Abstract
A pushbutton switch for electronic devices such as watches includes a housing provided with a cavity. A first electrically conducting contact member is mounted within the cavity on an electrically insulating portion of the housing. A diaphragm extends across and seals the cavity. A second resilient electrically conducting contact member is mounted between the first contact member and the diaphragm on an electrically conducting portion of the housing. The first contact member extends through the electrically insulating portion of the housing for forming one terminal of the switch while the electrically conducting portion of the housing forms the other terminal. Depressing the diaphragm deflects the second contact member into contact with the first contact member for electrically connecting the terminals to close the switch.
