Claims

[Scope of utility model registration request]

An actuating body is installed in a cylindrical case with one side open, and the actuating body is moved from a first position where there is no pushing operation to a second position in the axial direction of the case by a pushing operation from outside the case. An insulating substrate is fixed to the cylindrical case so as to cover the open surface, and a first insulating substrate is fixed to the cylindrical case so as to cover the open surface. A second fixed contact is formed on the plate surface so as to surround the first fixed contact, and a second fixed contact is formed in the cylindrical case between the insulating substrate side end of the actuating body and the insulating substrate. A substantially plate-shaped reversing contact having a spherical pressure contact portion is attached with the spherical pressure contact portion facing the insulating substrate side end of the actuating body, and these reversing contacts are in contact with the second fixed contact. An engaging leg piece extending toward the insulating substrate side is integrally formed from the peripheral contact leg part, and this engaging leg piece is engaged with an engaging part formed on the second fixed contact, and the engaging leg piece is engaged with an engaging part formed on the second fixed contact, and In the position, the spherical pressure contact portion is concave with respect to the first fixed contact and is in a non-contact state with the first fixed contact, and in the second position, the spherical pressure contact portion is in contact with the first fixed contact. A tact switch characterized in that it is configured to be inverted in a convex manner with respect to the contact and come into contact with the first fixed contact.
