Abstract A switching apparatus is provided for a vehicle locking device which is easy to assemble, provides accurate operation, and uses a return spring separated from the switch contacts. A recess portion for receiving a latch and a ratchet for preventing the reversing of the latch is formed in a base plate made of a synthetic resin so that the latch and the ratchet are mounted in the recess portion. A further recess portion is provided for receiving a cartridge at the back of the first recess portion, the cartridge being provided with a half-latching fixed contact, a fully-latching fixed contact and an open-state fixed contact which each have the form of a circular arc with a latch shaft at the center of the arc. A return spring for reversing the latch is received in an arc-shaped inner groove, and a movable contact which is brought into con-tact with each of said fixed contacts has a boss adapted to engage with one end of the return spring in the arc-shaped inner groove. The latch is received in the first recess portion after the cartridge has been received in the second recess portion so that a projection from the latch is engaged with the boss of the cartridge.
