Problems solved by technology

The disadvantage of the speed control switch with the above structure is: when the speed control switch needs to be controlled at full speed, it is necessary to close the full speed contact switch K2, and when the full speed contact switch K2 is turned on and off, the switching current is relatively large, which is easy to generate an arc and damage the full speed switch. The contacts of the contact switch K2 make it impossible to achieve full speed even when the full speed contact switch K2 is closed

Embodiment Construction

[0009] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0010] Such as figure 2 As shown, the speed regulating switch of the present invention includes a contact switch K1 and a MOS tube and a single chip microcomputer 1 connecting the contact switch K1 and the MOS tube. The single-chip microcomputer 1 is arranged on the speed-regulating control board 2, and the program is set in the single-chip microcomputer, which can realize the variable speed and on-off of the speed-regulating switch.

[0011] The advantages of the present invention are: using the single-chip microcomputer 1 to control the MOS tube of the electronic component, so as to realize the speed change and on-off of the speed control switch, no arc will be generated during the speed change and on-off process of the switch, and the speed control switch will be prevented from being damaged.

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 [0001] The invention relates to a speed regulating switch. Background technique [0002] Such as figure 1 As shown, the speed control switch structure usually includes a variable speed contact switch K1, a full speed contact switch K2 and a MOS tube (metal-oxide-semiconductor field effect transistor). After the full-speed contact switch K2 is connected in parallel with the MOS tube, it is connected in series with the variable-speed contact switch K1 as a whole. The disadvantage of the speed control switch with the above structure is: when the speed control switch needs to be controlled at full speed, it is necessary to close the full speed contact switch K2, and when the full speed contact switch K2 is turned on and off, the switching current is relatively large, which is easy to generate an arc and damage the full speed switch. The contacts of the contact switch K2 make it impossible to realize full speed even when the full speed contact switch K2 is close...
