ABSTRACT:
The circuit element contains inside a cup-shaped plastic housing (3) a gas-tight primary battery (B) and a wiring arrangement which is arranged next to the battery (B) in the hollow space (3') of the housing and which comprises semiconductor switching elements (D.sub.1, Tr) and conductor connections (8, 13/13', 15, 16). The battery (B) and wiring arrangement are hermetically disposed in the housing (3) as a result of a casting compound (19).
The switching element is provided with plug-in pins (13/13', 16) which are brought out to its surface and which can be directly soldered into a circuit board. Switching elements of this type can be used especially as backup voltage source for memory systems of the non-self-holding type.
