Switch lock with lighted position indicator

A position indicator for a rotary lock having a barrel with a bezel, the lock being mounted on a plate having a front and a rear and said barrel extending through a hole in the plate and the bezel seated on the front of the plate, comprising:

• first and second lamps in the bezel;
• a rotary switch on the barrel behind the plate and actuated by the rotary lock, the hole in the plate being larger than the lock barrel, said rotary switch having
• a first switch pole controlling load circuits, and
• a second switch pole illuminating one of the lamps when one of the load circuits is closed;
• and
• leads connecting the lamps with the switch and extending outside the barrel through the hole in the plate;
• wherein said first lamp is illuminated when said rotary lock and switch are in a first position, and said second lamp is illuminated when said rotary lock and rotary switch are in a second position.

A lock for switching electric loads, comprising:

• a lock with a rotary member;
• a rotary switch mechanically coupled to the rotary member for rotation therewith, said switch having first and second poles which rotate between first and second positions together with said switch;
• a first contact connected to said first switch pole when the rotary member and switch are in the first position to complete a first load circuit;
• a second contact connected to said first switch pole when the rotary member and switch are in the second position to complete a second load circuit;
• and
• a position indicator having
• first and second indicator lights,
• a third contact connected to the first light, said third contact further being connected to the second switch pole when the rotary member and switch are in the first position to complete a first light circuit, and
• a fourth contact connected to the second light, said fourth contact further being connected to the second switch pole when the rotary member and switch are in the second position to complete a second light circuit.

A switch lock having a position indicator, comprising:

• a switch;
• a rotary member mechanically coupled to the rotary switch for movement therewith;
• a lock barrel within which said rotary member rotates, said barrel having
• a bezel with a front surface and a rear surface with said bezel rear surface having a well therein and being seated against a front portion of a mounting surface, and
• two flat sides on said barrel, wherein said barrel extends through a mounting surface cylindrical opening having one flat side associated with one flat sides of the barrel;
• and
• a position indicator having
• an indicator light secured to the bezel and having leads connected to the rotary switch, said switch being operable to complete a light circuit in one position of the rotary member and switch,
• whereby said light leads extend from the well to the rear of the mounting surface through a space between the barrel other flat side and the opening.

In a switch lock having a forward end and a rearward end and having a lock plug rotatable between three positions with a lock barrel, a key being inserted from the lock forward end, and said lock plug further rotating a switch between three positions to place a first switch pole in a selected one of three positions, a visual switch position indicator, comprising:

• a second switch pole operated with the first switch pole and having three positions;
• a power source connected to the second switch pole;
• and
• first, second, and third lights visible from the lock forward end, each of said lights having one lead connected to ground and a second lead connected to a separate terminal, said second switch pole being selectively connected to one of said terminals responsive to the position of the lock plug.

A position indicator for a rotary lock having a barrel with a bezel, the lock being mounted on a plate having a front and a rear and said barrel extending through a hole in the plate and the bezel seated on the front of the plate, comprising:

• a lamp in the bezel;
• a rotary switch on the barrel behind the plate and actuated by the rotary lock, the hole in the plate being larger than the barrel;
• and
• a wire connecting the lamp with the switch and extending outside the barrel through the hole in the plate, said barrel having a round cross-section with a flat sector and the plate hole being round to accommodate the wire extending along the flat sector on the barrel.

A switch lock, comprising:

• a lock barrel having a bezel, said bezel having a front surface and a rear surface with said bezel rear surface being seated against a mounting surface;
• a lock with a rotary member rotatable in the lock barrel;
• a rotary switch mechanically coupled to the rotary member for rotation therewith, said switch having first and second poles and a contact associated with said first pole for switching loads in accordance with the position of the rotary member;
• and
• a position indicator having
• an indicator light having leads, said light being mounted in a hole in the bezel,
• a well in the bezel rear surface for receiving the leads of said indicator light, and
• a first contact associated with said second switch pole and connected to the light to complete a light circuit in one position of the rotary member and switch.

A switch lock, comprising:

• a lock barrel having a bezel, said bezel having a front surface and a rear surface with said bezel rear surface being seated against a mounting surface;
• a lock with a rotary member rotatable in the lock barrel;
• a rotary switch mechanically coupled to the rotary member for rotation therewith, said switch having first and second poles and a contact associated with said first pole for switching loads in accordance with the position of the rotary member;
• and
• a position indicator having
• an indicator light mounted in a hole in the bezel, said hole having a reduced diameter at the front of the lock ensuring that the light is recessed behind the front surface of the bezel, and
• a first contact associated with said second switch pole and connected to the light to complete a light circuit in one position of the rotary member and switch.
