ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates a dial programming switch comprises, especially, a switch structure which can be connected to a pin bank connector, and manufactured easily. Thus, the cost is reduced greatly.
2. Description of the Prior Art
The prior art dial programming switch includes a seat, an upper cover, a plurality of push button, and terminal sets. The terminal sets include a first terminal and a second terminal. Furthermore, a conductive terminal is installed on the push button. By the pushing of the push button, the conductive terminal may selectively control the conduction of the first terminal and second terminal for determining the ON and OFF states of a switch. Such kinds of patent can refer to Taiwan Patent Publication Nos. 291180, 311730, 308350, etc.
However, in the prior art dial programming switch, each push button needs to assemble with a conductive terminal with much working time and hours. Thus the manufacturing process is complex so that the cost is high. Moreover, the prior art dial programming switch has terminal sets which are connected with other objects by welding. Thus, the use thereof is very inconvenient.
SUMMARY OF THE INVENTION
Accordingly, the primary object of present invention is to provide a dial programming switch comprises, especially, a switch structure which can be connected to the pin bank connector, comprises a seat, an upper cover, a plurality of push buttons and terminals. In the present invention, by the integrally formed first contact portion of the first terminal and the convex portion to move upwards and downwards. The contact between the first contact portion of the first terminal and the second contact portion of the second terminal is controlled so as to select the switch to be in an OFF or ON state. The first terminal, second terminal, and convex portion are integrally formed. It can be manufactured easily. Thus, the cost is reduced greatly. The conductive terminal assembled in a push button for controlling the conduction of the first terminal and the second terminal as that in the prior art technology need not be used in the present invention.
The various objects and advantages of the present invention will be more readily understood from the following detailed description when read in conjunction with the appended drawing.
