NKK Switches Offers Process Sealed Miniature Pushbutton Switches
Scottsdale, Ariz. (Nov. 15, 2004) - NKK Switches' continues to lead the electromechanical switch industry with their commitment to provide a full range of switch solutions for today's demanding marketplace.
The M2B series of process sealed miniature pushbuttons switches features an interior o-ring surrounding the actuator within the bushing. The ultrasonic welding of the bushing and housing unit seals out contaminants, which saves them time and money on wave soldering and washing. The bushing and the top of the housing are a single unit construction, giving added protection from cleaning fluids or other liquids. Terminals are epoxy sealed to lock out contaminants such as flux and solvents.
These devices have an anti-jamming feature that delivers long life and high reliable operation. This special feature protects the switch contact mechanism from damage due to excessive actuation force. All bracketed models have crimped legs to insure secure PCB mounting, and to prevent dislodging the switch during the automated processes. The contact mechanism is snap acting which gives the M2B pushbutton switches positive actuation, short travel, light touch, smooth feel and audible feedback. This mechanism also gives the M2B series an electrical life rating of 25,000 operations minimum for silver contacts and 100,000 operations minimum for gold contacts.
Single or double pole, double throw momentary circuits can be specified for the M2B series. Design engineers have a choice of two different plunger lengths and four cap diameters in various colors. These devices are available in straight PC, straight PC with support bracket, right angle and vertical mount terminals. Power rated models are rated 1A @ 125V AC or 1A @ 30V DC. Logic level models are rated 0.4VA maximum @ 28V AC/DC maximum. In addition, gold over silver contacts can be specified to achieve a dual-rated switch.
All models are UL Recognized and CSA Certified. The bushing, housing and base of the M2B series has a flammability rating of UL94V-0.
