Operation ■ Precautions for Correct Use • Do not repeatedly operate the Switch with excessive force. soldering Applying excessive pressure or applying additional force after Do not exceed the following terminal temperature profile during the plunger has stopped may deform the disk spring of the soldering in a reflow oven. Switch, resulting in malfunction. • Be sure to set up the Switch so that the plunger will operate in a straight vertical line. 260°C If the plunger is pressed of-center or from an angle it may cause 220°C deformation or damage to some parts. 180°C • We recommend using a round bar with a diameter of at least 3 mm as the actuator. 150°C Main heating Preheating time time 60s max. 60 to 120s Time Dust Countermeasures Washing Do not mount or use the Switch in areas that are subject to dust. The Switches are not sealed, and cannot be washed. If dust is unavoidable, protect the Switch with a sheet or other Doing so will cause the washing agent, together with flux or dust countermeasure. particles on the PCB, to enter the Switch, resulting in malfunction. Water and Drip Resistance Packaging Specifications The switch is not water or drip resistant.
