Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1 and 2, the utility model provides a technical scheme: the control device for controlling the illuminator to supply power and illuminate comprises a shell 1, wherein a circuit board is arranged in the shell 1, a plurality of load circuits (shown in figure 3) with different resistance values are arranged on the circuit board, a first wiring terminal 2 and a second wiring terminal 3 are respectively arranged at two ends of the shell 1, one ends of the load circuits with different resistance values are connected with the first wiring terminal 2, and the second wiring terminal 3 is connected with an LED lamp. A circular contact disc 12 is also arranged in the shell 1, the circular contact disc is fixed in the shell 1, a plurality of contacts 11 are arranged on the circular contact disc 12, the other ends of a plurality of load circuits with different resistance values in figure 3 are respectively connected with the contacts 11 on the circular contact disc 12 in a one-to-one correspondence manner,

the shell 1 is also provided with a knob 4, the knob 4 is connected with a rotating rod 5, the bottom of the rotating rod 5 is provided with elastic contacts 10, and each contact 11 and the elastic contacts 10 are matched one by one to be equivalent to a switch K shown in figure 3. The rotary rod 5 is arranged in a sleeve 6, at least one concave hole 7 is formed in the rotary rod 5, a spring 8 is arranged in the concave hole 7, a ball 9 is arranged on the outer side of the spring 8, a plurality of grooves (not shown in the figure) are formed in the inner peripheral surface of the sleeve 6, and the groove setting angles correspond to the contact setting angles on the circular contact disc one by one. When the knob is rotated to the position that the concave hole 7 is opposite to the groove, the ball 9 can be clamped into the groove under the action of the elastic force of the spring, so that the rotating rod is relatively fixed, the elastic contact 10 just contacts with the contact 11, the situation that the knob is rotated to move excessively can not occur by adopting the structure, and the good contact between the elastic contact 10 and the contact 11 can be ensured. In order to ensure better positioning, two concave holes 7 can be formed in the rotary rod 5, and the two concave holes 7 are arranged at 180 degrees, so that the rotary rod can be ensured to accept balance.

With this result, the knob must be rotated continuously, so that the depth of the recess must not be too great, as otherwise jamming is likely to occur, so that the depth of the recess is preferably less than one third of the radius of the ball 9. Therefore, the balls can slide out of the grooves only by applying force slightly, and meanwhile, the ball guide grooves are formed in one side of the groove in the rotating direction, so that the balls can roll out of the grooves conveniently, but the depth of the grooves cannot be too deep, and the situation that the balls can slide out of the grooves directly can occur.
