Abstract
A camera is usable to observe a switched position of a switch contact of a switchgear apparatus. In an embodiment, the camera includes a light source to illuminate the switch contact, an image sensor, and a lens to focus light beams emanating from the switch contact onto the image sensor. In an embodiment, the camera additionally includes an elastic light protection cap to seal off a beam path, from the lens to the image sensor, from the light source in a lightproof manner.

A camera to observe a switched position of a switch contact of a switchgear apparatus, the camera comprising:
- a light source to illuminate the switch contact;
- an image sensor;
- a lens to focus light beams emanating from the switch contact onto the image sensor;
- an elastic light protection cap, to seal off a beam path, from the lens to the image sensor, from the light source in a lightproof manner;
- and
- a camera housing, enclosing the light source and the image sensor, wherein the lens is received in a through opening of the camera housing, wherein the light protection cap is embodied in a tubular fashion and bears by a first end of the light protection cap against an inner wall of the camera housing and by a second end of the light protection cap against a surface of a printed circuit board (PCB), the light source and the image sensor being arranged on the PCB, wherein the light protection cap is embodied in a form of a tube having a double-C shape in section along a longitudinal axis of the tube.
