AJ4 91 ORDERING INFORMATION TOGGLE SWITCHES WITH HIGH INRUSH RESISTANCE AJ4 (J4) TOGGLE SWITCHES FEATURES 1. Excellent anti-inrush properties allow it to handle large inrush currents. With a wedge mechanism that increases contact efficiency by M2 times and through use of an oxide Ag alloy for superior anti-weld properties, this compact switch is capable of highcapacity switching. This makes it ideal for circuits with high inrush currents such as those in motor load and lamp load. 2. High level of safety with at least 3 mm between contacts. Compliant with overseas safety standards. (ON-OFF and ON-ON type) Insulation distance between recharge part and ground is at least 6 mm and between poles it is at least 3 mm. Compliant with the Electrical Appliance and Material Control Law and EN (Class 1) standard. 3. Structure prevents flux from flowing in. A sealant used around the terminals completely prevents flux from flowing in. 4. Fire retardant molding material used in body. Excels in anti-arcing (180 s) and antitracking (600 V) through use of UL94V-0 fire retardant electric-use molding material. CONSTRUCTION • Wedge mechanism PRECAUTIONS WHEN USING CADMIUM-FREE CONTACT TYPE Models with cadmium-free contacts have been introduced in order to reduce environmentally harmful substances. (“F” is affixed to the end of the part number.) We ask customers who are currently using products with cadmium-containing contacts (no “F” at the end of the part number) to please make the switch to models with cadmium-free contacts. When switching, operating life may differ depending on the load. Please be sure to verify this by conducting an evaluation using actual equipment. 12 dia. RoHS Directive compatibility information http://www.nais-e.com/ Handle with nice feel Oxide Ag alloy contact Superior anti-corrosiveness Superior anti-weld UL94V-0 molded body material Superior antiarcing and fire retardant properties Sealant completely prevents flux from flowing in from around the terminals. Wedge mechanism increases contact efficiency by 2 times so temperature rises are controlled and high capacity switching is made possible.

AJ4 96 NOTES 1. Installation Keep the panel tightening torque to less than 1.96 N·cm. Also, do not tighten the nut, holding the switch. 2. For induction load switching (relays, solenoids and buzzers, etc.) we recommend inserting a suitable spark quenching circuit in order to prevent damage to the contacts due to the possibility of arcing caused by back voltage. 3. For hand soldering, a 350¡C soldering iron should be used with the soldering completed within 5 seconds. Also, care should be taken not to touch the body of the switch with the soldering iron. 4. We cannot guarantee performance if...
