Dome Switches in Pune

• Key Travel : 380 microns.
• Current/Voltage Rating : 10 mA at 24 VDC (Max)
• Operating Temperature : -20oC to + 65oC.

These Keyboards comprise of a snap dome switch and a gold plated glass epoxy PCB for base and circuit. Snap Dome Switches (Special SS Alloys) are mounted and sealed on a gold plated PCB to conduct the signals in the keyboard circuit. The switch contacts can be terminated on any type of solderable connector wh more...
