Description

[Detailed Description of the Invention] The present invention relates to an improvement of a switch, and its purpose is to provide a switch with a simple structure and an indicator lamp that can indicate the position of the switch in the dark.

The present invention will be described below with reference to one embodiment of the present invention. 1 is a switch body consisting of a switch case 2 and a switch cover 3; 4 is a mounting frame for fixing the switch body 1;
Reference numeral 5 designates one terminal device, and this terminal device 5 includes a contact piece 7 having a spring bearing protrusion 6, a terminal portion 9 provided with terminal pieces 8, 8, a locking piece 10.10, and a contact piece 11.11. A lock release button 14 has contact pieces 13, 13 that engage with and displace the lock piece 10. It will be installed.

15 is the other terminal device, and this terminal device 15 is connected to the contact 16.
A load terminal section 1 provided with a contact piece 17 and a terminal piece 18 having
9, a connecting terminal part 23 having a contact piece 21 having a contact point 20 and a terminal piece 22, a locking spring 26 having a locking piece 24 and a contact piece 25, and a chain having a locking piece 27 and a contact piece 25. A lock spring 29, an abutment piece 30 that engages with and displaces the lock piece 24 of the lock spring 26, and a lock piece 27 of the lock spring 29.
The lock release button 32 is mounted on the other side of the switch case 2 and has an abutment piece 31 that engages with and displaces the lock release button 32.

Reference numeral 33 denotes an operation button, which is swingably attached to the switch cover 3 by a support shaft 34, and is provided with a display window 36 for a display lamp 35.

Reference numeral 37 denotes a wiring board, and this wiring board 37 is attached to the lower surface of the operation button 33, and has a contactor 38 that constantly contacts the load terminal section 19 regardless of the swinging position of the operation button 33, and a contactor that contacts the connection terminal section 23. The end portion of the child 39 is fixed, and the load terminal portion 1
An indicator lamp 35 is connected in series between the end of the terminal 9 and the connection terminal section 23 via a resistor 40 .

41 is a movable contact piece, and this movable contact piece 41 has a support piece 42 supported by the spring support protrusion 6 of the terminal portion 9, and a contactor 44 having a load contact 43 that contacts the contact 16 of the load terminal portion 19. , and a contact 46 having a connection contact 45 that contacts the contact 20 of the connection terminal portion 23 are integrally formed in a U-shape.

Reference numeral 47 denotes a swing spring, one end of which engages with the movable contact piece 41, and the other end of which is locked into the engagement hole 48 of the operation button 33.

The switch of the present invention has the above-mentioned configuration, and to explain an embodiment in which this switch is used as a three-way switch for blinking stairway lighting, for example, Fig. 3 is a wiring diagram when lighting fixture 49 is turned on; The contact 16 of the load terminal section 19 of the switch A and the load contact 43 of the movable contact piece 41 are in contact with each other,
Since the contact 16 of the load terminal portion 19 of the other switch B is in contact with the load contact 43 of the movable contact piece 41, the lighting fixture 49 lights up.

At this time, the indicator lamp 35 connected between the load terminal section 19 and the connection terminal section 23 is in an off state.

Next, one of the switches A, for example, is activated to reverse the movable contact piece 41 and bring the contact 20 of the connection terminal portion 23 into contact with the connection contact 45 of the movable contact piece 41, as shown in FIG. 49 is turned on and it becomes dark, the indicator lamp 35 lights up both switch A and switch B, and the indicator lamp 39 indicates the location of the switch.

As mentioned above, the present invention can be even more effective when used in a three-way switch for stairway lighting. The location can be clearly indicated, and in particular, the contact pieces 38 and 39 are bent in the handle above the wiring board 37 and extended below the wiring board 37 to contact the load terminals 19 and 23, respectively. The structure and installation of the contact are extremely simple, and the length of the contact can be made longer, making it easier to bend, so it can always be in constant contact with the load terminal, and there is no discomfort when operating the handle. It never happens.

The present invention is practical and convenient in these respects.
