The opening / closing operation of the on / off switch 10 is restricted by the timer device 11. Both the first and second switch device bodies 1 and 2 have the above-described configuration, and one second external connection terminal 4 and the other third external connection terminal 5 are connected to each other.

The above-mentioned first and second switch device bodies 1 and 2 have an external structure as shown in FIGS. That is, reference numeral 12 in the drawing is a case, and a lid 13 is attached and fixed to the upper portion of the case 12 by attachment fittings 14, 14. An on / off operator 15 for operating the on / off switch 10 and the timer device 11 is partially exposed from the upper opening of the lid 13.

Inside the first and second switch device bodies 1 and 2, as shown in FIGS. 4 and 5, first, second and third external connection terminals 3, 4, and 5 are arranged. It is roughly divided into two parts, a part where the timer device 11 and the like are arranged.

First, the structure of the former parts will be described with reference to FIGS. The first external connection terminal 3 includes a terminal plate 16 forming a peripheral wall and a holding spring 1 arranged inside the terminal plate 16.
7 is formed as a so-called quick-connect terminal for holding the electric wire inserted into the case 12 from the electric wire insertion holes 18, 18. Similarly, the second and third external connection terminals 4 and 5 are also formed as quick-connect terminals. Below these external connection terminals 3, 4, and 5, there is a current transformer 6 as shown in FIG.
As shown in FIGS. 4 and 5, one end 7a of the primary side winding is electrically connected to the first external connection terminal 3 and the other end 7b is electrically connected to the second external connection terminal 4, respectively. There is.

Next, the structure of each portion of the timer device 11 and the like will be described. As shown in FIGS. 5 and 8, the timer device 11 includes a timer main body 20, a main shaft 21 for winding up a mainspring (not shown) in the timer main body 20, and for taking out the returning force of the mainspring as a rotational force, and the main shaft 21. Is rotated to form a set of the timer device 11, a fixed cam 23 and a movable cam 24 attached to the main shaft 21, and a rotary cam rotatably attached to a support shaft 25 to form a peripheral edge of the movable cam 24. The notch hole 26 is formed with a cam crank 28 with which the latch portion 27 can be engaged.
When the movable cam 24 rotates in the same direction as the winding lever 22 rotates in the clockwise direction in FIG. 8, the latch portion 27 of the cam crank 28 comes out of the notch hole 26. A microswitch 10 as an on / off switch is arranged near the timer device 11.
As shown in FIGS. 5 and 7, the opening / closing operation of the micro switch 10 is restricted by the operating projection 29 of the cam crank 28. Although not shown in the figure, the microswitch 10 is electrically connected between the second and third external connection terminals 4 and 5.

A partition plate 30 is provided above the area where the timer device 11, the micro switch 10 and the like are arranged.
On / off operators 15 are arranged on the partition plate 30 as shown in FIG. The on / off operator 15 has a fulcrum shaft 15a extending laterally from the central portion of the bottom contacting the movable spring 31 as shown in FIG. 6, so that the tilting motion around the fulcrum shaft 15a is regulated. There is. Light emitting diodes 9 and 9 mounted on a substrate 32 are mounted in a hollow portion inside the on / off operator 15, as shown in FIG. These light emitting diodes 9, 9 are electrically connected to both ends 8a, 8b of the secondary winding of the current transformer 6. A hood 33 capable of transmitting light from the light emitting diodes 9 is attached to the upper surface of the on / off operator 15.

The above-described timer device 11 and the on / off operator 15 operate in association with each other by the following configuration. That is, the start projection 34 is provided at one end of the bottom of the on / off operator 15.
Are formed. In the figure, reference numeral 35 denotes a holding body which is swingably provided around a support shaft 36 and is urged in the counterclockwise direction in FIG. 8 by a spring 37, and the starter projection 34 moves counterclockwise in the figure. And swings in the clockwise direction. The timer device 1 is provided on the side wall of the holder 35.
A locking step portion 35a capable of locking the first winding lever 22 is formed. That is, when the winding lever 22 rotates clockwise in FIG. 8 and the timer device 11 is set, the tip end of the winding lever 22 is locked as shown in the same figure. The locked state is released when the holding body 35 swings clockwise in FIG. 8 due to the engagement of the starting projection 34. In the figure, 38 is a timer winding piece,
The upper end has a starting projection 34 at the bottom of the on / off operator 15.
While contacting the formation side end, the lower end is the timer device 11
It is provided so as to be in contact with the hoisting lever 22.
Therefore, when the on / off operator 15 tilts clockwise in FIG. 8, the hoisting lever 22 pivots in the clockwise direction in FIG. 8 in conjunction with this, and the timer device 11 is set.

The operation of the switch device having the above configuration will be described.

First, the first and second switch device bodies 1,
The mechanical operation of No. 2 will be described. The on / off operator 15 is shown in FIG.
When tilted clockwise to the state shown in the figure, the hoisting lever 22 connected to the on / off operator 15 via the timer hoisting piece 38 also turns in the clockwise direction in the same figure and the timer device 11 moves. Set. At this time, the holder 35 swings counterclockwise in FIG. 8 by the urging force of the spring 37 to lock and hold the winding lever 22. Further, the cam crank 28 extends from the notch hole 26 of the movable cam 24 to the latch portion 2.
7 escapes, and therefore rotates about the support shaft 25 counterclockwise in FIG. As a result, the micro switch 10 is maintained in the ON state by the operating protrusion 29 of the cam crank 28.
On the contrary, when the on / off operator 15 is tilted counterclockwise in FIG. 8, the starting projection 34 causes the holding body 35 to swing clockwise in FIG. 8 and the locked state of the hoisting lever 22 is released. Then, the timer device 11 operates and the movable cam 24 rotates counterclockwise in FIG. 8, and after a predetermined time, the notch hole 26 and the latch portion 27 of the cam crank 28 are engaged with each other. Thus, the cam crank 28 rotates clockwise in FIG. 8 and the micro switch 10 is turned off. As described above, the first and second switch device bodies 1 and 2 have a so-called delay operation function in which the microswitch 10 is turned off with a delay of a predetermined time from the operation of the on / off operator 15.

Next, the electrical operation of the switch device will be described with reference to FIG. On / off switches 10, 1 as shown
When both the 0s are off, the on / off switch 10 of the first switch device body 1 is turned on to realize the energized state via the electric wire 40. At this time, in each of the first and second switch device bodies 1 and 2, the light emitting diodes 9 and 9 are turned on by the electromotive force induced in the secondary winding 8 of the current transformer 6, and the above energized state is confirmed. You can When the on / off switch 10 of the second switch device body 2 is turned on from the state shown in FIG.
The energized state is realized via 1, and the energized state can be confirmed by turning on the light emitting diodes 9 and 9 as described above. It goes without saying that the energized state is realized even when the on / off switches 10 and 10 of the first and second switch device bodies 1 and 2 are both turned on. Even when both of them are turned on as described above, the current flowing through the primary windings 7, 7 of the current transformers 6, 6 is constant even if only one of them is turned on as described above. The light emitting diodes 9 and 9 can be turned on.

The present invention is not limited to the above-described embodiment, and it goes without saying that various modifications can be made without departing from the gist of the present invention. For example, in the above embodiment, the on-off switch 10 has the a-contact type, but the b-contact type may be applied. With this configuration, it is possible to realize the conductive state with a delay of a predetermined time after the operation of the on / off operator 15.

Further, one of the timer devices 11 and 11 provided in the first or second switch device bodies 1 and 2 may be removed, and the switch device body may have a normal on / off switch configuration. FIG. 9 shows FIG.
Device 11 of the second switch device body 2 in
Is removed and the configuration is constituted by a normal on / off switch 10. According to this embodiment, the delay operation can be performed only by the on operation of the on / off switch 10 in the first switch device body 1, and the delay operation is performed when the on / off switch 10 of the second switch device body 2 is turned on. Immediately without current transformer 6,6
Current is passed through the primary windings 7, 7 of the light emitting diode 9,
9 can be turned on.
