The angular spacing of transitions between them is minimal (36 °).

Next, another embodiment of the present invention will be described with reference to FIGS. In FIG. 2, reference numeral 1 is a rotary DIP switch. In this switch 1, as shown in FIG. 3, by rotating the knob P, a pointer N formed of a groove provided in the direction of the generatrix of the knob P is set at 16 positions of the scale G (as will be described later). Operation mode position and power off position) "0", "1",
“2”, …………………, “8”, “9”, “A”,
It can be matched with "B", ..., "F". The angular spacing between these 16 positions is 22.5 °. Here, for simplicity, position "1",
"2", ........., "9" are used and the others are not used.

As shown in FIG. 2, the rotary DIP switch 1 includes, for example, four ON / OFF switches SW0 and S0.
W1, SW2, SW3 are provided, one end of each of which is a common terminal C
It is grounded through the OM and the other ends thereof are connected to the output terminals b0, b1, b2, b3, respectively. Then, when the knob P in FIG. 3 is rotated and the pointer N is made to coincide with the positions "1" to "9", the switches SW0 and S0.
W1, SW2, and SW3 are mechanically turned on by the following combination, and the potential of the terminal connected to the turned-on switch becomes the ground potential. It should be noted that the switch ON is represented by 1, and the switch 0 is OFF.

Switch position SW3 SW2 SW1 SW0 1 0 0 0 0 1 2 0 0 1 1 0 3 0 0 1 1 1 4 0 1 0 0 5 5 0 1 1 0 1 6 0 1 1 0 7 7 0 0 1 1 1 8 1 9 0 0 1 0 0 1

Thus, the rotary DIP switch 1
From each terminal b3, b2, b1, b0 of MSB to LSB
Therefore, a 4-bit binary signal is obtained.

In FIG. 2, reference numeral 2 is a relay, which comprises an on / off switch 2S and a coil 2C. Coil 2C
Has one end connected to the power supply E and the other end connected to the output terminal b of the LSB.
Connected to 0. One end of the on / off switch 2S is a power source E
And the other end is connected to the internal power supply line of the electronic device body. In the relay 2, the switch 2S is configured to be turned on when the coil 2C is not energized and turned off when the coil 2C is energized (however, the reverse is also possible).

Thus, the pointer N of the rotary DIP switch 1 is in the positions "1", "3", "5",
When they match “7” and “9”, the switch SW0 is turned on, and the direct current from the power source E flows through the coil 2C of the relay 2, so the switch 2S is turned off and the power source E is connected to the internal power line. Not supplied. Therefore,
"1", "3", "5", "7", and "9" are power-off positions. When the pointer N coincides with the positions "1", "3", "5", "7", "9" of the scale G, the 3-bit binary signals corresponding to the respective positions are supplied to the terminals b3, b2. , B1 is output, but since the power source voltage is not supplied from the power source E to the electronic equipment body through the internal power supply line, it is meaningless to supply such a binary signal to the electronic equipment body.

Further, when the pointer N of the rotary DIP switch 1 coincides with the positions "2", "4", "6", "8", the switch SW0 is turned off, so that the power source E is turned on.
Since a direct current from the power supply E does not flow through the coil 2C of the relay 2, the switch 2S is turned on, and power from the power supply E is supplied to the internal power supply line. Therefore, the positions "2", "4", "6", and "8" are the operation mode positions. Then, when the pointer N coincides with the positions "2", "4", "6", "8" of the scale G, a 3-bit binary signal corresponding to each position is output from the terminals b3, b2, b1. And is supplied to the main body of the electronic device having the power supply line.

Thus, a plurality of operation mode positions "2", "4", "6" in the rotary switch,
The power-off positions “1”, “3”, “5”, “7”, and “9” where the power is turned off are located during “8”. In this case, the angular spacing between the 16 positions will be a minimum of 22.5 ° when they are equal.

The present invention can be applied to, for example, an underwater communication device that transmits an audio signal using ultrasonic waves or a communication device that uses radio waves. In that case, channel switching is performed by a rotary switch. In this case, carrier frequencies of ultrasonic waves and radio waves are switched by switching channels.

According to the first electronic device of the embodiment, a rotary switch is provided, and a plurality of operation mode positions “1”, “2”, ...
.., the power-off position "OFF" for turning off the power supply is provided between "5", so that the electronic device can have a plurality of operation mode positions and has a rotary switch capable of turning off the power. In the above, the angular intervals at which a plurality of operation mode positions transition to the power-off position, and the angular intervals at which the power-off position returns to the original operation mode position or the operation mode position on the opposite side, that is, a plurality of operation mode positions. Moreover, the angular interval of transition between the power-off positions is reduced, and an electronic device having good operability can be obtained.

A plurality of operation mode positions "1", "2", ..., "5" in the rotary switch.
