Abstract
The invention discloses a speed control switch which can not generate electric arc. The speed control switch comprises a contact switch, an MOS (metal oxide semiconductor) transistor and a single chip which is connected with the contact switch and the MOS transistor. The switch provided by the invention has the advantages that an electronic element, namely the MOS transistor is controlled by virtue of the single chip, thus the speed change and on-off of the speed control switch are realized, no electric arc is generated in the switch speed change and on-off processes, and the speed control switch is prevented from being damaged.
Description
Technical field
The present invention 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, be easy to generate electric arc and damage 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.
Summary of the invention
Technical problem to be solved by this invention 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 solution used in the present invention 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.
Described single-chip microcomputer is arranged on the speed regulating control plate.
The invention has the beneficial effects as follows: 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 speed-regulating switch of the present invention.
Embodiment
Below in conjunction with accompanying drawing, describe specific embodiments of the present invention in detail.
As shown in Figure 2, speed-regulating switch of the present invention 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.
Advantage of the present invention is: utilize single-chip microcomputer 1 control electronic component metal-oxide-semiconductor, thereby realize speed change and the break-make of speed-regulating switch, can not produce electric arc in switch speed change and make and break process, avoid speed-regulating switch to be damaged.
Claims (2)
