点６は固定接点１４と接触する。Note that when fixing the bimetal element 1 within the frame,
As shown in FIG. 3A, a compressive force Px is applied to the end of the center member (horizontal member), the ends of the side members 3 and 4 are fixed, and the center member 2 is displaced by Δt and fixed, When the movable contact 6 is lifted upward and brought into contact with the lower fixed contact 14', the movable contact 6 comes into contact with the fixed contact 14 with a contact pressure Po.
この状態でバイメタル素子１が加熱されると、バイメタ
ル素子１は反転して可動接点ｉは上方の固定接点１４′
と接触する。When the bimetal element 1 is heated in this state, the bimetal element 1 is reversed and the movable contact i is connected to the upper fixed contact 14'.
come into contact with.
さらにバイメタル素子の温度が低下すれば、再び可動接
点６は下方の固定接点に接触するに至る。When the temperature of the bimetal element further decreases, the movable contact 6 comes into contact with the fixed contact below again.
第３図口、ハに示すように可動接点の接点圧をＰ、サイ
ドメンバーの端子が摺動するストロークをＷｚとすると
、バイメタル素子の上昇温度θとの関係は第４図に示す
ようなヒステリシスを有する運動を行う。If the contact pressure of the movable contact is P and the sliding stroke of the terminal of the side member is Wz, as shown in Figure 3, the relationship with the temperature rise θ of the bimetal element is hysteresis as shown in Figure 4. Do an exercise that has.
図において実線は温度θとストロークＷｚとの関係を、
一点鎖線は接点圧ＰとストロークＷｚとの関係を示す。In the figure, the solid line represents the relationship between temperature θ and stroke Wz,
A dashed-dotted line indicates the relationship between contact pressure P and stroke Wz.
図においてθとＷｚとの関係をみると、ある温度におい
てＷｚは水平方向に跳躍しているため、可動接点の移動

チは速断的に作動することが認められる。Looking at the relationship between θ and Wz in the figure, since Wz jumps in the horizontal direction at a certain temperature, the movement of the movable contact is also instantaneous, and as a result, the thermoswitch of the present invention operates rapidly. It is recognized that
第５図はバイメタル素子の他の実施例を示すもので、図
