Correct Use Mounting * Always make sure that the power is turned OFF before mounting, removing, or wiring the Switch, or performing maintenance. * Do not tighten the mounting ring more than necessary using tools such as pointed-nose pliers. Doing so will damage the mounting ring. The tightening torque is 0.98 to 1.96N*m. * Recommended panel thickness: 1 to 5 mm. Wiring * Terminal screws must be Phillips with a square washer. * The tightening torque is 1.08 to 1.27N*m. * Single wires, stranded wires and crimp terminals except round type can be connected to the Switch. * Applicable Wire Size Strand wire: 2mm2 Maximum Solid wire: 1.6mm diameter Maximum Bare Crimp Terminals Operational Environment * The IP65 model is designed with a degree of protection so that it will not sustain damage if it is subject to water from any direction to front of the panel. * This Switch is indoor use only. Outdoor use of the Switch will cause operation failure of the Switch. * Do not use the Switch in the water, oil, or in locations where water, oils, detergent, chemicals, or solvent is applied to the Switch always. Otherwise, switching failure will be happened. * Do not use the Switch under the environmental condition where corrosive gas (ammonia, chlorine, dioxide sulfur...etc.) is generated. Otherwise, the Switch will corrode. * Do not use the Switch in locations where dust, metal or plastic dust exists. Dust will accumulate o the Switch, and then the Switch wouldn't operate normally. * Do not use the Switch under the environmental condition where excessive vibration or shock exists. Otherwise, incorrect switching would occur. Electrical Conditions * The switching load capacity of the Switch greatly varies between AC and DC. Always be sure to apply the rated load. The control capacity will drastically drop if it is a DC load. This is because a DC load has no current zero-cross point, unlike an AC load. Therefore, if an arc is generated, it may continue for a comparatively long time. Furthermore, the current direction is always the same, which results in a contact relocation phenomena whereby the contacts easily stick to each other and do not separate when the surfaces of the contacts are uneven. * Some types of load have a great difference between normal current and inrush current. Make sure that the inrush current is within the permissible value. The greater the inrush current in the closed circuit is, the greater the contact abrasion or shift will be. Consequently, contact weld, contact separation failures, or insulation failures may result. Furthermore, the Switch may be broken or damaged. * If the load is inductive, counter-electromotive voltage will be generated. The higher the voltage is, the higher the generated energy will be, which increase the abrasion of the contacts and contact relocation phenomena. Be sure to use the Switch within the rated conditions. I (A) 8mm max.

Using the Switch for opening and closing a microload circuit may cause contact failure. Use the Switch within the operating range as shown in below chart. Voltage (V) * Secure appropriate insulation distance after wiring of the Switch. * Perform wiring so that the lead wires will not be caught on other objects as this will cause stress on the Switch terminals. Wire the Switch so that there is slack in the lead wires and fix lead wires at intermediate points. If the panel to which the Switch is mounted needs to be opened and closed for maintenance purpose, perform wiring so that the opening and closing of the panel will not interfere with the wiring. 0.16mA 1.6mA 100mA 30 24 Microload area Standard load area 12 Invalid area 5 0 0.1 1mA 10mA 1 10 Mechanical Conditions * Do not use the Switch for loads that exceed the rated switching capacity or other contact ratings. Doing so may result in contact weld, separation failure, or insulation failures. Furthermore, the Switch may be broken or damaged. * Do not touch the charged switch terminals while power is supplied, otherwise an electric shock may be received. * The life of the Switch varies greatly with switching conditions. Before using the Switch, be sure to test the Switch under actual conditions. Make sure that the number of switching operations is within the permissible range. If a deteriorated Switch is used continuously, insulation failures, contact weld, contact failures, switch damage, or switch burnout may result. * Do not apply excessive or incorrect voltages to the Switch or incorrectly wire the terminals. Otherwise, the Switch may not function properly and have an adverse effect on external circuitry. Furthermore, the Switch itself may become damaged or burnt. * Do not use the Switch in locations where flammable or explosive gasses are present. Otherwise switching arcs or heat radiation may cause a fire or explosion. * Do not drop or disassemble the Switch, otherwise it may not be capable of full performance. Furthermore, it may be broken or burnt. * Operating the Switch using a hard object (e.g., metal), or with a large or sudden force, may deform or damage the Switch, resulting in faulty or rough operation, or shortening of the Switch life. 100 1,000 Current (mA) * When use the Switch for opening and closing a microload or large-load, use the Switch with an appropriate relay. Hammer Do not apply excessive or sudden force. * The pushbutton surface is composed of resin. Therefore, do not attempt to operate the pushbutton using a sharp object, such as a screwdriver or a pair of tweezers. Also, do not drop, throw, or knock the Switch. Doing so may damage or deform the pushbutton surface and result in faulty operation. Do not use sharp objects. LED * The LED current-limiting resistor is built-in, so internal resistance is not required. * If commercially available LEDs are used, select the ones that meet the following conditions: Base: BA9S/13@ Overall length: 26mm Maximum Power consumption: 2.6 W Maximum Storage Motor (Approximately 5 to 10 times higher) (Current) Switching * When the Switch is left unused or stored for long periods, the ambient conditions can have a great effect on the condition of the Switch. In certain environments, leaving the Switch exposed may result I deterioration (i.e., oxidation, or the creation of an oxide film) of the contacts and terminals, causing the contact resistance to increase, and making it difficult to solder the lead wires. Therefore, store in a well-ventilated room, inside, for example, a non-hygroscopic case, in a location where no corrosive gasses are present. * If the Switch is stored in a location where it will be exposed to direct light, colored resin in the colored plate may fade. Therefore, do not store the Switch I locations where it will be exposed to direct light. Screwdriver Tweezers * Periodic maintenance is required to use the Switch stably.
