Frequently Asked QuestionsBelow are some of our most frequently asked questions. If you have a question that is not on here, then please contact us.
How can I perform an advanced search on this site?
Use the percent symbol % as a wildcard in the searchbox. For example, if you wanted to find all of the PV4 switches that have 12Vblue ring illumination, search for PV4%344. You could also search for switches that have a 100 gram operating force with the term %F100.
How do I know if a switch is washable or sealed?
On the product detail page of every series you will find information about the switch. If it is washable or sealed to a certain IP rating, it will list it on the product detail page. To get to the product detail page, go to our product catalog and search by type or by feature. We have a section of sealed switches here.
How do I know if a cap is available for a switch?
If a specific product uses caps, the cap options are listed on the product detail page on a tab toward the bottom. If you would like to see a list of our full cap options, you can click here.
What is the life expectancy of incandescent bulbs?
They can range from 5,000 to 10,000 hours.
How do I know if a part number is RoHS certified?
It is a safe assumption to note that all our switches comply with RoHS standards. You can find our complete library of RoHS certifications by part number, here.
What is your recommended solder profile?
We have solder profile recommendations for hand soldering, SMT reflow and wave soldering processes. You can find our recommendations here.
What are the different seal ratings and what do they mean?
Water-Wash, Process-Sealed, IP67 Switch Seal Rating
Definition of IP Codes (Ingress Protection):
IEC (International Electrotechnical Commission) 60529 Standards document specifies an international Classification system for the sealing effectiveness of enclosures of electrical equipment against the "Intrusion into the equipment of foreign bodies and moisture".
1. Degrees of Protection - First Digit
2. Degrees of Protection - Second Digit
7 Protection against effects of immersion from 15cm to 1m (6" to 40").
Based on the above, our standard for defining a "process-sealed" switch is "sealed to meet the minimum requirements of IP-67". This means that a switch rated to IP-67 is "Dust-tight" and will pass a water submersion test at 40" (1m), for up to 30 minutes.
Due to the variables encountered in actual water-wash machine processing, IP67 does not necessarily insure that water entry into the switch cannot occur. the water-wash pressures and air-knife drying that occurs in modern pcb machine-washing can exceed the seal requirements of the IP-67 rating.
Are your switches UL certified? CUL? VDE? Can you send me a file number?
E-Switch and Lamb Industries have a variety of certifications. All our certifications can be found on the individual product detail page, with a link to the file numbers. We also have our certifications listed here.
Why can't I run switches with the caps on through my automated solder process?
