2. Description of the Related Art Seesaw switches have been used as main power switches used in portable electronic information devices and the like, but these switches are liable to malfunction when external force acts on them. The slide switch has been used in recent years because it causes a trigger and there is a risk that software or the like will be destroyed if the power is suddenly turned off in an information device or the like.

In particular, Japanese Patent Publication No. 1-17779 discloses a slide switch, in which the slide switch is held in a locked state at an operating position of the switch in order to prevent an unexpected malfunction. A slide switch with a simple locking mechanism is used.

That is, the lock mechanism provided in this type of slide switch has a left and right side at the bottom of the switch case.
A set of fixed terminals is projected and arranged in series on the terminal board, and a slider with a protrusion at the center of the upper part of these fixed terminals is slidable inside the switch case. A recess for receiving the protrusion of the slider is formed on the back surface of the top plate of the switch case.

Further, immediately below the protrusion of the slider, a recess space is formed in the bottom corresponding to the protrusion, and a movable contact piece is formed in this space via a compression spring with respect to the plurality of fixed terminals. It is stored so that it can be turned on and off when it moves with the slider.

Therefore, when the slider is short-circuited due to the movement of the slider, the protrusions of the slider are locked in the recesses of the switch case to be in a stationary state.

[0007]

However, in the slide switch provided with this lock mechanism, the protrusion of the slider and the engaging portion formed on the back surface of the top plate of the switch case that engages with the slider are mutually It is formed in a triangular shape in cross section, and the protrusion of the slider is always pressed by the compression spring, and when it is locked, it is confirmed by a click feeling, but when the protrusion is separated from the recess, Is configured such that the protrusion of the slider crosses over the concave portion and separates only by the acting force due to the lateral movement of the slider, so that there is a drawback that an excessive force is required to operate the slide switch. However, the switch is dedicated, complicated and large in size, and there is a difficulty that does not accompany miniaturization of information equipment.

Therefore, an object of the present invention is to improve the operability of a slide switch having a lock mechanism and to generalize the main power switch used for the slide switch, and at the same time, to realize the downsizing of the slide switch. A slide switch provided with a mechanism is provided.

[0009]

In order to achieve the above object, the present invention provides a long groove in a part of a case body, and at least two notches are symmetrically provided in the long groove, and A center hole is provided and a plurality of claws are provided on the side surface of the center hole, and a holder that is connected to the main power source and inserts and locks the claws is provided, and a spring member is pressed between the slider and the holder. A lock member having a protrusion and a locking rod is interposed so that the pressing protrusion is inserted into the central hole of the slider under the action of the spring member, and the lock member is engaged by pressing the pressing portion. The stop bar engages and disengages with the notch of the long groove.

In this case, the claw portion of the slider is composed of a plurality of locking arms projecting from the side surface of the slider and a locking claw provided at the tip of the locking arm. Is formed on the upper surface of the holder, a groove portion for inserting the locking rod of the lock member is formed on the side edge of the opening, and the plurality of locking claws are formed on the lower surface of the holder. It is preferable that a through hole to be inserted is provided, a locking groove is provided at each side edge of the through hole, and the locking claw inserted through the through hole is locked to the locking groove.

[0011]

In the present invention, since the slide switch is separated from the main power switch, the slide switch can be miniaturized with the lock mechanism incorporated, and at the time of operating the slide switch,
When the slide switch in the locked state is released, it can be performed by pressing the pressing portion protruding from the slider, and the operability can be simplified.
