Semaphore relay
SPR,SPL TYPE
If the equipment status related to circuits is shown with lamps, e.g., on the electric power system panel, the broken wire in any lamp disables this display making it impossible to indicate the equipment status. Since the semaphore relay uses no lamp, the open/closed status of the equipment is always displayed accurately. The semaphore relay allows for visually checking whether the circuit is connected or not. This assures error-free recognition. The disconnecting switch and circuit-breaker, which show their statuses with the circular and rectangular shapes, are simple and contribute to the improvement of the panel design.
