Abstract:
1. A thermoprotector having: an insulation housing; stationary electrodes which are opposed to each other in said insulation housing; an elastic movable conductor which is placed between said stationary electrodes, one end of said elastic movable conductor being fixed to one of said stationary electrodes, said elastic movable conductor being compressed in a longitudinal direction and elastically curved to cause a middle of said elastic movable conductor to be contacted with another one of said stationary electrodes, another end portion of said elastic movable conductor being face joined by a fusible material to said one stationary electrode against a reaction force of the longitudinal direction compression; and an insulation spacer which is disposed in said insulation housing, said insulation spacer forming a space for housing said other end portion of said elastic movable conductor when said elastic movable conductor is elastically released by melting of said fusible material.
