Embodiment Construction

[0029] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

[0030] Such as image 3 As shown, the present invention provides a switch, including a speed regulation circuit, the speed regulation circuit has a speed regulation branch 10 and a full speed branch 30 connected in parallel in sequence, in addition, in order to reduce the full speed branch when the switch is in the full speed state The current of the circuit 10 reduces the temperature of the contact point on the full-speed branch 10. The speed regulation circuit also has a shunt branch 50 connected in parallel with the full-speed branch 30 after the full-speed branch 30 is connected.

[0031] Such as Figure 4 to Figure 7 As shown, as a specific structure, the switch provided by the present invention also includes a moving push rod 20, which moves ...

Abstract

The invention provides a switch comprising a speed regulation loop. The speed regulation loop is provided with a speed regulation branch and a full speed branch, wherein the speed regulation branch and the full speed branch are in parallel connection and are accessed in sequence. The speed regulation loop is further provided with a shunting branch which is in parallel connection with the full speed branch after the full speed branch is accessed. The switch provided in the invention, on the basis of the current speed regulation branch and the full speed branch, is provided with the shunting branch which is in parallel connection with the full speed branch after the full speed branch is accessed, thereby reducing switch contact resistance of the full speed branch when in full speed, reducing heating value when the switch is working at full speed, reducing the loss of the switch, increasing current-carrying capability of the switch, and prolonging the service life of the switch.

Description

technical field [0001] The invention relates to the field of control switches for electric equipment, in particular to a switch. Background technique [0002] Such as figure 1 and figure 2 As shown, the existing switches used in the fields of DC speed regulation, AC speed regulation, DC on-off, AC on-off, with forward and reverse functions, without forward and reverse functions, with brakes, without brakes, etc. , the speed regulating push rod starts to move to the inside, so that the speed regulating bridge plate 1 is first closed, and the speed regulating bridge plate 1 is connected to the speed regulating terminal 2, so that the switch first enters the speed regulating state; the speed regulating push rod continues to move, The full-speed bridge 3 is closed, and the full-speed bridge 3 is connected to the full-speed terminal 4, so that the switch enters the full-speed state. After the switch enters the full-speed state, the current in the loop flows through the contac...
