PROBLEM TO BE SOLVED: To provide a lever combination switch in which reliability is improvable. SOLUTION: A photodiode array 30 is arranged and fixed, and in order that mutually different photodiodes (either one of 31 to 34) receives light guided by a light guide 21, at every position of an operation target of an operated means, an LED 11 and the light guide 21 are integrally slid accompanied with the operation of the operated means. Respective photodiodes 31 to 34 outputs mutually different electric signals to a control circuit 40 when they receive the light guided by the light guide or when they do not. By analyzing the electric signals input by each of the photodiodes 31 to 34, the control circuit 40 specifies the position of the operation target of the operated means based on the difference of the photodiodes (either one of 31 to 34) that received the light emitted from the LED 11.
