They are fully sealed and suitable for flow soldering and solvent cleaning and numbered types have a black polyamide casing (UL94 rated) and bold white characters. Gold plated wiping contacts ensure reliable low level switching.
Contact Life is extremely long and reliability tests with 16 position switches have demonstrated that after nearly 4,000,000 dry circuit contact closures at 10mVdc/10mA maximum disclosed that more than 99.998% of results had a contact resistance of less than 100m?.
Needless to say, the switches also meet the requirements of EN 60068 and special versions can be manufactured on request.
