Specialized - Thyratron ·Thyratron
Self-indicating subminiature thyratron for low-power control circuits. Its gas discharge provides switching while visible glow indicates conduction state.
The 7323 is a gas-filled, directly heated subminiature thyratron with negative control-grid characteristics and a visible glow bright enough for direct indication in transistor-era control circuits.
