Problems solved by technology

[0010] Therefore, the problem that arises is: along with the miniaturization requirement to the whole switch in recent years, the width of the welding terminal is also reducing, so the welding range of the terminal is reduced, and the welding strength of the terminal on the above-mentioned conductive pattern 17a is very low. Difficult to improve

Abstract

To respond to miniaturization needs of a switch as a whole and provide a push-button switch structure which can aim at improvement of soldering strength of a fixed terminal to a conductive pattern. The switch is provided with a housing 1 equipped with a plurality of fixed contacts 2a, 2b, a movable contact 4 housed in the housing 1 in free contact with and separation from the fixed contacts 2a, 2b and fixed terminals 3a, 3b electrically conducted with the fixed contacts 2a, 2b and protruding toward outside of the housing 1. The fixed terminals 3a, 3b are formed in a linear shape parallel along sidewalls of the housing 1, and the sidewalls of the housing 1 opposing the linear fixed terminals 3a, 3b are provided with a notched part 1b each to be estranged from side face parts of the fixed terminals 3a, 3b.

Description

technical field [0001] The present invention relates to a push button switch that makes a movable contact and a fixed contact contact or disconnect by pressing, and particularly relates to the structure of a small push button switch used in portable electronic equipment and the like. Background technique [0002] The structure of the past pushbutton switch is shown in Figure 8 and Figure 9 . Fig. 8 is a longitudinal sectional view of a push button switch, Figure 9 It is a longitudinal sectional view showing the installation state of the push button switch. [0003] Pushbutton switches in the past consisted of the following parts: [0004] Square housing 21, wherein there is a receiving part; central fixed contact 22a and surrounding fixed contact 22b, both of which are arranged in the receiving part of the housing 21; movable contact 24, which is arranged at the central fixed contact 22a and surrounding fixed contact 22b The opposite side; the cover plate 25, which is ar...
