Description

[Detailed description of the invention] The present invention is an improvement of a type of slide switch in which a movable contact can be switched to multiple positions relative to a fixed contact by sliding an operating member.
This relates to improvements in the slide structure.

This type of slide switch is widely used in various types of equipment, but it is actually difficult to provide a large moderation effect when operating the slide, so a conventional ball-type moderation mechanism is incorporated. If this was done, the width of the slide switch would become unnaturally wide, making it difficult to put it into practical use.

The present invention has been made in view of this problem, and provides a slide switch that can provide a good moderation effect corresponding to each switching position during slide operation without increasing the width of the slide switch. The purpose is to

For this reason, in the present invention, a pair of moderation portions consisting of multiple moderation ridges are formed in parallel on both sides of the slit groove of the case that guides the sliding operation of the operation member, and at the same time, a pair of moderation sections are formed in parallel to each other on both sides of the slit groove of the case that guides the sliding operation of the operation member. An indenter member is provided on the slide block so as to straddle the operating member and has a pair of peaks that can be dropped between adjacent moderation peaks in the sliding direction, and is held against the moderation part so that the indentation can be released freely. A spring compressed between the supporting movable contact member presses the peak of the indenter member against the moderation section, and when switching the operating member, moderation is applied between the indenter member and the pair of moderation sections for each switching position. It is characterized by the fact that

Hereinafter, the present invention will be explained in more detail based on the illustrated embodiments.

In the drawing, 1 is a rectangular parallelepiped-shaped synthetic resin case that is longer in the longitudinal direction than the width, 2 is a locking protrusion 3 protruding from a side surface 2a along the longitudinal direction,
..., 3 is a plate-shaped base made of an insulating material that engages and locks the locking holes 4, ..., 4 provided in the lower part of the side wall of the case 1 when the base 2 is fitted with the case 1. On the upper surface 2b, a pair of left and right fixed contacts 5, 5', 6,
6' and linear central fixed contacts 7, 8, 9 along the longitudinal center line are fixed, and these fixed contacts 5, 5', 6, 6', 7, 8, 9, A movable contact member 1 having left and right contact portions 10a, 10b and a central contact portion 10c provided at the apex of an isosceles triangle with respect to the left and right contact portions 10a, 10b.
0, making up a total of four switch switching positions.

Reference numeral 11 denotes a slide block for retaining the movable contact member 10 downwardly biased by a spring 12 so that the movable contact member 10 is constantly brought into sliding contact with the fixed contact so as not to be relatively movable in the sliding direction; and 13 is a slide block. It is fixed upward in the center of block 11,
This is an operating lever that is assembled into the case 1 and projects outward from a slit groove 14 provided along the longitudinal center line of the upper surface of the case 1 to enable sliding operation.

As shown by dotted lines in the drawing, on the inner surface of the upper wall of the case 1, there is a pair of left and right moderation sections 16, 16 each consisting of a total of three moderation ridges 15 connected in the longitudinal direction with the slit groove 14 in the center. ' is molded at the same time as the case 1 is molded, while an indenter member 17 that constitutes a moderation mechanism between the left and right pair of moderation parts 16, 16' is preliminarily provided in the central thick part of the slide block 11. It is stored in section 18.

The indenter member 17 is preferably a molded product made of an oil-impregnated synthetic resin material, and is provided with a pair of left and right peaks 19, 19' on its upper part. When the slide block 11 is accommodated in the accommodation section 18, the accommodation section 1
A spring projects upward from a pair of left and right retractable grooves 20, 20' that open upward from 8 with the operating lever 13 in between, and is compressed between the movable contact member 10 and the spring receiving hole 17a of the indenter member 17. 21
The left and right moderation portions 16, 1 of the case 1 are
6' so that it can freely retract and retract, and is slidably pressed against it. In addition,
The pair of left and right peaks 19, 19' are the moderating portions 16,
It is formed to an appropriate size so that it can fall into the valley between the adjacent moderation peaks 15, 15 of 16'.

Therefore, when the case 1 is fixed to the base 2 with the indenter member 17, springs 12, 21, and movable contact member 10 assembled to the slide block 11, when the operation lever 13 is slid, the left and right moderation is adjusted. A pair of ridges 1 of the indenter member 17 each time it passes through each of the moderation ridges 15, 15 of the portions 16, 16'.
Moderation is obtained with the fall of 9,19, and therefore,
The operator can confirm the switching operation for each mode, and the movement of the slide block 11 causes the movable contact member 10 to switch between the many fixed contacts 5, 5', and 5' on the base 2 side.
6, 6', 7, 8, and 9, a connection relationship corresponding to the switching position is formed.

In the above embodiment, the moderation portions 16, 16' have three ridges, and a four-position changeover switch has been described, but it goes without saying that the present invention is not limited to this.

As is clear from the above description, the present invention provides a pair of moderation sections on the case side, each consisting of a series of moderation ridges, on both sides of the slit groove parallel to the slit groove, and a pair of moderation sections corresponding to the moderation ridges on the slide block. The present invention provides a slide switch in which a moderation mechanism is constructed by a simple structure in which an indenter member whose peak portion is provided across an operating member is supported so as to be freely retractable and spring-biased in the exit direction.

According to the present invention, the moderation mechanism can be constructed without increasing the width of the switch, and since a pair of moderation mechanisms are constructed with the slit groove and the operating member in between, the operation lever can be operated stably. Moreover, advantages such as a stable and good moderation effect can be obtained.
