Abstract
The utility model discloses a speed regulating switch which cannot generate an electric arc and comprises a contact switch, a MOS (Metal Oxide Semiconductor) tube and a single-chip; and the single-chip is connected with the contact switch and the MOS tube. The speed regulating switch has the advantages that the single-chip is adopted for controlling an electronic element, the MOS tube, so as to realize the speed change and on-off of the speed regulating switch, and no electric arc is generated in speed change and on-off process, so that the speed regulating switch is prevented from being damaged.
Description
Technical field
The utility model relates to a kind of speed-regulating switch.
Background technology
As shown in Figure 1, the speed-regulating switch structure generally includes speed change contact switch K1, full speed contact switch K2 and metal-oxide-semiconductor (metal-oxide-semiconductor field effect transistor).Integral body is connected with speed change contact switch K1 after contact switch K2 and the metal-oxide-semiconductor parallel connection at full speed.The shortcoming of the speed-regulating switch of said structure is: when the needs speed-regulating switch is controlled to be at full speed; Contact switch K2 at full speed need close; And at full speed during contact switch K2 break-make; Switching current is bigger, is easy to generate electric arc and damages the at full speed contact of contact switch K2, even also can't realize at full speed when causing closing at full speed contact switch K2.
The utility model content
The utility model technical problem to be solved is: a kind of speed-regulating switch that can not produce electric arc is provided.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of speed-regulating switch comprises the single-chip microcomputer of contact switch and metal-oxide-semiconductor and connecting terminal switch and metal-oxide-semiconductor.
Said single-chip microcomputer is arranged on the speed regulating control plate.
The beneficial effect of the utility model is: utilize Single-chip Controlling electronic component metal-oxide-semiconductor, thereby realize the speed change and the break-make of speed-regulating switch, in switch speed change and make and break process, can not produce electric arc, avoid speed-regulating switch to be damaged.
Description of drawings
Fig. 1 is the circuit block diagram of speed-regulating switch in the background technology;
Fig. 2 is the circuit diagram of the utility model speed-regulating switch.
Embodiment
Below in conjunction with accompanying drawing, describe the specific embodiments of the utility model in detail.
As shown in Figure 2, the described speed-regulating switch of the utility model comprises the single-chip microcomputer 1 of contact switch K1 and metal-oxide-semiconductor and connecting terminal K switch 1 and metal-oxide-semiconductor.Single-chip microcomputer 1 is arranged on the speed regulating control plate 2, and configures program in the single-chip microcomputer, can realize the speed change and the break-make of speed-regulating switch.
The utility model has the advantages that: utilize single-chip microcomputer 1 control electronic component metal-oxide-semiconductor, thereby realize the speed change and the break-make of speed-regulating switch, in switch speed change and make and break process, can not produce electric arc, avoid speed-regulating switch to be damaged.
Claims (2)
1. speed-regulating switch comprises contact switch and metal-oxide-semiconductor, it is characterized in that: the single-chip microcomputer that also comprises connecting terminal switch and metal-oxide-semiconductor.
2. speed-regulating switch according to claim 1 is characterized in that: said single-chip microcomputer is arranged on the speed regulating control plate.
