A lighting apparatus for a vacuum apparatus that allows light to enter the inside of the vacuum apparatus through an observation window and makes it possible to see the inside of the vacuum apparatus through the observation window by illuminating the inside of the vacuum apparatus includes a coupling adapter that is removably coupled to the observation window via a coupling unit, an opening that is formed in a central part of the coupling adapter and allows the inside of the vacuum apparatus to be seen through the observation window, and a plurality of LEDs (light-emitting diodes) that are placed in the coupling adapter and face the observation window. The lighting apparatus is attached to the observation window for seeing the inside of the vacuum apparatus and illuminates the inside of the vacuum apparatus.

In a monitoring and control device for use in a remote monitoring and control system, a device housing has a socket located behind a display panel and an external storage medium including a rewritable memory is removably mounted in the socket. The device housing is attached in an attachment hole formed in a wall in a state that the external storage medium is mounted in the socket. A control unit performs a setting operation for a graphic image displayed on the display panel and for the load control in accordance with setting information stored in the external storage medium. The external storage medium is inserted in the socket through an insertion slot formed in a side portion of the device housing, at least a portion of the insertion slot being received in the attachment hole in a state that the device housing is attached to the wall.

Provided is an electromagnetic relay which does not require a braided wire for securing a current capacity of a main contact unit. The electromagnetic relay includes a main contact unit 2 A inserted into a power supply path to a load and an arc contact unit 3 A connected in parallel to the main contact unit 2A. An auxiliary contact unit 4 is electrically independent of the main contact unit 2 A and the arc contact unit 3A. The main contact unit 2 A includes a main fixed contact 27 fixed to a frame body 1 and a main contact spring 23 made of a leaf spring and fitted with a main mobile contact 25 which is attached to and detached from the main fixed contact 27. The arc contact unit 3 A and the auxiliary contact unit 4 are arranged adjacent to each other. The main contact spring 23 extends in a direction in which the arc contact unit 3 A and the auxiliary contact unit 4 are arranged. Therefore, the main contact spring 23 can be formed with a large length in the frame body 1 and the sectional area can be enhanced without increasing a spring constant, thereby not requiring a braided wire.

There is provided a monitor and control apparatus capable of enlarging a volume of a body, while ensuring a space for routing signal lines between a rear face of the body and a bottom surface of a mounting hole. The body 5 has a rear face including: a first face having terminal sections protruded; and a second face protruded backwardly relative to the first face by a stepped portion. An internal space of the body on the second face side is enlarged backwardly more than that on the first face side. The stepped portion is formed in the middle of the rear face of the body in the horizontal direction, which defines a right-half portion as the first face, and a left-half portion as the second face.

The device control system includes: a device controller connected to a load device via a signal line; a wireless master connected to the signal line; and a wireless slave. The device controller outputs a first control signal indicative of an intended state of the load device when receiving a second control signal from the wireless slave via the wireless master or receiving via the signal line a third control signal sent in response to a state check signal. When receiving a state change notice sent in response to the first control signal, the device controller sends the state change notice to the wireless master. When receiving the state change notice, the wireless master sends the received state change notice to the wireless slave.

An illuminance sensor setting device includes: an illuminance sensor that outputs a signal for switching a lighting apparatus, and a setting unit that performs setting of the illuminance sensor. The illuminance sensor and the setting unit are provided separately from each other, and are connected to signal lines. The setting unit has a configuration to set a sensor address of the sensor, a control address of the lighting apparatus, and an illuminance reference for switching the lighting apparatus. The setting unit transmits to the signal line the setting signal and the sensor address. Thus, even if the illuminance sensor is provided on, for example, the ceiling in the vicinity of the lighting apparatus, the setting unit can be provided at any place, such as a wall, where the setting unit can be easily operated, and work for settings is facilitated.
