Additional Information About Electro-Mech Components Switches
Q: Are EMC parts in stock or built to order?
A: Most parts are built to order. We do maintain stock on a limited supply of standard catalog products and aircraft end-use products. We may have stock on smaller quantities (<10) of SW drawing items. Please Contact Us and we would be happy to check stock on the item you require.
Q: Should I order through a distributor or directly from the factory?
A: Since many parts are custom configurations, our distributors cannot stock all combinations. You can try one of our distributors for the item you require, but most orders are booked directly through the factory. We have a $250.00 minimum factory order on most items.
Q: I cannot locate a data sheet for part number SW4nnnn. Why isn’t it on the web site?
A: The data sheets on the web site are primarily for standard catalog products. There are some SW4nnnn.pdf drawings on the web site. We have assigned thousands of custom drawing numbers in the sequence SW30000 – SW45999 that we cannot possibly include on the web site. Please Contact Us for the data sheet (actual drawing).
Q: The switch I have has a four digit number on it. What is this?
A: EMC prints a date code on all of our switches in the sequence WWYY where WW = week number and YY = year number (e.g. 3213 = 32nd week of 2013).
Q: Is this an EMC part number…?
A: We receive many inquiries referencing “EMC part numbers” which actually are not.
Often, the four digit manufacturing date code is confused for the part number. In general, the marking on an EMC switch is the four digit manufacturing (date) code, 07150 (Federal identification CAGE/FSCM code), Electro-Mech, the part number, and the terminal identification.
Q: I am looking for a transformer made by Electro-Mech. Can you help me?
A: Electro-Mech is a common name used by several other companies:
Products: aircraft motors and blowers

Q: I need to identify an EMC part number for a switch I have in my hand, can you help?
A: Yes, you can contact us directly. We may ask you to send the product to our office for exact identification or please email us a digital photo of the product you have.
In addition, the following information is helpful:
- What series of switch do you think it might be?
- What are the type, shape, and color of the actuator (pushbutton lens)?
- Is there any imprinting on the pushbutton?
- Is the switch illuminated? What are the illumination/lens colors?
- What is the type and number of terminals?
- Does it have Alternate or Momentary action?
- What is the mounting style: snap-in, screw mount, or threaded bezel?
- Who is the manufacturer of the equipment from which the switch came?
Q: Can I purchase a replacement switch directly from you?
A: You can contact the equipment manufacturer for the proper replacement, or we can supply a direct replacement.
If you are unable to obtain a switch or a part number via the manufacturer, then you can contact us directly for help in identifying the switch part number.
Q: Does EMC offer high amperage power switches?
A: EMC Series 4000 is rated 10A resistive, 5A inductive at 30VDC or 125VAC.
Q: My application has special switch requirements which fall outside your standard switch offerings. Can you provide a solution?
A: EMC is a vertically integrated company that can fabricate over 75% of the components that make up its products. This, in combination with complete in-house design, allows us maximum manufacturing flexibility. As a result, we offer a wide range of customized solutions for your specialized switch needs. Our motto: We Make It Special.
Q: What is the electrical life of an EMC illuminated switch bulb?
A: The electrical lives of our switch lamps and LED’s are specified on the individual lamp or LED specification sheets.
Q: What is the operating temperature range of your switches?
A: The temperature range for our pushbutton switches is 0 C to 85 C (32 F – 185 F). For W2100, W2600, and W3900 series switches, operating temperature range per MIL-PRF-22885-F is -55 C to +85 C.
Q: Do you have AutoCAD, DWG, DXF, STP or IGES files of your switches available?
A: Yes. We may have the required file archived in our library, or a drawing may need to be created. Therefore, contact us directly with your request.
Q: What does IP64 mean?
A: IP64 is the International (IEC/EN) rating (Ingress Protection) for degree of protection against ingress of liquid or solid debris. It can also include impact characteristics.
Q: When do you recommend LED illumination in place of incandescent lamp illumination?
A: LED’s (Light Emitting Diodes), composed of a DC diode chip and connections encased in plastic and epoxy which protects against shock and vibration, are considered the ideal illumination choice for the many applications.
At 100,000+ hours, LED lamp life is ten times that of incandescent lamps. Unlike incandescent lamps, heat rise is not a factor for LED life cycle; LED’s generate only a 6 degree temperature rise above ambient, as compared to the 51 degree temperature rise of incandescent lamps. Because LED’s are absent of fragile filaments, they are also not susceptible to breakage or DC notching.
LED’s offer focused beam brightness (measured in millicandellas) which is able to match or exceed the light intensity of incandescent lamps. LED’s are available in a wide range of colors and intensities including the standard 8 millicandella LED, 60-100 millicandella super bright LED, 750 millicandella high intensitry green LED, and the 8000-9300 millicandella megabright amber/red LED. Carling also offers special blue, white and Bluish Green LED’s and Bi-Color and flashing red/amber LED’s.
Typical pricing of LED’s with built in resistors is higher than standard incandescent lamps, but extended life over the life of the installation can save the cost of replacing incandescent lamps.
Q: Do you offer actuator guards for your switches to prevent accidental activation?
A: Our LG Lens Guards will cover any assemblies with the 67- or 674- bezel or part number prefix, and will prevent accidental actuation of the lens. Lens guards come with or without a spring return feature. LGSL = Lens Guard, Spring Loaded.
Q: What is EMC’s Warranty Policy?
A: Electro-Mech Components warrants to all customers that all products sold and shipped to the customer shall be free from defects in material and workmanship for a period of one year minimum. Products with date codes (WWYY) over one year old may be returned at customer’s expense for engineering evaluation of subject products and may be replaced or repaired at no charge should the evaluation determine that EMC is responsible.
In the event of such defects, the seller’s only obligation shall be the replacement of the defective goods. This warranty is the seller’s sole obligation and excludes all other remedies or warranties, express or implied, including warranties of merchantability and fitness for a particular purpose, whether or not purposes or specifications are described herein. EMC further disclaims any responsibility for injury to person or damage to or loss of property or value caused by any product which has been subjected to misuse, negligence, or accident; or misapplied, or modified or repaired by person or persons not authorized by the seller or which have been improperly installed.
