[Embodiment] Next, an embodiment of the two-behavior operation switch device of the present invention will be described. 2 and 3, the shaft 1
Reference numeral 5 denotes an axis for performing a first behavior operation by an axial movement operation of the handle 2 and a second behavior operation by a rotation operation of the handle 2. The notch cam 5 is fixedly attached to the shaft 15 and has an uneven portion on the periphery. The contact cam 6 is fitted with the notch cam 5 and has a recessed portion in the periphery thereof, and rotates together with the notch cam 5 to perform an operation switch operation by the first behavior operation. The disk-shaped male connection cam 8 is fixed to the tip of the shaft 15 and has a protrusion 8a on the periphery. The disc-shaped female connecting cam 7 is provided so as to face the male connecting cam 8,
It has an insertion hole 7a into which the protrusion 8a is inserted, the protrusion 8a is inserted by the first behavior operation, and the operation switch operation is performed by the second behavior operation.

That is, FIG. 1 shows an example of the outer shape of the operation switch according to the present invention. The two-action operation switch is composed of a case 1 of the switch body, a flange 4, a handle 2, and a nameplate 3. The full water standby and the stop operation can be operated by twisting in one behavior operation, and the operation and the vacuum breaking operation can be operated by twisting while pulling in two behavior operation.

FIG. 2 shows the structure of the two-behavior operation switch. The notch cam 5 and the contact cam 6 are for one-motion operation, and the female connection cam 7, the male connection cam 8, the notch cam 9, and the contact cam 10 are for two-motion operation. is there.

In one behavior operation, notch cam 5 and contact cam 6
The male connecting cam 8 and the male connecting cam 8 rotate on the same shaft 15, but the female connecting cam 7, the notch cam 9 and the contact cam 10 do not rotate because they are separate shafts 15a.

Since the handle 2 is pulled in the two-action operation, the female connection cam 7 and the male connection cam 8 are connected, and the notch cam 5, the contact cam 6, the female connection cam 7, the male connection cam 8, the notch cam 9 and the contact cam 10 are connected. Rotate. However, since the contact cam 6 pulls the handle 2, the contact cam 6 is moved out of the contact position and the 1 behavior switch does not operate. Therefore, when the screw is twisted without being pulled, it is twisted to the full water standby or stop position, but is not twisted to the operation or vacuum break position.

FIG. 3 shows a cross-sectional structural view of the connecting portion. When the handle 2 is pulled, the shaft 15 moves to the left and the male connecting cam 8 also moves to the left, so that it is connected to the female connecting cam 7 and subsequently twisted. Then, the notch cam 9 rotates.

FIG. 4 is a detailed structural view of the mechanism section. The notch cam 5, the roller 12, the lever 13, the spring 14, and the shaft 15 constitute an operating mechanism.

FIG. 5 is a detailed structural diagram of the contact portion, in which the movable contact 19 is moved by the connecting cam 6 and the movable rod 18 to contact the fixed contact 16. Reference numeral 17 is a contact spring.

FIG. 6 is a development view of the two-behavior operation switch. Positions B and C can be operated by twisting in one-behavior operation, and positions A and D can be twisted while pulling in two-behavior operation. Can be operated by.

By operating to the position B, the terminal 6
When terminals 1 and 62 are turned on and the position C is operated, terminals 63 and 64 are turned on. The terminals 65 and 66 are turned on by operating (pulling) the position A, and the terminals 67 and 6 are operated by operating (pulling) the position D.
8 turns on. At this time, position A shows operation, position B shows full standby, position C stops, and position D shows vacuum break.

FIG. 7 is a front view of FIG. 6, and FIG. 8 is a structural diagram of a two-behavior operation switch showing another embodiment. The notch cam 5 and the contact cam 6 are for one-motion operation, and the connection cam 22, the notch cam 9 and the contact cam 10 are for two-motion operation.

In one behavior operation, notch cam 5 and contact cam 6
And the connection cam 22 rotate on the same shaft, but the notch cam 9 and the contact cam 10 do not rotate because they are different shafts.

In the 2-behavior operation, since the push button 23 of the handle 2 is pushed, the connection cam 22 and the notch cam 9 are connected, and the notch cam 5, the contact cam 6, the connection cam 22, the notch cam 9 and the contact cam 10 rotate. However, the contact cam 6 is the handle 2
Since the push button 23 of No. 1 is pushed, the switch for the 1-behavior deviates from the contact position and does not operate.

Therefore, when the push button 23 of the handle 2 is twisted without being pushed, it is twisted to the full water standby or stop position, but not to the operation or vacuum breaking position.
