In summary, the advantages of key switches are as follows: Security through key-lock mechanism, additional security through long-term available key forms and spare keys, multitude of individually determinable functions, authorizations tailored to users, surface or flush mounting options, simple integration into complex operating systems and the matching appearance to further command and signaling devices.

Of course, the easiest way to achieve this is to find a partner who accompanies you throughout the entire process and also has all the technologies in its portfolio: Touchscreens, housings, software, computers, joysticks, electromechanical systems, pushbuttons, illuminated pushbuttons, key switches and signal lights. This is particularly important if the Human Machine Interface is not only to function perfectly and safely, but also to convey a uniform brand message. Key-operated switches that you purchase from a manufacturer that carries other control and signaling devices such as pushbuttons, switches or signal lamps ensure a harmonious appearance in combination with the other articles in the series. Added to this is the increasingly important design aspect. Thanks to its practical dimensions, the product can be easily placed behind the front panel or flush-mounted. These exemplary possibilities show well how variable the switches can be used in everyday work.Īnother advantage of the key switch is its simple integration into HMI systems such as plant control systems, elevator control panels or alarm systems. A possible level 4 here could be a master key that resets the entire plant and its controls to default settings if it is to be disposed of or rebuilt. Once the part is then removed, work can continue for the plant operator. To remove the part, the shift supervisor must put the plant into maintenance mode with authorization key level 3. There, he recognizes from the information displayed that a part is jammed. He uses his key of the next higher authorization level to call up a specific program within the plant control system in which he can diagnose the fault. The plant operator calls the foreman for help. In the course of the shift, an unforeseen malfunction occurs. Selectable LED colours (turns from red to green or green to red) when activated, selectable by a simple PCB jumper.In a fictitious production plant, this could look as follows: The plant operator starts the plant at the beginning of his shift by turning his authorization key to the maximum possible position 1.Simple screwless wire terminal connectors.Built-in 3A SPDT relay with Common, Normally Closed and Normally Open connections.Fixed detection range typically 4" Inches (10cm) or less from the sensor.Passing your hand across the sensor briefly will activate the relay for 0.5 seconds, holding a hand in front of the sensor will keep the relay activated constantly until the hand is removed. Upon hand detection the built-in 3A SPDT (Single Pole, Double Throw) relay will activate for a minimum period of 0.5 seconds, or remain on for the duration that the hand is in front of the sensor. The sensor is mounted on a stainless steel single gang plate, a hand passing within 4" Inches (10cm) from the plate sensor will activate the internal relay and change the LED colour. Since it is No-Touch it is ideal for offices, schools, clinics, labs, village halls, factories and washrooms to reduce the risk of bacterial contamination from hand to hand and useful in the prevention of coronavirus. The features of the key lock switch in 32A include: Impact and Chemical Resistant Raised ON/OFF Lettering 8mm Lockable Handle Key Lockable in ON and OFF. Indoor No-Touch request to exit sensor uses infrared technology to request exit from a protected area, or device, with a simple wave of a hand.
