The ~ollowing provides an explanation of the present inYention with referen~e to the drawings.
To begin with, as shown in Figs. 1 and 2, the basic constitution (~irst eonstitution) of the present invention consists o~ composing slider 2, made o~ ~luororesin and so ~orth, to be able to slide along guide lb together with -~
movable contacts 2a, made o~ phosphor bronze and so ~orth, along conductors la mounted on insulating base 1 of a slide switch mounted by a known means such as caulking or adhesion. Together with providing two insulating bases 1 in advance in parallel so that their correspondin~ sur~aces on which conductors are ~ormed are in opposition, slider 2, having movable contacts 2a which make sliding contact with each oi said conductors la within the ~ap between said opposirlg sur~aces as shown in Flg. 2, is provided to be able to be moved by guide lb between said two insulatin~ bases 1.
Swinging lever 5 is provided whlch partially engages at engaging point P o~ a pin and so ~orth ln inclined slot 4 ~ormed in its operating piece 3.

- ~23S32 ,.,: h ":~, In addition, together with settlng lts fulcrum O at a pivoting portion 6, such as a pivot shaft, arranged i.~ protruding ~rom a chassis to which the lower portion o-~
;"
insulating base 1 or insulatin~ base 1 is attached in the direction of passage of said slot 4, the orientation o~ said slot 4 is inclined in the direction o~ the gradient, for example downward and to the right, o~ a line connecting said fulcrum O and said engaging point P.
Furthermore, in the above-mentioned embodlment, forming groove 4a ln operating piece 3 instead of slot 4 and engaglng with the pin of s~li.nglng lever 5 produces the same effect. In addition, re-~erence numeral S ln Flg. 2 indicates a spring that enables movable contacts 2a to make elastic contact with conductors la.
. ~ ':
In addition, as shown in Figs. 4 and 5, a second constitution of the present invention may be carried out by having slider 2 protrude ~rom the gap o~ the lower side of opposing insulatlng bases 1, arran~ing operatlng piece 3 attached to this protrudlng portlon 2b to turn in the shape . ` ~-~

Whereupon, sinee operating piece 3 does not largely ;
protrude beyond the periphery of base 1, there are no longer any protruding members resulting in a compact and streamline appearance.

In addition, as shown in Flg. 5, two opposing movable contacts 2a, equipped on both surfaces of slider 2, may be composed so as to respectively make elastic contact with each o~ ~ixed conductors la, each opposed with a single common spring S arran~ed within a slider hole between each contact.
~ ~J~ }
In addition, as shown :in Figs. 6 and 7, the present invention ma~ also be carried out by composing such that sllder 2 protrudeæ ~rom the lower side o~ insulating base 1, and slides along guide lb, arranging operating piece 3, ,. - 10 -2 1 2 3 ~ 3 2 ,,"~,, ... .

Swinging lever 5, having fulerum O on a chassis to whlch ls attached the lower portion o~ base 1 or insulating base 1, engages at engaging point P in inclined slot 4 (or groove 4a) o~ said operating piece 3.
Whereupon, since operating piece 3 does not largely protrude beyond the periphery o~ base 1, there are no longer any protruding members resulting in a compact and streamline appearance.
:: ~
In addition, slider 2 may also be made to protrude from the upper side o~ insulating base 1 as shown in Fig. 7.
The constitution o~ the present invention is as has been described above. The ~ollowing provides a detailed description o~ an example of its use.
In the present invention, together with two insulating bases 1 belng provided in parallel so that the corresponding sur~aces on which conductors are ~ormed are in opposition, slider 2, having movable contacts 2a which make sliding i. ,, l ` / o `7 ~ 2 , ,~, .. contact with each of said conductors la within the gap :~ between said opposing sur~aces, is provided to be able to be 'r',J' moved by guide lb between said two insulatln~ bases 1. As a , ~i result, a large number o~ moving contacts on both sur~aces `i .i of slider 2 are able to make sliding contact with ~ixed .
c conductors la.
In addition, together with fulcrum O of swinging lever 5, provided to engage at engaging point P in slot 4 formed in operating piece 3 o~ slider 2, being set at a pivoting portion 6, arranged in the direction o~ passa~e of said slot 4, since the orientation o~ siaid slot 4 or groove 4a is inclined in the direction of the gradient of a line connecting said ~ulcrum O and said engaging point P as shown in Figs. 1 and 6, slider 2 slides to the location of the broken line o~ Figs. 1 and 4 in the direction of the arrangement o~ ~ixed contacts o~ insulating base 1 due to the ~winglng ~orce o~ said swinging lever 5 which engages at engaging polnt P of a pin and 90 ~orth in slot 4 or groove 4a o~ its operating piece 3 as shown with broken lines in Figs. 1 and 6.

However, in care~ully considering sliding w~dth WS o~
the slider, 1~ the angle Evrmed by the llne in the directlon o~ slot 4 or groove 4a in Fig. 3 and the line in the direction o~ movement o~ slider 2 is taken to be ~ , and the width of parallel movement o~ swinging lever 5 is taken to be W, as shown ln Fig. 3, the slldlng width WS o-f the slider becomes~
WS = W/sin .:
Thus, in the case ~ = 45, WS = 1.41421366 x W, thereby demonstratlng an ampli~ication ~actor o~ roughly 1.4.
Furthermore, the ampli~ication ~actor is 2 when ~ =
30, and 2/1.7320508 3 = 1.154 when 0 = 60.
In addition, since movable contacts 2a move by straddling while making sliding contact with a plurality of conductors la during movement o~ the above-mentioned slider 2, the electrlcal continuity between each conductor la can be controlled, thereb~ allowing use as a slide switch.

In addition, slider 2 may also be made to protrude from the upper side o~ insulating base 1 as shown in Fig. 7.
The constitution o~ the present invention is as has been described above. The ~ollowing provides a detailed description o~ an example of its use.
In the present invention, together with two insulating bases 1 belng provided in parallel so that the corresponding sur~aces on which conductors are ~ormed are in opposition, slider 2, having movable contacts 2a which make sliding i. ,, l ` / o `7 ~ 2 , ,~, .. contact with each of said conductors la within the gap :~ between said opposing sur~aces, is provided to be able to be 'r',J' moved by guide lb between said two insulatln~ bases 1.

However, in care~ully considering sliding w~dth WS o~
the slider, 1~ the angle Evrmed by the llne in the directlon o~ slot 4 or groove 4a in Fig. 3 and the line in the direction o~ movement o~ slider 2 is taken to be ~ , and the width of parallel movement o~ swinging lever 5 is taken to be W, as shown ln Fig. 3, the slldlng width WS o-f the slider becomes~
WS = W/sin .:
Thus, in the case ~ = 45, WS = 1.41421366 x W, thereby demonstratlng an ampli~ication ~actor o~ roughly 1.4.
Furthermore, the ampli~ication ~actor is 2 when ~ =
30, and 2/1.7320508 3 = 1.154 when 0 = 60.
In addition, since movable contacts 2a move by straddling while making sliding contact with a plurality of conductors la during movement o~ the above-mentioned slider 2, the electrlcal continuity between each conductor la can be controlled, thereb~ allowing use as a slide switch.

~ormed ln operating piece 3, in pivot support 6 arranged in the direction o~ passage o~ said slot 4, since the orientation o~ said slot 4 is inclined in the direction of the gradient o~ a line which connects sa~d ~ulcrum O and said engaging point P, slider 2 of a sliding control member such as a slide switch is moved while greatly ampli~ying that movement more than swinging width o~ the swinging lever even when uslng a swinging lever which swings at a nearby -~ulcrum 0, thereby o~-~erlng a second advantage o~ enabling portions related to a slidlng control member such as the shi~t lever o~ a so~called automatic transmission automoblle to be compact, lightweight and inexpenslve.
In the inventions as set ~orth in claims 2 and 3, since operating piece 3 does not greatly protrude beyond the periphery o~ base 1, the additional advantage is o~ered o~
enabling the appearance around the base to be compact and streamline.
The invention as set ~orth in claim 4 enables the ad~ustment operation o~ a slidlng-type variable resistor or so-called slide volume to be improved.
