## Background
BACKGROUND
1. Technical Field
The present disclosure relates to a slidable button and an electronic device using the slidable button.
2. Description of Related Art
Usually, an electronic device such as a Digital Versatile Disc (DVD) player has a slidable button to control a working state thereof. That is, the slidable button turns on and turns off the electronic device. However, in manufacturing, it is difficult to assemble the slidable button onto the electronic device without tools.
What is needed, therefore, is an electronic device having a slidable button which can overcome the above-described problems.

DETAILED DESCRIPTION
Referring to FIGS. 1-3, an electronic device 100 in accordance with an exemplary embodiment of the present disclosure is illustrated. The electronic device 100 comprises a casing 10, a printed circuit board 20 received in the casing 10, and a switch module 30 fixed to the casing 10.
The casing 10 is a rectangular hollow body, which is made from aluminum, steel, or alloy, or composite material such as carbon fiber. The casing 10 comprises a rectangular base plate 12, an annular frame 14 extending from a periphery of the base plate 12, and a cover 16 located on the frame 14. The printed circuit board 20 is fixed on the base plate 12 of the casing 10.
An elongated slot 142 is defined in an outer face of the frame 14, for receiving the switch module 30 therein. A through hole 144 is defined in the frame 14, and is located corresponding to a center of the slot 142. A dimension of the through hole 144 is smaller than that of the slot 142. The through hole 144 has a rectangular profile.
The switch module 30 comprises a slidable button 31 movably seated in the slot 142, and a switch member 32 engaging with the slidable button 31. The switch member 32 comprises a main portion 322, and a switch 324 extending outwardly from the main portion 322. The switch member 32 is electrically fixed on the printed circuit board 20 and located adjacent to the through hole 144. The switch 324 is the part of the switch member 32 nearest to the through hole 144, and faces the through hole 144. The switch 324 is able to be slid relative to the main portion 322, for controlling a working state of the electronic device 100. That is, the switch 324 turns on and turns off the electronic device 100.
Referring to FIG. 4 also, the slidable button 31 comprises an upright operating portion 33, a holding portion 34 extending outwardly and horizontally from the operating portion 33, and two elastic arms 36 respectively extending outwardly from two lateral sides of the holding portion 34. The operating portion 33 has a profile like that of the slot 142. The operating portion 33 is received in the slot 142, and able to slide in the slot 142 from one end of the slot 142 to an opposite end of the slot 142.
The holding portion 34 comprises two spaced holding arms 341 respectively protruding outwardly from the operating portion 33, and a main body 342 interconnecting the two holding arms 341. The two holding arms 341 are located respectively at two lateral sides of the main body 342. The two holding arms 341 are symmetrical relative to the main body 342. A distance between the two holding arms 341 is equal to or a little smaller than a width of the switch 324.
Each of the elastic arms 36 comprises a connecting section 361 extending outwardly from an outer lateral face of a corresponding holding arm 341 of the holding portion 34, and a locking section 362 protruding backward from the connecting section 361, i.e. towards the operating portion 33. The connecting section 361 extends from an end portion of the holding arm 341 remote from the operating portion 33. A distal end of the connecting section 361 is flush with corresponding distal ends of the holding arms 341. The connecting section 361 has an end face coplanar with an end face of the holding arm 341 at the distal ends of the connecting section 361 and the holding arm 341. Each locking section 362 is spaced from the operating portion 33 and from the holding portion 34. In other words, the locking sections 362 are separated from the operating portion 33 by two gaps, respectively. The locking section 362 is spaced from the holding portion by a through pore between the locking section 362 and the holding arm 341. The two elastic arms 36 are symmetrical relative to the holding portion 34. A distance between a top face of each locking section 362 and a bottom face of the holding portion 34 is a little larger than a height of the through hole 144. A top end of each locking section 362 is chamfered for facilitating extension through the through hole 144. A top face of the connecting section 361 of each elastic arm 36 is coplanar with a top face of the holding portion 34. A top face of the locking section 362 of each elastic arm 36 is located higher that that of the holding portion 34.
Referring to FIGS. 5-7 also, assembly of the electronic device 100 is as follows. In a process of inserting the slidable button 31 into the through hole 144 of the casing 10, the locking sections 362 are able to be pressed downwardly until they pass though the through hole 144, due to the resilience of the locking sections 362. After the locking sections 362 have passed through the through hole 144, the locking sections 362 resile to abut against an inner face of the frame 14, and a corresponding portion of the frame 14 is sandwiched between the locking sections 362 and the operating portion 33. Meanwhile, the operating portion 33 is received in the slot 142 and abuts against the outer face of the casing 10 at an inmost extremity of the slot 142, whereby the slidable button 31 is slidably engaged in the casing 10. The operating portion 33 is slidably seated into the slot 142. The switch 324 is sandwiched between the two holding arms 341 of the holding portion 34, whereby when the operating portion 33 is slid along the slot 142, the switch 324 follows the movement of the operating portion 33. Thus the switch 324 is able to control the working state of the electronic device 100 via operation of the slidable button 31 by a user.
It is to be understood, however, that even though numerous characteristics and advantages of the present disclosure have been set forth in the foregoing description, together with details of the structures and functions of the disclosure, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
