ANTENNA CHANGEOVER SWITCH, METHOD FOR ASSEMBLING THE SAME, AND METHOD FOR MANUFACTURING SLIDER BLOCK FOR USE THEREIN

摘要

PROBLEM TO BE SOLVED: To provide an antenna changeover switch where a built-in antenna and an external antenna are selectively changed and used and which can be mounted on a circuit board as one component. SOLUTION: In a slider block 30, each connection terminal 13-18 is arranged so that, in a position using the built-in antenna A1, a connection terminal 13 (a connection terminal for common power supply) and a connection terminal 14 (a connection terminal for built-in antenna power supply) are short-circuited by one contact spring 33, and a connection terminal 16 (a common ground connection terminal) and a connection terminal 17 (a ground connection terminal for the built-in antenna) are short-circuited by the other contact spring 33. In the position using the external antenna A2, the connection terminal 13 (the connection terminal for common power supply) and a connection terminal 15 (a connection terminal for external antenna power supply) are short-circuited by one contact spring 33, and the connection terminal 16 (the common ground connection terminal) and a connection terminal 18 (a ground connection terminal for the external antenna) are short-circuited by the other contact spring 33.
