THERMALLY-ACTUATED SWITCH

摘要

A thermally-actuated switch (1), comprising a switch body (2) having a metallic pressure-tight sealed container (4) and a contact mechanism installed in the air-tight sealed container (4) and a holder (3) having a base (3A) with an installation surface (3L) for an electric motor (10) to fit the motor to a coil end (11) and a holding part (3B) installed on the surface of the base opposite to the installation surface and holding the switch body (2), wherein the base is formed sufficiently large so that the switch body held on the holding part is not extended from the base, whereby a conductive heat and radiation heat from the coil end can be prevented from directly reaching the switch body when the thermally-actuated switch is fitted to the coil end.
