Timing Alternating & Sequencing Relays.
Timing, Alternating, & Sequencing Relays can be utilized for control of electrical circuits based on specific timing and pattern functions. These relays can open or close their contacts based on time-delay settings, alternating patterns, or designated sequences. We carry a wide variety of timers with an even wider variety of timing functions. Each timer is ideal for different types of applications depending on timing functions, electrical specifications, and form factor.
