FLEX-14 14mm Reed Switch
RoHS
Description
The FLEX-14 reed switch is a sub-miniature, normally open switch with a
14.00mm long x 2.28mm diameter (0.551” x 0.090”) glass envelope, flexible,
easily formed leads, capable of switching 200Vdc at 10W. It has high insulation
resistance of 1010 ohms minimum and low contact resistance of less than
100 milliohms.
Features
• Sub-miniature, normally
open switch
• Longer leads are flexible for
easy forming

Notes:
1. Contact rating - Product of the switching voltage and current should never exceed the wattage rating. Contact Littelfuse for additional load/life information.
2. When switching inductive and/or capacitive loads, the effects of transient voltages and/or currents should be considered. Refer to Application Notes AN108A and AN107 for details.
3. Electrical Load Life Expectancy - Contact Littelfuse with voltage, current values along with type of load.
4. Breakdown Voltage - per MIL-STD-202, Method 301.
5. Storage Temperature - Long time exposure at elevated temperature may degrade solderability of the leads.
