Abstract:
A tact switch comprising:an insulative base having separated contacts each of which has an exposed portion exposed to exterior, wherein the exposed portions of the separated contacts face upward;two separated steps formed in the insulative base and located beyond the exposed portions of the contacts;a conductor plate having a frame positioned on the separated steps, an integral contacting portion surrounded by the frame and connected to the frame via two spring arms, normally the integral contacting portion registering with and spaced away from the exposed portion of the contacts; andan elastic means positioned on the conductor plate;wherein the elastic means is deformable by depression thereon to thus deform the spring arms of the conductor plate and move the integral contacting portion of the conductor plate downward to electrically connect the exposed portions of the separated contacts simultaneously, and when the depression on the elastic means is released, both the elastic means and the spring arms of the conductor plate will recover from deformation and the integral contacting portion of the conductor plate separates from the exposed portions of the separated contacts; andwherein the elastic means is a metal dome.
