Abstract
A normally closed electrical switch includes a first circuit board having a first switch contact thereon and an aperture therethrough near the first switch contact. A second, flexible circuit board has a second switch contact aligned with the first switch contact of the first circuit board. A spacer sheet separates the first and second circuit boards and has an aperture in registry with the aperture in the first circuit board. The switch contacts extend toward each other through the aperture in the spacer sheet such that they are in normally closed condition. A movable cover is provided on the first circuit board at least over the aperture therein. An actuator is operatively associated with the cover and extends through the aperture in the first circuit board, through the aperture in the spacer sheet and engageable with the second, flexible circuit board for flexing the second circuit board and opening the switch contacts in response to movement of the cover. At least one of the circuit boards may be embossed in the area of its respective switch contact so that the contact projects through the aperture in the spacer sheet.
