For this purpose, the gap between the switch button and the surface of the front case, and between the back surface of the front case and the button holding receptacle must be too large, or conversely, it will be undesirable if the clearance becomes a tightening allowance. However, in a switch configured as above, the inner dimension of the locking protrusion l ₁ of the switch button, the thickness dimension of the front case
It is very difficult to control the dimensions of the above-mentioned gap more uniformly due to the variations in dimensions l ₂ and button holding thickness dimension l ₃ . In other words,
In order to make this gap uniform, it is necessary to reduce the number of parts that make up the gap.

への組込を行う。 The size of the switch hole in the front case is such that the width of the holding part can be inserted, so insert the holding part of the switch button into the switch hole from the outside of the front case as shown in Figure 6. When the button spring leg is inserted and pressed in the direction of the arrow, the button spring leg will fall inward due to the slope of the locking protrusion, and the switch button will be set as shown in Figures 3 to 5. At the same time, the locking protrusion is attracted to the back surface of the front case, and the switch button is slidably locked to the front case. In addition, a sloped part is provided at the side wall entrance of the switch hole to make it easier for the sliding guide protrusion to enter.
A sloped portion is also provided at the lower end of the holding portion to facilitate setting of the holding portion into the front case. In addition, the maximum width l ₁₃ of the holding part width of this invention is the switch hole width l ₁₄
Because it is larger, insert the holding receiver in the diagonal direction of the switch hole until it reaches the narrow part of the holding receiver that has a width _l15 narrower than the switch hole width _l14 , then insert the switch button parallel to the front case. Return it and incorporate it into the front case.

本考案は以上の様に構成されているが、本考案
の利点は次の通りである。 Although the present invention is constructed as described above, the advantages of the present invention are as follows.

ラツキよりはるかにすきま管理は容易になり、
スイツチボタンの摺動特性は向上する。(1) In conventional switches, the switch button was separated from the button holder, but in the switch button of this invention, the operation button part and the holder part are integrated, so the switch button and the front part are separated. The uniformity of the sliding clearance of the case is determined by the dimensional variations in only two parts: the locking protrusion of the switch button, the inner dimension l ₁₁ , and the front case thickness l ₁₂ , so the dimensional variations of the three parts in the conventional example are Gap management becomes much easier,
The sliding characteristics of the switch button are improved.

(2) 操作ボタン部〓〓と保持受部が一体になつて

易にできるという実用的メリツトをもたらす。(5) The holding part of the switch button is integrally formed with the operation button part so that it has a substantially L-shaped cross section, so it can be extended to the inner surface of the side wall of the case, and the width direction dimension of the holding part can be adjusted. If you want to provide a wide click part or switch member engaging part, the maximum width of the holding receiving part _l13 is the width of the switch hole 〓〓 mentioned above.
l Even if the size is larger than ₁₄ , the holding part can be inserted into the switch hole by tilting it diagonally to the switch hole. Since the switch button can be returned to be parallel to the side wall of the case, and the switch button can be completely set on the side wall of the case, it is possible to widen the width of the aforementioned holding part and sufficiently meet the required dimensions of the click part and the switch member engaging part. This has the practical advantage of being easy to assemble.
