<p>PURPOSE:To improve reliability and reduce cost price while obviating troubles in welding by making a support pin and terminal connected to a drive circuit the same member and connecting a circuit substrate with a Ni wire. CONSTITUTION:A support pin and terminal 6 made of a same member are embedded in a housing 5 to be integrally molded. Then, the support pin and terminal 6 are made of a plate material. A temperature sensitive resistor 7 is welded to an exothermic resistor 8. Also, the support pin and terminal 6 are constructed to project from the housing 5. Then, Ni wire welding pad 3 is soldered to a circuit substrate 2. The support pin and terminal 6 is welded to each other by the Ni wire 4 to electrically interconnect the circuit substrate 2, temperature sensitive resistor 7 and exothermic resistor 8.</p> |
