Abstract:
A switch, which has a concave-shaped housing with one side opened, a cover to seal the opened face and a fixed conductive contact member and a movable contact member placed face to face with each other in the housing such that an operative force of operation members that are held in the housing and operated is transmitted to the movable contact member so that the movable contact member is moved and shifted to connect and separate the contacts to perform a switching operation, comprising:a common fixed contact member and a fixed contact member, different from the common fixed contact member, placed in parallel with each other in the housing, and said movable contact member having a tilt-movement fulcrum portion placed orthogonal to the parallel arranging direction of respective fixed contact members, freely tiltable in the orthogonal direction, while being pressed toward a common fixed contact member side, at an intermediate position on one side member of a conductive plate spring member formed into a U shape, and a contact portion formed at one end of the one side member in a length direction with the tilt-movement fulcrum portion in a movable shifting direction of the one side member serving as a base point, wherein a contact switching mechanism, which performs a switching operation by reversing the movable contact member in a seesaw manner, based upon the operative force of the operation members that are in contact with the movable contact member along an outer face length direction on the other side member thereof, with respect to contacting and separating processes between the contact portion of the fixed contact member and the contact portion of the movable contact member that are placed face to face with each other, with the tilt-movement fulcrum portion of the movable contact member being in contact with the contact portion of the common fixed contact member, is installed.
