SPST Relays

Single Pole Single Throw relays provide the most straightforward approach to isolation. A single stationary contact and a movable contact furnish a simple on-off configuration.  Forms include normally open, NO, and normally closed, NC. Normally open relays provide voltage isolation until coil power is applied. With coil power applied there is continuity through the relay contacts. Normally closed relays provide continuity through closed contacts until coil power is applied where the relay contacts open providing isolation.  GLVAC offers several design styles including High Voltage and RF reed relays along with traditional ceramic vacuum and gas filled High Voltage Relays.  Each of these relay design types offer unique advantages depending on the application.
