Electromechanical

ATC mechanical timers are noted for their circuit flexibility. The 305E provides the highest accuracy among analog timers. Available for either ON-Delay or OFF-Delay operation. The 305E provides delay, interval or pulse timing function for up to 7 load circuits through two instantaneous and two delayed switches. It features a plug-in design and cycle progress indication. The ATC 322B, for example, is a dial-adjustable TDR with cycle progress indication, which can also be used as a low-cost automatic reset timer for a wide range of interval, delay and pulse timing functions, in either ON-delay or OFF-delay operation.
