Do not apply any external force for 1 minute after soldering. Soldering at an excessively high temperature or soldering for more than 3 seconds may deteriorate the characteristics of the Switch. In case of automatic soldering, please do not apply the heat beyond 260°C within 5 seconds. Pay careful attention so that flux or solder liquid does not flow over the edge of the PCB panel. ●Wiring Molded Lead Wire Models •When wiring molded lead wire models, ensure that there is no ●Side-actuated (Cam/Dog) Operation weight applied on the wire or that there are no sharp bends •When using a cam or dog to operate the Switch, factors such near the parts where the wire is drawn out. as the operating speed, operating frequency, push-button Otherwise, damage to the Switch or deterioration in the indentation, and material and shape of the cam or dog will sealing may result. affect the durability of the Switch. Confirm performance specifications under actual operating conditions before using ●Using Micro Loads the Switch in applications. •Even when using micro load models within the operating range shown below, if inrush/surge current occurs, it may increase the contact wear and so decrease durability. Therefore, insert a contact protection circuit where necessary. 10
