How to attach terminal for rotary switch

(Industrial use field)

The present invention relates to a method for attaching a plurality of rotary switch terminals attached to a switch base of a rotary switch such as an ignition switch for an automobile.

(Prior art)

In this kind of automotive ignition switch, the ignition key is inserted into the key hole of the ignition switch, and the rotation of the ignition key rotates the rotator in the ignition switch so that the movable contact (movable contact) And is rotated integrally with the electron. In addition, it is common that the electrical contact between the plurality of point-like stationary contacts formed on the switch base is switched by the movable contact by the rotation operation. Fig. 8 (a) shows this switch base.

8 (a), reference numeral 1 denotes a base made of resin (resin) of an ignition switch (not shown). The switch base 1 has a cylindrical portion 1a and one end of the cylindrical portion 1a And a wall portion 1b which closes. In Figs. 9 and 10, 2 is a switch terminal.

The switch terminal 2 has a terminal body 3 and a contact member 4 as a fixed contact, as shown in Figs. In addition, the terminal body 3 has a substantially L shape formed by a plate-like attachment portion 3a and a leg portion 3b.
