A standard (red) or extended (black) slide actuator gives instant recognition of switch position. Mounting The customer has the choice of straight and angle PCB mounting pins. Contacts Heavy gold plated contacts are available for applications requiring dependable operation under extreme environmental conditions. Soldering and Cleaning Immersion and water jet cleaning is not recommended. Ultrasonic cleaning is forbidden. Manual soldering is required for right angle models and side-by-side mounting.

If manual soldering needs to bedone, the following guidelines have to be adhered to (in accordance to IEC 60068-2-20): Size of tip of soldering iron: 3mm dia. - Type of solder: Sn/Ag/Cu - Soldering temperature: 350°C or 370°C - Soldering time: 5s 1s - In order to avoid overheating, a small break has to be observed between each solder-application - The soldering iron has to be kept clean at all times. - It is mandatory to tin the tip of the soldering iron before the soldering can take place. - When soldering, the tip of the iron has to first pre-heat the "intersection" between pin and circuit, before applying the solder. Electrical characteristics Operating voltage/-current Nominal 12 V, 500 mA Maximum voltage 24 V Minimum voltage 10mV, 1 mA Isolation resistance >10 000 MΩ at 100 VDC Contact resistance
