Problems solved by technology

results, such as Figure 15 As shown in (a), the upper end of the coil spring 13 is biased on one side, and since the spring load bias is applied to one side of the operation panel 5, the operating load of the operating handle 5 is reduced during the ON operation and the OFF operation. There is a big difference, and there is a problem that the tactile feeling at the time of operation deteriorates

Embodiment 1

[0078] Below, according to Figure 1 to Figure 5 Example 1 of the present invention will be described. The switch A of this implementation form is a toggle switch, and its body 1 is as figure 2 and image 3 As shown, it is composed of a synthetic resin main body 2 with an open front and a synthetic resin cover 3 covering the front surface of the main body 2. The main body 2 and the cover 3 pass through a pair of metal assembly frames 4, 4. combine together. Alternatively, the switch A, such as Figure 4 As shown, it is embedded in the embedding hole provided in the structure such as the wall surface of the mounting frame 60 (refer to JIS C 8375) mounted on the large square serial wiring tool. The formation dimension of the body 1 (this dimension is referred to as size of one assembly), so that the length direction of the body 1 is approximately perpendicular to the length direction of the installation opening 61 of the installation frame 60, and three can be installed sid...

Embodiment 2

[0097] Now, refer to Image 6 and Figure 7 Example 2 of the present invention will be described. In addition, since the basic structure of the switch is the same as that of the first embodiment, the same symbols are used for the common structures and their descriptions are omitted, and only the features constituting the characteristics of this embodiment will be described.

[0098] In this embodiment, for the switch of Embodiment 1, instead of providing the wire terminal accommodating groove 55 on the bottom surface of the cylindrical protrusion 53 into which the wire terminal 17a enters, the inner wall of the cylindrical protrusion 53 is protrudingly provided with a plate The spring 13 contacts and presses the coil spring 13 against the inner wall on the opposite side, and the rib 56 of the upper end of the coil spring 13 is forcibly moved in such a way that the upper end of the coil spring 13 is inserted approximately perpendicularly to the bottom surface of the cylindrica...

Embodiment 3

[0102] Below, refer to Figure 8 and Figure 9 Embodiment 3 of the present invention will be described. Furthermore, since the basic structure of the switch is the same as that of Embodiment 2, the same symbols are used for the common structures and their descriptions are omitted, and only the structures constituting the characteristics of the present invention will be described.

[0103] In Embodiment 2, on the inner wall of the cylindrical protrusion 53, the rib 56 is formed from the bottom to the edge of the opening. In contrast, in this embodiment, the rib 56 develops from the opening side to the bottom side, thus forming a cylindrical The inclined surface 57 whose inner wall protrusion amount of the protrusion 53 is increased widens the opening of the cylindrical protrusion 53 compared with the case where the rib 56 is formed to the edge of the opening, thereby improving the workability of inserting the coil spring 13 .

Abstract

The present invention provides a switch with a small difference in operating load at the time of ON / OFF. The operating handle (5) remains freely rotatable relative to the body of the switch. A cylindrical protrusion (53) protrudes from the back of the operating handle (5), and a coil spring (13) that applies a reverse rotational force to the contact point mechanism is inserted into the cylindrical protrusion (53). And, insert the wire terminal (17a) of impedance (17) in the cylindrical protrusion (53) through the longitudinal groove not shown in the figure, and arrange on the bottom surface of cylindrical protrusion (53), and coil spring (13) ) The upper ends are electrically connected and mechanically connected. Here, a lead terminal accommodating groove (55) into which the lead terminal (17a) can enter is formed on the bottom surface of the cylindrical protrusion (53). The elastic force of the coil spring (13) will not bias the operating handle (5), which can reduce the operating load difference during on / off operation, and the tactile feeling during operation is good.

Description

technical field [0001] The present invention relates to a switch. Background technique [0002] In the past, there have been offers such as Figure 15 and Figure 16 Switch A of the structure shown. A body 1 of the switch A is composed of a substantially box-shaped synthetic resin main body 2 with an open front and a synthetic resin cover 3 covering the front surface of the main body 2 . [0003] The interior of the main body 2 is divided into a plurality of areas by a partition wall, and the terminal accommodation chambers 22, 22 for accommodating the terminals connected to the external electric wires are arranged on both sides, and the contact accommodation chamber 23 for accommodating the contact mechanism is arranged in the center. [0004] Terminals of a so-called connection terminal structure composed of terminal plates 6 , 7 , each pair of lock springs 8 , and release buttons 9 are housed in the terminal housing chambers 22 , 22 , respectively. [0005] An extensio...
