THERMALLY-ACTUATED SWITCH

摘要

PROBLEM TO BE SOLVED: To provide a self-holding type thermally-actuated switch having excellent workability and miniaturizable. SOLUTION: This thermally-actuated switch is provided with: first and second fixed terminals 2 and 3 installed on a base 1; a bimetal piece 4 having one end side connected to the first fixed terminal 2 with a moving contact 5 fixed to the other end side; a fixed contact 3 formed on the second fixed terminal 3 and contacting to and separating from the moving contact 5; a positive-characteristic thermistor 9 for keeping reversal of the bimetal piece 4 by being connected to the bimetal piece 4 to generate heat; and a lid body 6 superimposed on the base 1. The thermally-actuated switch is so structured that the positive-characteristic thermistor 9 is mounted on the lid body 6 side; a conductive connection member 7 is installed on the lid body 6; in superimposing the lid body 6 on the base 1, the connection member 7 is connected to the second fixed terminal 3; and the thermistor 9 is connected in parallel between the first and second fixed terminals 2 and 3 through the connection member 7.
