PROBLEM TO BE SOLVED: To provide a lever combination switch capable of improving reliability. SOLUTION: The magnetic sensor 30 has sensor elements (any one of 31-38) which are arranged fixedly and are mutually different for each position of operation object of the operating means and in which a magnet 10 and a magnetic body 20 are integrally displaced accompanying operation of the operating means so that it may receive magnetic field guided by the magnetic body 20 in a manner the magnetic flux density becoming higher than the other sensor element. Each of the sensor elements 31-38 is a magnetic resistance element in which its electric resistance value becomes smaller, the higher is the magnetic flux density of the magnetic field it has received, and its both end voltage is monitored by a control circuit. The control circuit monitors the both end voltage of each of the sensor elements 31-38, and thereby, identifies the position of the operation object of the operating means based on the difference of the sensor elements in which the magnetic field guided by the magnetic body 20 is received in a manner the magnetic flux density becoming higher than the other sensor element.
