There was a problem that warping and twisting occurred in the foil, making it difficult to maintain its full function as a movable contact. [Means for solving the problem] The present invention solves the above problems. A fixed contact element made of synthetic resin and molded with an insert mold, and a gold m71r placed opposite it.
In a switch of the type in which the movable contact of the metal foil contacts and conducts with the fixed contact, the gold II fi
Provide fixing holes in at least two locations around the foil contact, and
The metal foil is press-fitted and fixed to a metal foil fixing plate having a metal foil fixing plate at a position corresponding to the fixing hole, and a ring-shaped metal foil pressing part is further provided in the resin part around the fixed contact. The metal foil is held in place by a ring-shaped metal foil presser and fixed.
次に、その実施例を第１図〜纂３図と共に説明する。 Next, the embodiment will be explained with reference to FIGS. 1 to 3.

On the other hand, the fixed contact element 3 is attached by soldering the external terminal 6 to the printed circuit board 5, as shown in Fig. 3. Referring to , a ring-shaped metal foil holding part 4 is provided on the synthetic resin part of the outer periphery of the fixed contact 7.Therefore, the metal foil fixing plate ik, into which the metal foil 2 has been previously incorporated, is integrated with the fixed contact element 3 from above. As a result, the metal foil fixing plate 1 holds the metal foil 2 in the ring-shaped metal foil holding part 4.
The gold JII foil 2 is fixed so that the fixed contact 7 and the movable contact 8 are kept at 5 it for an appropriate period of time.

しうるという利点がある。As explained above, the present invention press-fits and fixes a metal foil having a movable contact onto a metal foil fixing plate, and then presses the metal foil to a ring molded metal ltI foil holding part around a fixed contact element having a fixed contact. Gold foil! i! Because it is fixed between the foil fixing plate and the ring-shaped metal foil presser, compared to conventional metal foils that are welded together,
This has the advantage that there is no risk of warping or twisting due to the effects of welding heat, the contact gap can be kept constant, and the reliability of the switch can be improved.
