Patent number: 9514906Abstract: A temperature switch performs switching according to temperature of a heater. The temperature switch includes a bimetal that is deformed when the temperature of the heater reaches set temperature, a switch mechanism that is opened and closed by deformation of the bimetal, and a housing member that houses the bimetal and the switch mechanism, and that is able to conduct heat to the bimetal. The heater includes a pair of heat generation units that is adjacent to each other. The housing member includes a contact portion that is formed to project and that is inserted between the pair of heat generation units.Type: GrantFiled: July 24, 2013Date of Patent: December 6, 2016Assignee: CALSONIC KANSEI CORPORATIONInventors: Daiju Suzuki, Naohisa Kamiyama, Hiroki Yoshioka, Atsushi Kawashima, Takeshi Satoh, Takeshi Ogasawara
