Specialized - Thyratron ·Thyratron
Mercury-vapor relay/control tube in which the grid triggers anode conduction; grid control returns only after the anode current is interrupted.
Mercury-vapour relay in which the grid controls the onset of anode current; after triggering, grid control returns only after anode current is interrupted.
European 5-pin base
