Abstract

The present invention provides a joint spring of high reliability and switch device using the same with a protrusion enabled to be easily formed at the joint spring and with a resistance of a junction part with the protrusion lowered. A The joint spring consists of a spring unit having through hole; a protrusion unit that is inserted and kept in the through hole; a press unit that is formed on the top surface side of the protrusion unit for transferring the external pressure; a connection point unit formed by having another end side of the pressing unit protruded toward a underside of a swollen part of the spring unit. The protrusion unit is held by the through hole not to be pulled off by deforming its outer periphery part so as to pinch it from both a top and bottom faces in a plate thickness direction of the spring unit. A coating material made of a precious metal rich in conductivity is applied onto the top and bottom faces of a periphery edge part of the through hole of the spring unit jointed with the outer periphery part of the protrusion unit.
