3 a8m a8m precautions to increase the reliability of oper ation, test the switch before actual operation. be sure that there is an enough insulation distance between any switch terminal and metal part. mounting ? turn off the power supply before mounting, removing or wiring the switch, or before performing maintenance inspections. failure to do so many result in electric shock. ? easy to mount by snap fitting. ? do not use panels other than ones with the designated thickness and dimensions. remove all burrs from the cutout before installing the switch. otherwise, the switch may malfunction. ? do not impose excessive force on the switch at the time of panelmounting. otherwise the switch may be damaged or deformed, and the switch mechanism may malfunction as a result. wiring ? when soldering terminals manually, perform soldering within 4 s using a soldering iron (temperature at the tip of the soldering iron: 360 c max). do not apply excessive force to the terminals during soldering. ? quick-connect terminals (#250 t=0.8) are not in compliance with iec standards. suitable for use as solder connection. ? be sure that the wires are thick enough for the load (current) to be applied. ? the performance of the switch may be affected if the switch is used for switching micro loads. test the switch under the actual operating conditions. environment for storage and use ? do not use the switch in places with sulfide gas, corrosive gas, sea breeze, oil spray, or direct sunlight. otherwise, the switch may malfunction. ? do not use the switch in places that are visibly dusty. otherwise, the contacts may fail to operate correctly. ? the switches are not sealed, cannot prevent to enter dust particles and liquid perfectly. test the switch under the actual operating conditions before use. handling ? do not drop the switch. otherwise, the switch may malfunction. ? do not impose excessive force on the switch. otherwise, the switch may deform. ? use the switch within the rated voltage and current ranges, otherwise the switch may have a shortened life expectancy, radiate heat, burn out or malfunction. ? do not impose force to operating part from an angle, otherwise the switch may be damaged or deformed. rohs compliant the ?rohs compliant? designation indicates that the listed models do not contain the six hazardous substances covered by the rohs directive. reference: the following standards are used to determine compliance for the six substances. lead : 1000 ppm max. mercury : 1000 ppm max. cadmium : 100 ppm max. hexavalent chromium : 1000 ppm max. pbb : 1000 ppm max. pbde : 1000 ppm max. caution do not wire the switch or touch any terminal of the switch while power is being supplied. doing so may result in electric shock. pushing position case flange
