Slide switch

摘要

A slide switch has a first small-current fixed contact, a second small-current fixed contact, a first large-current fixed contact and a second large-current fixed contact all disposed on a board. A movable contact member is movable along the board and includes a first small-current movable contact, a second small-current movable contact, a first large-current movable contact and a second large-current movable contact, all of which are integrally formed together. The first small-current movable contact is adapted, according to the movement of the movable contact member, to be brought into contact with the first small-current fixed contact. The first large-current movable contact is adapted, according to the movement of the movable contact member, to contact the first large-current fixed contact. The second small-current movable contact is continually in contact with the second small-current fixed contact. The second large-current movable contact is continually in contact with the second large-current fixed contact.
