Abstract
A lever switch that includes a manipulation lever 5 supported pivotably around a shaft in a case 18, first, second and third movable pieces 17, 25, 26 carrying movable contacts 30, 32, 34 moved by pivoting manipulation of the manipulation lever 5; and a pole plate 27 having a plate surface 27a with fixed contact plates 35a on which the movable pieces 17, 25, 26 are slid. The case 18 includes a partition 18c, and sliding grooves 18a are formed on a lower surface of the partition 18c in a direction in which the second movable piece 25 is moved. Guide arms 25b engaged with the sliding grooves 18a are formed on the second movable piece 25. Instability preventing protrusions 25d, which are in sliding contact with inner walls of each of the sliding grooves 18a, are formed on each of the guide arms 25b. The lever switch thus has movable pieces that have no instability
