than that of the fifth insert 5. The first set of metal inserts includes a second insert 2 and a sixth insert 6 arranged vertically along the width direction of the switch; one end of the sixth insert 6 close to the fifth insert 5 protrudes outward from the second insert 2 and partially coincides with the first insert 1. And the second part is arranged on the side of the sixth insert 6 away from the fifth insert 5; the side of the sixth insert 6 away from the fifth insert 5 is concave with respect to the second insert 2 so that the second insert 2 partially coincides with the seventh insert 7. The third set of metal inserts includes a third insert 3, a fourth insert 4 and an eighth insert 8 arranged vertically along the width direction of the switch; the third insert 3 and the fourth insert 4 are located on the side of the second insert 2 away from the first insert 1 and are kept electrically connected; the eighth insert 8 is located on the side of the seventh insert 7 away from the sixth insert 6.

[0029] In this embodiment, there are two contact pieces 11, which are arranged at intervals along the width direction of the switch and are divided into an upper piece and a lower piece. Two contacts are arranged on each contact piece 11, and the contacts are arranged at intervals along the length direction of the switch. The switch further includes a base 13 and a cover plate 14. A card slot is arranged on the upper surface of the base 13 along the length direction, and ribs for clamping with the card slot are arranged on both sides of the cover plate 14 along the length direction; the free ends of the ribs extend outwards on both sides to form limiting surfaces that cooperate with the two side walls of the card slot.

[0030] In order to electrically connect the switch and the circuit board, relief openings are arranged at intervals on both side surfaces of the base 13 along the width direction; the pins of the first set of metal inserts, the second set of metal inserts and the third set of metal inserts are exposed outside the base 13 through the relief openings.

[0031] Combined with Figure 5 The operation of the toggle switch is described as follows:

[0032] In the first gear (the leftmost position of the toggle switch), the contacts on the upper piece of the contact piece 11 connect the first insert 1 and the second insert 2, and the contacts on the lower piece of the contact piece 11 connect the fifth insert 5 and the sixth insert 6, that is, A and COM are connected, and the A light source is on.

[0033] In the 1.5th gear (when the toggle switch transitions from the left to the middle), the contacts on the upper piece of the contact piece 11 still connect the first insert 1 and the second insert 2. Before the contacts on the lower piece of the contact piece 11 connect the sixth insert 6 and the seventh insert 7, even if there is a disconnection, since the first insert 1 and the second insert 2 are connected, A and COM are still connected, and the A light source is on until the sixth insert 6 and the seventh insert 7 are connected. Then, during the continuous movement towards the middle, the contacts on the upper piece of the contact piece 11 disconnect the connection between the first insert 1 and the second insert 2. Since the sixth insert 6 and the seventh insert 7 are already connected, A and COM are still connected, and the A light source is on.

[0034] In the second gear (the middle position of the toggle switch), the contacts on the upper piece of the contact piece 11 connect the second insert 2, the third insert 3, and the fourth insert 4. At this time, B is connected to COM, and the contacts on the lower piece of the contact piece 11 still connect the sixth insert 6 and the seventh insert 7. A and COM are still connected. At this time, the A light source and the B light source are on together.

[0035] In the 2.5th gear (when the toggle switch transitions from the middle to the rightmost), the contacts on the upper piece of the contact piece 11 still connect the second insert 2, the third insert 3, and the fourth insert 4. At this time, B is connected to COM, and the contacts on the lower piece of the contact piece 11 may disconnect the connection between the sixth insert 6 and the seventh insert 7. A and COM are disconnected. At this time, the B light source is on.

[0036] In the third gear (the rightmost position of the toggle switch), the contacts on the upper piece of the contact piece 11 still connect the second insert 2, the third insert 3, and the fourth insert 4. At this time, B is connected to COM, and the contacts on the lower piece of the contact piece 11 connect the sixth insert 6 and the connection of the eighth metal insert. B and COM are connected. At this time, the B light source is on.

[0037] The above process not only realizes the accurate switching of three color temperatures but also ensures that there is no possibility of complete disconnection during the switching process.

[0038] The above is only the preferred specific implementation manner of the present utility model and does not limit the patent scope of the present utility model. All technical equivalent transformations made using the content of the specification of the present utility model fall within the protection scope of the present utility model.
