Rugged and Trouble-Free

Every component of the 304 has been refined and improved over the years to provide dependable operationfor at least 3,000,000 cycles. Its classic simplicity of design makes it virtually trouble-free.

Convenient Adjustment

Graduated in easily read 1% increments, the 304 provides continuous adjustment of on time between 5 and 95%. It also switches the load off continuously when the pointer is set below 3%; and on continuously, when the pointer is set above 98%

Operation

The 304 is comes in 30 second time cycle (60 Hz). Its synchronous motor drives a cam which repeatedly closes the SPST load switch for a percentage of the time cycle, as set on the timer dial, and opens it for the remainder of the cycle. When the dial pointer is set below 3%, the load switch stays open for the full cycle; it remains closed when the pointer is set above 98%.

Series 304 timers operate continuously and do not reset on power interruption; when power is restored, they resume the interrupted cycle.
