Switch device

Abstract

Disclosed is a switch device that includes or is formed by a switchgear. Two sensors of the switchgear monitor two measured values and a switch of the switchgear is switched depending on these measured values. The adjustable thresholds for the measured values are displayed on a digital display integrated in the switchgear or arranged on an external input device. Both thresholds are adjusted digitally via the input device. The input device can be a commercially available smartphone with an app or a laptop.

Description

(1) An embodiment of the switch device according to the disclosure is shown in the Figures.

(2) FIG. 1 shows the embodiment of the switch device according to the disclosure in one view,

(3) FIG. 2 shows a view of the upper end face of the switchgear of the switch device of FIG. 1,

(4) FIG. 3 shows a view of the lower end face of the switchgear of the switch device of FIG. 1 and

(5) FIG. 4 shows a schematic of the switchgear of the previous Figures.

(6) FIG. 1 shows the embodiment of the switch device according to the disclosure. It has a switchgear 1 and a commercially available laptop 2, which are connected via a USB cable 4. The switchgear 1 has an essentially cuboid housing 6, with a mini USB connector 10 (not shown in more detail in FIG. 1) provided at its upper end face 8.

(7) The switchgear 1 has five numbered electrical connections 16 at its lower end face 14. The electrical connections 16 are provided as entries for cables or litz wires. They are screw-fastened by means of so-called paternoster clamps, whereby they are screwed through access openings 17 without removing a cover.

(8) FIG. 4 shows a schematic of switchgear 1. A combination of a thermostat 18 and a hygrostat 20 is provided inside of it, wherein the switchgear is also called hygrotherm. The two electrical connections 16 with the numbers 1 and 2 are used to supply the thermostat 18 and the hygrostat 20. An adjustable threshold is stored in the thermostat 18 and the hygrostat 20, respectively. Via a temperature sensor and a sensor for relative humidity, a respective currently measured value , is regularly determined. As soon as one of the two currently measured values , reaches the assigned threshold, a switch 22 is switched, whereby the two electrical connections 16 with numbers 3 and 5 are connected to each other. This supplies power to an electric heater 24 and heats the ambient air of switchgear 1, thus reducing the relative humidity. As soon as the concerned measured value , falls below the adjusted threshold again, the switch 22 is switched back to the position shown in FIG. 4, whereby the heater 24 is switched off. Instead of the heater shown in FIG. 4, one or more other electrical loads, for example fans, can also be switched.

(9) FIG. 1 shows respective ventilation slots 26 at the upper end face 8 and at the lower end face 14 of the housing 6. Moreover, through recesses 30 are also provided at a front side 28 of the housing 6 so that the thermostat 18 and the hygrostat 20 or respectively the switchgear 1 can react to changes in the ambient air as quickly as possible.

(10) The adjustment of the thresholds for temperature and relative humidity are input via a keyboard 32 of the laptop 2 and shown on a display 34 of the laptop as well as on a display 35 of switchgear 1. Furthermore, the currently measured value of the temperature and the currently measured value of the relative humidity are also displayed on both displays 34, 35. Finally, the state of the switch 22 (cf. FIG. 4) is shown on both displays 34, 35.

(11) Data is exchanged bidirectionally between the laptop 2 and the switchgear 1 via a USB interface of which only the USB cable 4 is shown in FIG. 1.

(12) FIG. 2 shows the upper end face 8 of the housing 6 of the switchgear 1. The large number of ventilation slots 26 and the mini USB connector 10 is shown into which a plug of the USB cable 4 (cf. FIG. 1) can be inserted.

(13) Furthermore, FIG. 2 shows two clip elements 36 formed in one piece with the housing 6, both of which can encompass a common side of a DIN-standard top-hat rail (not shown), with which the housing 6 of the switchgear can be fastened in a switchboard equipped with the corresponding rail.

(14) FIG. 3 shows with a view to the lower end face 14 of the housing 6, two further clip elements 38 formed in one piece with the housing 6, which are opposite to those of FIG. 2 and can thus encompass the top-hat rail (not shown) on their opposite side.

(15) In a preferred case of application, the switchboard contains a programmable logic controller (PLC) whose electronic and electric elements are protected from the formation of condensate from the ambient air by the switch device according to the disclosure.

(16) As was already explained in the introduction of the description, as an alternative to the embodiment shown, a smartphone can be provided as input unit instead of the laptop 2, and/or a wireless data transfer via Bluetooth instead of USB cable 4. A corresponding app is then installed on the smartphone.

(17) Disclosed is a switch device that includes or is formed by a switchgear. Two sensors of the switchgear monitor two measured values, and a switch of the switchgear is switched depending on these measured values. The adjustable thresholds for the measured values are displayed on a digital display integrated in the switchgear or arranged on an external input device. Both thresholds are adjusted digitally via the input device. The input device can be a commercially available smartphone with an app or a laptop.
