Precautions
Be sure to read the precautions and information common to all Snap Action and Detection Switches, contained in the Technical User's Guide, "Snap Action Switches, Technical Information" for correct use.
Correct Use
Mounting
The cover has the same electrical potential as the COM terminal. Do not short-circuit the cover with a NO or NC terminal when mounting the cover.
Caution
Electrical Ratings
Confirm the contact load in order to select an appropriate switch rating. Do not apply an excessive electrical load to the contacts, otherwise the contacts may weld, resulting in a short circuit or burning.
Terminal Connection
cover
Do not use flow soldering or hand soldering to solder terminals. Conduct reflow soldering within the range shown in the terminal temperature profile below. Some reflow soldering devices have extremely high peak values. Do a test in advance to confirm proper soldering conditions. Do not conduct reflow soldering more than twice. Also provide a time interval of at least five minutes between the first and second reflow soldering processes to allow the Switch to return to room temperature. Heating the Switch continuously (without an interval) may cause the edges of the Switch to melt and degrade the characteristics. When printing for a cream solder process, a 0.13-mm screen thickness is recommended. Be sure to provide local ventilation.
R1 min
Be careful of the following points. Incorrect handling may lead to insufficient actuator return, Switch damage, or reduced durability. * Set the operating body in line with the direction of the actuator movement, and make sure that the operating body is completely separate from the actuator when the Switch is in the free position (FP). When the actuator is operated from the crosswise direction of the Switch, make sure that the corner of the operating body has a minimum radius of R1.
Operating body
* Set the Switch stroke to 70% to 100% of the overtravel (the difference between the operating position and the total travel position). * Do not subject the Switch to operations that involve strong impact. * Do not use the Switch as a stopper. * Do not apply excessive loads to the cover or operate the actuator from a direction other than a specified operating direction. * Do not use an adhesive to secure the Switch. A lubricant is used in the Switch. Some of the lubricant may seep out because the Switch does not have an airtight construction. Consider this possibility with respect to the usage conditions when designing or using the Switch.
Preheating time: 60 to 120 s Heating time: 40 s max.
Printed Circuit Boards
Special attention must be paid to the handling of printed circuit boards after a Switch has been mounted onto them. Airborne PCB particles may penetrate the interior of the Switch when printed circuit boards are separated by cutting. Also, do not stack printed circuit boards that have Switches mounted on them.
Product Specification Details
This document provides only a partial list of specifications. It is recommended that you request complete drawings and specifications prior to purchasing or using the product.
Application Environment
Do not use the Switch in locations that are subject to toxic gas, silicon, excessive dust, excessive dirt, high temperatures, high humidity, sudden temperature changes, water splashes, or oil splashes. Otherwise, damage resulting by faulty contact of the Switch contacts, corrosion, or other causes, or other functional faults may occur.
RoHS Directive Compliance
Models that are indicated as being RoHS compliant are free of the following six substances. Lead: Mercury: Cadmium: Hexavalent chromium: PBB: PBDE: 1,000 ppm max. 1,000 ppm max. 100 ppm max. 1,000 ppm max. 1,000 ppm max. 1,000 ppm max.
Insulation and Wiring
Be sure that the installation conditions provide a sufficient insulation distance between Switch terminals and other metal parts, lands, etc.
Cleaning
The Switch does not have an airtight construction, and it must not be cleaned with cleaning fluids. Malfunctions may occur if the cleaning fluid penetrates the interior of the Switch together with flux or foreign matter from the surface of the PCB.
Confirmation with Actual Equipment
Be sure to confirm the quality of the product under the load and environmental conditions that will be used during actual applications.
