Detailed Description

Referring to fig. 1-6, an ac speed-regulating switch with a compact structure includes a base 1, a cover plate 2, a reversing mechanism 3, a contact system 4 and a speed-regulating mechanism 5, where the reversing mechanism 3 includes a reversing bar handle 31, a reversing seat 32 and an unlocking switch 33, the reversing bar handle 31 is connected with the reversing seat 32 through a buckle, and the unlocking switch 33 is pressed down to disengage the buckle between the reversing bar handle 31 and the reversing seat 32, so that the reversing bar handle 31 can be taken down from the reversing seat 32.

In order to enable the reversing gear handle 31 to drive the reversing seat 32 to realize reversing, a buckle 321 is arranged on the reversing seat 32, and a buckle groove 311 arranged on the reversing gear handle 31 is matched with the buckle 321.

In order to prevent the unlocking switch 33 from being touched and opened by mistake, a positioning convex part 331 is arranged on the unlocking switch 33 and is matched with the positioning sliding groove 312 of the reversing gear handle 31, and the unlocking switch 33 is rotationally connected with the reversing gear handle 31, so that the unlocking switch 33 can be pressed down by a certain force to complete unlocking.
