Discover answers to common questions about the materials used in MEC switches. Learn more about our commitment to durability and the high-quality components that make our switches reliable in various environments.
› Do MEC switches and caps resist solvent ink?
The resistance depends on what kind of solvent ink and what type of caps and switches. The plastic material varies between the different switches and caps in our product range and therefore each behave differently towards solvents. Please contact MEC if specific information is needed.
› Do MEC switches and caps resist UV light?
All our switches and caps are resistant to UV light.
› Are Multimec switches dry nitrogen resistant?
The melting point of nitrogen is -210⁰C. If the switches are directly exposed to the nitrogen they will not be able to resist this temperature. The working temperature of the Multimec is min -40⁰C and max +115⁰C for the low temperature version and min. -40⁰C and max +160⁰C for the high temperature version.
› Can the multimec 3F withstand methanol as cleaning solvent after soldering?
The MEC switches are made of quality plastic, however we do not guarantee for the future function of the switch by using organic solvents as a cleaning liquid. We only recommend demineralized water with the same temperature as the switch or slightly higher.
› What is the temperature range of caps?
The polycarbonate caps can be used in ambient temperature of -40/+85⁰C.
- The ABS caps – -40/+65⁰C.
- The PPS caps – -40/+160⁰C.
- Polyamide – -40/+160⁰C.
See more information in the Technical Information area on the MEC product page or in the latest Product Catalogue.
› Do you have specifications about the lifetime of negative printing (number of operations)?
The lifetime of the negative print depends on the external environment in which it is going to operate (where the button is placed, what is it exposed to e.g. heat, dust, moist ect.). Also, it is important how the button is activated: Does the person who presses the button wear gloves; are his fingers dirty, is he using a pen or something to activate the switch? For your information, the print complies with the ISO class: 1/ASTM class: 4b
