Although the elastic contact leg 15 for generating the electric field and the terminal 17 for leading out the generated electric signal to the outside have the same configuration as that of the conventional example, the recess 12B at the rear portion thereof.
Inside the pair of fixed contacts 14A, 14
B has a switch terminal 14 connected to the outer periphery of the switch terminal 14
A hole 1 for mounting the L-shaped actuator 18 is provided on the center side which has C and 14D and is in contact with the recess 12B.
2C is provided.

The L-shaped actuator 18 includes a switch section 14.
As shown in FIG. 4, it is made up of two plate-shaped arms 18A and 18B that intersect each other at a substantially right angle, and circular spindles 18C project on both sides of the intersecting portions.

Next, a method of assembling the rotary encoder with a push switch according to the present embodiment having the above-described structure will be described. First, the central fixed contact 14B in the recess 12B for the switch portion 14 at the rear of the mounting substrate 12 is formed. The dome-shaped movable contact 14E is placed on the outer fixed contact 14A so as to cover it, and the dust-proof flexible film 14F is attached to the upper part thereof to assemble the switch unit 14.

Next, the L-shaped actuator 18 is mounted in the hole 12C of the mounting substrate 12, and the method is as follows.
The arm 18A of the actuator 18 is perpendicular to the surface of the mounting substrate 12, and the arm 18B is directed toward the switch portion 14 side.
The support shaft 18C is the enlarged portion 12 at the front end of the hole 12C of the mounting substrate 12.
D (see FIGS. 2 and 3) is inserted into the hole 12C, and as shown by an arrow in FIG.
At the position of hitting E, the entire L-shaped actuator 18 is lightly pushed horizontally toward the switch portion 14 to move the spindle 1
8C is fitted into the recess 12H formed by the bridge 12E and the top wall 12G beyond the projection 12F on the way, and the entire L-shaped actuator 18 is rotatably held about the support shaft 18C. The lower surface of the tip of 18B abuts on the apex of the upper surface of the dome-shaped movable contact 14E of the switch section 14 via the flexible film 14F.

After that, the holding portion 11B on the side of the driving body 11 is inserted into the circular hole 12A on the side of the mounting substrate 12 from below, and the driving body 11 is combined with the mounting substrate 12, whereby the arm at the rear end of the driving body 11 is assembled. The protrusion 11D at the tip of 11C is the above L
The tip end of the arm 18A of the actuator 18 is abutted.

Then, the rotary contact plate 13 is rotatably attached to the column 11A of the driving body 11 and then the operation knob 16 is attached to complete the rotary encoder with a push-on switch.

Next, the operation of the rotary encoder with a push-on switch according to the present embodiment configured as described above will be described.

First, as shown by the arrow J in FIG. 2, by applying a linear force to the operation knob 16 to rotate it, the rotary contact plate 13 rotates about the column 11A of the driving body 11 and the mounting substrate. Conventionally, the radial contact plate 13A on the lower surface of the rotary contact plate 13 is rotatively slid on the elastic contact legs 15 of 12 to generate a pulse signal, and this signal is output to the outside through the terminal 17 to function as a rotary encoder. It has the same configuration as the example.

During this rotation operation, the force in the pushing direction applied to the operation knob 16, that is, the drive body 11, is applied to the dome-shaped movable contact of the switch portion 14 via the arm 11C at the rear end of the drive body 11 and the L-shaped actuator 18. 14E
However, since the elastic operation force of the dome-shaped movable contact 14E is set to be much larger than this force, the switch 14 is not operated by the pushing force at this time.

Next, when a pushing force is applied to the operation knob 16 against the elastic operation force of the dome-shaped movable contact 14E of the switch portion 14 in the direction indicated by the arrow K in FIGS. 2 and 6,
The rotary contact plate 13 and the entire driving body 11 swing in the direction of arrow L around the holding portion 11B of the driving body 11, that is, the circular hole 12A on the side of the mounting substrate 12, and the projection at the tip of the arm 11C at the rear end of the driving body 11. 11D pushes the tip of the arm 18A of the L-shaped actuator 18 to push the L-shaped actuator 18
6 is rotated about the support shaft 18C as indicated by an arrow M in FIG. 6, and the tip of the arm 18B strongly pushes the apex portion of the dome-shaped movable contact 14E of the switch portion 14 downward, whereby the dome-shaped movable contact 14E is As shown in FIG. 6, the reverse operation is performed with a sense of moderation, and the fixed contacts 14A and 14B, that is, the switch terminals 14C and 14D are short-circuited.

When the pushing force applied to the operating knob 16 is removed, the arm 18B of the L-shaped actuator 18 is pushed up by the elastic restoring force of the dome-shaped movable contact 14E, and the driving body 11, the rotary contact plate 13 and the operating knob. 1
6 is pushed back, and the original state of FIGS. 1 and 2 is restored.

The magnitude of the force that pushes the operating knob 16 when the operating knob 16 is pushed varies depending on the elastic restoring force of the dome-shaped movable contact 14E of the switch portion 14 and the rear end of the driving body 11. The position where the arm 11C pushes the arm 18A of the L-shaped actuator 18,
By changing the position at which B presses the dome-shaped movable contact 14E of the switch unit 14, the relationship between the force for pressing the operation knob 16 and the push stroke can be adjusted. As in the present embodiment, By providing the arm 11C at the rear end of 11 and pushing the most tip of the arm 18A of the L-shaped actuator 18 with the projection 11D at the tip thereof, the push stroke can be set to the maximum.
