Description

[Detailed Description of the Invention] The present invention relates to a rotary switch.

Conventional rotary switches take out a desired output by changing the setting position by rotating the switch, and the output output remains unchanged at the same setting position regardless of the direction of the rotation operation. Further, in this type of rotary switch, pulses are sometimes generated at the time of switching to perform various controls, and it would be convenient if the pulse could be selected depending on the direction of rotation operation.
For this purpose, it is desirable that the output of the rotary switch can be taken out separately depending on the direction of rotation.

The present invention has been proposed in view of this point, and is designed so that the output of the rotary switch can be taken out from different output sections even if the switch is in the same setting position, depending on the direction of rotation of the rotary switch.

The present invention will be explained below with reference to the drawings.

FIG. 1 is a partially enlarged view showing one embodiment of the present invention;
FIG. 2 is a plan view of the same embodiment, and FIG. 3 is an equivalent electric circuit diagram of the same embodiment. Note that the same numbers in FIGS. 1 to 3 correspond to each other.

In FIG. 1, reference numeral 1 denotes an insulating substrate, which includes a first annular strip terminal 2 made of a single conductive plate, a second annular strip terminal 3 smaller than the terminal 2, and an annular ring larger than the terminal 2 which is individually insulated. Group of multiple terminals 5
is located. A shaft 4 is provided at the center of the ring formed by the strip terminals 2, 3 and the terminal group 5. One end of a first switch member 9 is fixed to this shaft 4. In the switch member 9, the contact 6 in contact with the strip terminal 2 and the contact 7 in contact with the strip terminal 3 are holes 10, and the contact 8 in contact with one terminal of the terminal group 5 (this terminal is made of a conductive piece, for example) is an insulating member. 11 and 12 are insulated from contacts 6 and 7, respectively. Further, a groove portion 13 is provided at the end of the hole 10 on the free end side of the switch member 9,
In this groove 13, a second
A heart-shaped conductor 14 forming a switch is movably attached. One end of a rod-shaped arm member 16 is also fixed to the shaft 4, and the free end of this arm member 16 is loosely fitted to the conductor 14. When the arm member 16 is rotated, for example, in the direction of arrow A, the free end of the arm member 16 touches the conductor 1.
4 is energized to bring contacts 6 and 8 into conduction. When arm member 16 is rotated in the direction of arrow B, conductor 14 similarly brings contacts 7 and 8 into a conductive state.

FIG. 2 is a top view of this situation, and FIG. 3 is an electrical equivalent circuit. Reference numerals 20 and 21 are output lead-out portions of the strip terminals 2 and 3, and outputs are selectively taken out depending on the direction of rotation of the rotary switch.

As explained above, according to the present invention, the output of the rotary switch can be taken out from separate output terminals by selecting the direction of the rotation operation.
