Title: Thermosensitive switch
Inventor: SATO SHIGEMI
IPC: H01H37/54
Filed: 2001-08-21
Abstract: PROBLEM TO BE SOLVED: To obtain a thermosensitive switch capable of preventing another spark between the contacts by absorbing the impact of the reversion of a thermally-actuated plate when the contact is opened. SOLUTION: A buffer plate 16 composed of a metallic plate having elasticity is fixed to a thermally-actuated plate support 10. The back side of the thermally-actuated plate is brought into contact with a contacting part 16A arranged on the tip of the free end part of the buffer plate 16 when the thermally-actuated plate 12 is reversed. The buffer plate 16 restricts the moving distance of a movable contact 14 by supporting the thermally-actuated plate 12 from the back when the thermally-actuated plate 12 is reversed, absorbs collision energy when it is reversed and suppresses a rebound of the movable contact. Accordingly the consumption of the contacts can be suppressed by restricting the distance between the contacts, suppressing arc energy and preventing another spark, therefore, the life of the switch 1 can be extended.
