Otherwise faulty contact may result the sealing rubber. due to the generation of silicon oxide. •When handling the Switch, ensure that pressure is not applied to the posts in the directions shown in the following diagram. (cid:79)Soldering Also, ensure that uneven pressure or pressure in a direction When soldering the lead wire to the terminal, first insert the other than the operating direction is not applied to the Actuator lead wire conductor through the terminal hole and then as shown in the following diagram. Otherwise, the post, conduct soldering.

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.

Confirm performance specifications under actual operating conditions before using (cid:79)Using Micro Loads the Switch in applications. •Even when using micro load models within the operating range, if inrush/surge current occurs, it may increase the contact wear and so decrease durability. Therefore, insert a contact protection circuit where necessary. 10
