PROBLEM TO BE SOLVED: To provide a mechanical switching apparatus allowing the user to perform switch operations with the thumb of the hand gripping the switch. SOLUTION: In the switching apparatus, a spring contact piece 91a of a relay fitting 91 faces a spring contact piece 30a of a battery negative terminal fitting 30'. A switch operating part 80' which is movable in the direction perpendicular to the spring contact piece 91a and has a lever part L, and a battery positive terminal fitting 40' having a springy rising and dropping part 47 on which a conical bent part m to be engaged with a latching part A is located on its end part side are provided. The latching part A has a first recessed part A<SB POS="POST">1</SB>to be latched with the conical bent part m at a right rocking position of the switch operating part 80', a second recessed part A<SB POS="POST">2</SB>to be latched with the conical bent part m at a left rocking position thereof, and a curved projecting part Z located between them. When the conical bent part m is engaged with the second recessed part A<SB POS="POST">2</SB>, the tip part of the lever part L presses the spring contact piece 91a to bring it into contact with the spring contact piece 30a.
