Ceramic trimmer capacitor

A disc trimmer capacitor comprising,

• a rotor having one face flat,
• a first bore normal to said flat face, an electrode spaced from said flat face and having an extension to said first bore, a shaft fixed in said first bore and electrically connected to said extension,
• a stator having one face flat and presented to the flat face of the rotor, a second bore normal to its flat face and of greater diameter than and concentric with the first bore, the opposite face of the stator being recessed to provide a socket with a shoulder surrounding and spaced radially outward of the second bore, a stator electrode on its flat face having an extension to the second bore and to said shoulder, said stator electrode engaging the flat face of the rotor,
• a stator lead having a flat head received in said socket and engaging the stator electrode extension on said shoulder and having a clearance opening surrounding and spaced radially outward from said shaft,
• a rotor lead having a flat head received in said socket and an opening centered on said shaft and of smaller diameter than the opening in the head of the stator lead, and
• a washer of insulating material on the head of said rotor terminal engaging the head of the stator lead and spacing the rotor lead from the stator lead.
