Problems solved by technology

Due to the heating applied to the assembled body during the brazing, in the above-mentioned prior art, the elastic force of the elastic movable contact may be weakened due to heat, resulting in a decrease in the elastic force of the movable contact. , it is difficult to ensure the required contact pressure
In addition, heating the above-mentioned assembly in a state where the elastic force of the movable contact is applied to the case via the fixed contact may cause deformation on the case.
In this way, in the prior art, there is also a problem that the reliability of the switch device is easily reduced when the switch device is mounted on the circuit board by soldering.

no. 8 Embodiment approach

[0120] In the eighth embodiment, the hemispherical convex portion 46c is formed on the holding member 46, and the inclined surface 45b joined to the hemispherical convex portion 46c is formed on the drive member 45, but the reverse may also be used. A hemispherical convex portion is formed on the driving member 45 , and an inclined surface engaged with the hemispherical convex portion is formed on the holding member 46 .

[0121] [Structure of the ninth embodiment]

[0122] Fig. 22 is a side view showing main parts of a ninth embodiment of the present invention. In this ninth embodiment, similarly to the fourth embodiment, the cover member 49 covering the storage portion 48a of the not-shown case has a curved surface that protrudes toward the second fixed contact side disposed in the not-shown case. The protrusion 49 a and the operating body 50 that slides the movable contact 51 are formed of a member having an inclined surface 50 a that can come into contact with the protrus...

no. 9 Embodiment approach

[0124] Also in the ninth embodiment configured in this way, when the operating body 50 is slid to bend the coil spring 53 , the inclined surface 50 a of the operating body 50 engages with the protrusion 49 a of the cover member 49 , and the coil spring strengthens by being compressed. The force generated by the elastic force of the spring 53 holds the movable contact 51 on the operating body 50 toward the second not-shown side of the housing through the abutment between the protrusion 49 a of the cover member 49 and the inclined surface 50 a of the operating body 50 . The fixed contact side is pressed to obtain almost the same effect as that of the first embodiment. In addition, when returning the operating body 50 to the initial position, the holding state of the operating body 50 by the snap mechanism 52 is released, and the operating body 50 can be returned to the initial position.

Abstract

In a voltage generating circuit for a semiconductor memory device, each of a plurality of reset signal generators individually generates a reset signal in response to one of a plurality of external source voltages. The plurality of external source voltages have different voltage levels. An output voltage generator generates a plurality of output voltages by independently driving each of the plurality of external source voltages in response to a corresponding one of the plurality of reset signals. The output voltage generator outputs the plurality of output voltages through a common output terminal.

Description

technical field [0001] The present invention relates to a switch device effectively used for a key lock of a mobile phone or the like. Background technique [0002] As such prior art, there is a technique described in Patent Document 1. This patent document 1 discloses a self-resetting slide switch, that is, a switch device, which includes: a frame composed of a case and a cover member covering the case; In the storage part of the body, the elastic movable piece that can contact the fixed contact is the elastic movable contact; and the sliding body that holds the movable contact and can slide in one direction is the operating body. The accommodating part of the contact has an opening at the top and is made of synthetic resin. In addition, an elastic member that is a coil spring that is arranged in the housing portion of the housing to return the operating body to its initial position is provided, and the operating body is slid against the elastic force of the elastic memb...
