( A technically superior alternative to conventional switching systems ) |
A Snap dome switch is a momentary spst type contact switch with PTH PCB (hard back) & POLYCORBANATE overlay. The switch signals are routed in & out via any kind of PCB mountable connector like FRC, RELIMATE etc. or as specified. The two common forms of circuit designs are XY matrices or common bus or as per specifications. Snap dome switches offers infinite design flexibility in construction & improved reliability, as 90% fewer seperate parts than conventional switch upto 75% reduction, result slimmer end production. |
