For example, as shown in FIG. 3, a snap acting switch mechanism 5 is accommodated within the switch case 2. As shown in FIG. That is, the anchor 6 has one end fixed inside the case 2 and the other end drawn out of the case 2 to form the common terminal 7. The lever 8 has one end pivotally connected to the anchor 6, and
The other end is in contact with a plunger 9 that is slidably attached to the case 2. The movable spring 10 connects one end of the tension member 11 to the lever 8 and the compression member 12
One end of each is engaged with the anchor 6.
The fixed terminals 13 and 14 are fixed to the case 2, and form a normally closed terminal 15 and a normally open terminal 16 on the outside thereof. A normally closed fixed contact 17 and a normally open fixed contact 18 are provided in the portions of the fixed terminals 13 and 14 located inside the case 2 to face each other. Both fixed contacts 1 are attached to the free end of the movable spring 10.
A movable contact 19 is provided which selectively contacts 7,18.

クタ２３に接続するようにされている。 A rectifier 20 consisting of, for example, a full-wave rectifier is housed in the light emitting case 3, and one of its input terminals is drawn out of the case 3 and connected to a power source (not shown).
connected to one terminal of the Also, inside the case 3 is a light emitting element 21 consisting of, for example, a light emitting diode.
is accommodated, and this is connected to the rectifier 2 via a resistor 22 etc.
0 output terminals. The other input terminal of the rectifier 20 is connected to, for example, the normally open terminal 16 of the switch mechanism 5, and the common terminal 7 of the switch mechanism 5 is connected to the other terminal of the power supply. Furthermore, an optical connector 23 is fixed to the light emitting case 3,
One end thereof is optically connected to the light emitting element 21, and the other end extends outside the case 3. A coupling ring 25 is provided at one end of the optical cable 24,
This coupling is adapted to connect the optical cable 24 to the connector 23 by screwing into the threaded portion 22 of the connector with one end of the optical cable 24 inserted into the connector 23.

強いアダプタを得ることができる利点がある。 As described above, in this device, the snap actuating switch mechanism 5 and the light emitting element 21 that selectively emits light by opening and closing the switch mechanism are housed in substantially one housing 1, so that the influence of noise is extremely low. Although it is mechanical, it has very good responsiveness to external forces, and since light is used for signal transmission, it has the advantage of being able to provide an adapter with strong environmental resistance.
