2. Description of the Related Art Among the conventional push switches, the type (hereinafter referred to as a horizontal push type switch) of a type which pushes in a direction parallel to the surface of an attached circuit board is referred to, for example, in FIGS. As shown in FIG. 14, a terminal to be inserted and soldered in a mounting hole of a circuit board (not shown) extends from the main body 5 at right angles to the switch pressing direction. For example, the illustrated push switch with LED has a pair of terminals 1 connected to contacts for the switch.
Then, the pair of terminals 2 for the LED and the pair of mounting terminals 4 integrated with the metal mounting base 3 respectively extend toward the substrate. In particular, a horizontal pressing push switch that performs a pressing operation in a direction parallel to the surface of the circuit board (not shown) is folded so that the pair of terminals 2 extending from the LED 6 in the push button 7 are twisted at a right angle on the side surface of the body portion 5. It is bent so that it can be extended in one direction. In addition, in the main body part 5,
The main body cover 5a is attached to the upper side, and further, on the side surface opposite to the push button 7, the welded portion 8 protruding from the main body portion 5 is fitted into the through hole formed in the metal attachment base 3, and the metal attachment base is attached. 3 and the main body 5 are melted and fixed so as not to come off.
