Electronic device switch

An electronic device switch comprising:

• a plurality of switch patterns formed substantially parallel one with another in positions close to a peripheral edge on both surfaces of a circuit board;
• a power source pattern formed on a side surface of the circuit board;
• and
• a terminal having a fixing leg, a connection leg provided in contact with any of the switch patterns in either an ordinal position or an inverted position of the terminal and fixed by clamping the circuit board cooperatively with the fixing leg, and a switch terminal positioned substantially opposed to the power source pattern and electrically connected with the connection leg to be elastically deformed into possible contact with the power source pattern.

An electronic device switch comprising:

• a plurality of switch patterns formed substantially parallel one with another in positions close to a peripheral edge on a surface of a circuit board;
• a power source pattern formed on a side surface of the circuit board;
• and
• a terminal having a plurality of recesses in a terminal housing correspondingly to the switch pattern to insert therein a conductor member, a fixing leg extending from the terminal housing to be fixed by clamping the circuit board, and a switch terminal positioned substantially opposed to the power source pattern and electrically connected with the conductor member inserted in the recess to be elastically deformed into possible contact with the power source pattern.

An electronic device switch comprising:

• a plurality of switch patterns formed in an array form in a position close to a peripheral edge on a surface of a circuit board;
• a power source pattern formed on a back surface of the circuit board;
• conductor parts sandwiching an insulating part, the conductor parts being to be fixed by clamping the circuit board;
• and
• a conductive contact provided on a button to contact both of the conductor parts.
