ABSTRACT:
A battery switch plate is disclosed having a U-shaped frame that receives and supports a timepiece battery and that also provides electrical contact between the positive battery terminal and the timepiece integrated circuit via a lead frame. The switch plate, which is received by an aperture in the rear pod of the timepiece module, holds the battery in position and permits the negative battery terminal to come into contact with another lead frame conducting member. Switching occurs to correct and change timekeeping function of the timepiece when switch contacts are independently forced into electrical contact with underlying leaf spring members that are attached to and extend oppositely outward from the ends of the U-shaped frame or when the leaf spring members are independently forced into electrical contact with underlying switch contacts.
