General Information
best results with Switches Usage Guidelines
These guidelines offered users switches ensure successful reliable switch operation. Temperature Both UNIMEC MULTIMEC switches produced standard high temperature materials. Please technical specifications details operating storage temperatures soldering guidelines make sure select switch best suited your application. When flow soldering, strongly recommend that temperature profile analysed compared with temperature rating switch. case doubt always select high temperature version 3XXH9. accessories both UNIMEC MULTIMEC switches made from plastic with maximum operating temperature 65°C. Care must taken overheat accessories during soldering process. soldering processes exposing switch high temperatures strongly recommended that accessories mounted after soldering. LED's have their temperature specifications. When fitted high temperature switch will determine max. operating temperature, i.e. 3FTH922 upper temperature limit 85°C 160°C! When infrared reflow soldering used, very important monitor surface temperature switch during pre-heat stage prevent excessive heat buildup overheating during soldering. Mounting switches mounted rows critical that recommendations regarding spacing followed. board thickness should 1.6mm terminal hole diameters should 0.9mm. UNIMEC MULTIMEC caps bezels easily snapped onto switch modules changed later time with exception UNIMEC 16.700 cap. Once this installed designed removed. cause damage switch board done with extreme care. 16.300 16.700 must removed from alternate action switch, make sure that switch actuator released, upper position before attempting remove cap. This will prevent possible damage internal latching pin. Care must taken when inserting switch assembly into board. press direct LED. This will force down into actuator cause switch contacts remain closed position. correct fault, must raised slightly centered actuator assure unrestricted movement actuator. Soldering Cleaning UNIMEC Most assembly field problems experienced users unsealed switches caused contamination contacts during soldering cleaning. Contact contamination recognized increase contact resistance possible intermittent operation switch, especially power applications. Care must taken submerge switch solder bath spray switch during cleaning. switch must protected times prevent contamination flux cleaning fluids. Soldering Cleaning MULTIMEC MULTIMEC switches fully sealed IP-67M specifications prevent solder flux aqueous solvent cleaning solutions from entering switch contaminating contacts. switches placed board with other components wave soldered. special handling MULTIMEC switches required, notice guidelines mentioned under "temperature".
Soldering Multimec
Through hole versions Hand soldering: 350°C max. this applies both temperature high temp. versions. Wave soldering: Heat built switch during pre-heating soldering must exceed maximum operating temperature switch. some reason, high pre-heating temperature required, strongly recommend using high temperature switches. cases peak temperature must exceed 260°C, soldering time max. Surface Mount versions methods Infrared, convection vapour phase upper limit 260°C/30 must observed. soldering temperature profile must have moderate temperature gradients T/t. General Temperature limitations temperature 65°C High temperature 160°C LED's 85/100°C Accessories 65°C recommend that accessories mounted after soldering, unless process allows heat exposure kept within limits 65°C. Combinations high temperature switches with LED's will limited temperature capability LED. Packaging UNIMEC MULTIMEC switches packed rigid tubes pieces each.
