<p>PURPOSE: To perform sure reverse switching for each operation of a key slider by causing a control cam to displace a release lever in the specified rotational direction of a switch vehicle and a cooperative action between the release lever and the key slider is lost during switching. CONSTITUTION: When a key slider 14 is pushed in, the key slider 14 moves a release lever 13 in a longitudinal direction via a switching projection 15 and a contact surface 16 and displaces a lock lever 11 operated cooperatively with this release lever 13 in the following manner. That is, the lock lever 11 releases a stopper surface 10 and the locking of a switch vehicle 2, then the pre-loaded switch vehicle 2 connected to a switch slider 1 via a first spring 9 is engaged with the teeth of a driving gear 3 by a rim with teeth 4 and the switch vehicle is driven. Then, by a second spring 17, the release lever 13 is returned again to the starting position of a longitudinal direction movement.</p> |
