A multiple circuit switching device with a drain passage comprising:
- a switch body;
- a base plate provided in the switch body;
- a first operating knob provided in the switch body so as to be pushed therein;
- an elastic member arranged on the base plate, the elastic member including an elastically deformable contact holder portion for switching a first switching member in response to a pushing operation of the first operating knob;
- a second operating knob provided near the first operating knob;
- and
- a contact holder for switching a second switching member in response to a switching operation of the second operating knob, the contact holder being slidably arranged on the basis plate,
- wherein the switch body includes at least one water drain aperture opening onto a side wall thereof, said side wall being perpendicular to said base plate.
