DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a switch structure such as a microswitch and a method for manufacturing the same.

[0002]

2. Description of the Related Art A micro switch having a conventional switch structure has a common terminal (common terminal) 5 as shown in FIG.
0 and a fixed terminal 51 having a normally closed fixed contact 51a
A fixed terminal 52 having a normally open fixed contact 52a;
Movable piece locking portion 53 of first upstanding piece 53 of common terminal 50
A movable piece 54 having a movable contact 54a at the other end, the movable piece 54 having a movable contact 54a at the other end.
And a snap spring 56 locked across the other end of the movable piece 54. The push button 57 is moved up and down to perform switching by the snap operation of the snap spring 56.

[0003]

However, in the above-described conventional switch structure (micro switch), since the movable piece 54 and the snap spring 56 are separate members, the movable piece 54 and the snap spring 56 are separated from each other. There is also a problem that there is a joint A that joins with the spring 56, and since the joint A must be checked at the time of assembly, the production quantity does not increase, and a large-scale automatic assembling machine is required. Was.

When used as a mouse-only switch, the switch is fixed to the board, so that the fixed terminal 51, which is a normally closed terminal, is unnecessary. There is a problem that the mold is complicated to make the parts and the cost of the parts is increased.

Further, when the push button 57 and the cover 58 are separate members, and when the intermediate piece such as the movable piece 54 and the snap spring 56 are fitted to the push button 57 and the cover 58, the intermediate It is necessary to suck the cover 58 and the push button 57 together by the suction means of the assembling machine. for that reason,
There has been a problem that a large-scale automatic assembly machine is required for automation.

In the above-described conventional switch structure,
At the time of assembling the switch, it is necessary to invert the entire switch structure or to invert the member such as the movable piece 54, so that not only large equipment is required, but also it is difficult to assemble a large number of pieces.

The present invention has been made in view of the above problems, and a first object of the present invention is to simplify the insert mold structure and reduce the cost of parts. It is to provide a switch structure.

A second object of the present invention is to complete the switch structure by merely moving at least the movable spring member and the cover with respect to the base in this order toward the base.
