General description

The Series 09 Universal Switch family has been developed for E1 applications, includes an integrated connector recess and is ideally suited for use in vehicle interiors – in particular for various switching controls in passenger cars, electric vehicles, trucks, buses and special vehicles. The S09 Universal Switch is available in different configurations and combinations for a large range of applications. Thanks to the diagnostic capability through resistance coding (Namur), for example cable breaks and switching states can be detected. There is also the option of two redundant switching signals.

• White symbol illumination with three, one or without red LED status indicator
• Red Symbol Illumination e.g. for use as a hazard warning light
• Indicator version without mechanical function with and without illumination
• Two different haptic variants (firm or soft haptic)
• Two different connector coding’s
• ISO 7000 or customized symbols
• Standard Single Contact or Dual Contact (Two redundant switching signals)
• Optional diagnostic feature through resistance coding (Namur)

Typical applications
Wide range of typical vehicle applications due to multi-status indication – in particular: Climate Control, Menu navigation, central locking, Seat Heating and many others. The universal switch can be also used for safety-relevant applications, for example Hazard Warning Switch, Chassis- and Transmission Control or Parking Brake. Thanks to the diagnostic capability through resistance coding (Namur), cable breaks and switching states can be detected. The redundancy of the switching contacts of the dual-contact versions speaks for itself.

The customer must ensure the functional and product safety conformity of the integration of the switch. Therefore, the customer must perform all security activities at the integration level of the switch and confirm that all relevant functions are implemented to ensure that the application handles critical issues in a secure manner.

The installation space of the switch must provide a drain for liquids on the plug contact side in order to protect the switch from being flooded.

Attention
The protection degree of up to IP5K4 to be achieved, depends on the front panel and type of mounting used, and must be ensured by the customer.

• Flooding might cause Risk of injury
• Damage to the pushbutton/indicator, connector

Scope of delivery

Note
The Symbols (ISO 7000 or customised) must be defined separately within the configuration of the switch.

Storage

Note
Avoid abrupt changes in the storage temperature of the Pushbutton or indicator as well as condensing environment.

• Damage to the pushbutton or indicator

Do not expose the open contacts of the unprotected connector to condensing air humidity.

• Damage to the pushbutton or indicator
• Corrosion of electrical contacts

Check the delivery immediately after unpacking regarding completeness and transport damages. If any damage or incompleteness is found, please contact the supplier immediately.

Mechanical installation/ mounting

Installation in a panel by means of retaining clamps.
See drawing “1901940001 product information”

The switches are designed for one-time assembly. During disassembly, there is a risk of abrasion or breakage of the mounting clips. This can lead to a reduction in the holding force. We therefore recommend replacing the Universal Switch after it has been mounted/ dismounted and damages to the mounting clips are detectable to not endanger safe and tight fit. The Switch/Indicator must be pressed evenly into the panel of the customer application, avoiding tilting. Do not overload the actuating surface of the cap, otherwise the mechanics and electronics inside the button/indicator may be damaged. While assembling take care of ESD protected environment and tools.

Note

• Damage to the buttons
• Damage to the tight fixation

The plug-in connection must be established with a suitable connector. The plug-in connection can alternatively be established before or after mounting the Universal Switch into the panel.

Use outside closed vehicles
The S09 Universal Switch is designed for vehicle interiors, protected from environmental influences. The product is validated in accordance with ISO16750 and designed for this application scenario. Any other use is at the user´s own risk and out of warranty of EAO.

Electrical installation and pinning

Electrical installation shall only be done when the system is under no power.

Connection of the Pushbuttons is realized with the following components of Tyco Electronics:

• Tyco-Art.-No. for housing: 1745000-3, 1745000-4
• Tyco-Art.-No. for cage: 965601-2
• Tyco-Art.-No. for contacts: 5-963715-1 (0.5 – 0.75 mm²), 5-928999-1 (0.25 – 0.35 mm²)

Please refer to “1901940001 product information”. Following Picture 1 shows the internal electrical circuit of the Pushbutton. To reduce power dissipation and to prevent overheating of the Pushbutton, variants for 12 V (supply voltage range: 8 V – 16 V) are available. The pinning of the connector of these voltage variants are identically.

The symbol and functional illumination of a button uses the same ground on pin 7 of TE 1745000-x. Each functional illumination can be switched on by connecting pin 2, 4, 8 of connector with positive power supply. The symbol illumination can be switched on by connecting pin 3 of the connector to positive power supply.

Internal resistor values
The values of the resistors for the buttons are:

Without Namur Circuit

• Rp = not placed
• Rs = 0 Ω

With Namur Circuit

• Rp = 1 kΩ
• Rs = 120 Ω

Furthermore, it is necessary to debounce the switches. This can be done via software or hardware in the control unit connected to the keypad and is in customers responsibility. The debounce time should be greater than 10ms.

Cleaning

Cleaning the Pushbutton cap with water and commercially available soft cloths is possible. Do not use aggressive solvents or hose cleaning.

Attention
Avoid contact with liquids on the plug contacts Avoid excessive use of liquids like splash

• Damage to the buttons
• Corrosion to electrical contacts

Liability for quality defects

The general function of the pushbutton/indicator has been tested at the factory before delivery. However, if errors occur despite the careful quality control, they must be reported immediately to EAO or the dealer.

The liability for quality defects is 12 months for the delivered products. Within this period, faulty parts, except wear parts, the pushbutton/indicator has to be returned to EAO. Damages caused by improper use, handling or the use of force are excluded from the liability for quality defects. Damages caused by repairs or modifications to the Pushbutton are also excluded. EAO is exclusively responsible for repairs to the pushbutton/indicator. Further claims cannot be asserted. Claims arising from the purchase contract remain unaffected. EAO is not liable for consequential damages. The right to design changes, in the sense of product improvement, is reserved by EAO.

Emergency Situations
No special measures are required in an emergency from the point of view of the Pushbutton. Required measures are to be evaluated by the customer on the customer application side and implemented to the application, if necessary.

Service, repair

In case of a defective Pushbutton or indicator, please contact your dealer. In case of malfunctions, the cause of which you cannot clearly identify, please send the defective device to the following address:
EAO Automotive GmbH & Co. KG Service Richard-Wagner-Strasse 3 08209 Auerbach/ Vogtl. Tel: +49 (0)3744/ 8264-0 Email: service.esa@eao.com www.eao.com.

Market surveilance
The Pushbutton switch is intended for use in various customer applications and is used for a wide variety of functions in the applications. The manufacturer of these customer applications is therefore not EAO as the manufacturer of the switches or pushbutton products. The responsibility for market surveillance within the meaning of REGULATION (EU) 2019/1020 OF THE EUROPEAN PARLIAMENT AND THE COUNCIL of June 20, 2019 on market surveillance and product conformity and amending Directive 2004/42/EC and Regulations (EC) No. 765/2008 and (EU) No. 305/2011 is therefore the responsibility of the manufacturer of the customer application.

Decommissioning, disposal
Disconnect the system from the power supply before the disconnection. Do not pull at the cable when removing the connector. Dispose of the device, components and accessories, packaging materials and documentation in accordance with the country-specific waste treatment and disposal regulations in the area of use.
