However, if the lever is too long, improper switch resetting or contact chattering may occur. Therefore, the shape of lever as shown below is suitable. In addition to the standard wire lever model shown here, various other levers are available upon request. 1.6 Mounting Actuator Lever 0.6 dia. stainless steel wire 3.6 1. Insert the end of the actuator lever into the hole in the rotary disc. Center of rotating axis l The appropriate value of dimension (l) from the fulcrum is 50 mm. 2. Push the lever down in the direction of the groove in the rotary disc. Precautions Mounting/Soldering Use M3 mounting screws with plain washers or spring washers to mount the switch. Tighten the screws to a torque of 3 kg S cm (0.29 N S m). When soldering a lead wire to a terminal of the D2MC, use a soldering iron with a maximum capacity of 60 W and do not take more than 5 s to solder the lead wire, otherwise the characteristics of the D2MC may be altered. Applying a soldering iron for too long a time or using one that is rated at more than 60 W may degrade the switch characteristics. Do not change the operating position by modifying the actuator.
