Preferably, there is tongue and groove edge above its insulation shell, and its heating board edge has and had and its tongue and groove position one
The buckle of cause, over hot melting caused by avoiding the use institute of traditional sealing possible evaporate, and influencing contactor conducting, heating board play are wrong
The failure of position occurs.
Preferably, its fixed touching plate for can not movable contact spring, be disposed with spring chuck on its fixed touching plate, its movable contact spring is reciprocal curved
Shape metal clips is rolled over, contact and spring chuck is distributed with its metal clips, its electrode a and electrode b by fixed touching plate and are moved tactile
Piece is connected conducting with the first power spring and the second power spring respectively.
Preferably, its electric resistance alloy is nickel-base resistance alloy.
Beneficial effect：The utility model jumps disconnected mode using bimetal leaf temperature-sensitive and the break-make of heater circuit is controlled,
It is automatic jump it is disconnected, it is unattended cut off the electricity supply in the case of will not multiple connection be logical heats again so that more pacified with the electrical equipment of this controller
Entirely；When being sent a telegram here again after accident power-off in addition will not continuous heating, the overall safety of electrical equipment, the long-time of original paper can be ensured
Use, and user is first pulled out plug deenergization somewhat cooling controller when reusing just using the design
It can reuse, the good habit that user can be helped to be powered off after forming use, so as to thoroughly break off the hair of unexpected danger
Raw, new material, the heating board of structure better ensure that the realization of design performance in addition.
