Specialty relays and accessories are specialty or proprietary products and accessories related to relays. There are several types of specialty relays and accessories. Examples include time delay relays, automotive relays, electrical relay, and electronic relays. Time delay relays use solid-state electronic devices to provide a time delay. Time delay relays are used in the power based applications and open and close the contacts at the end of the time delay. Time delay relays can provide a number of timer functions and modes of operations such as delay on make, delay on operate, operate delay, prepurge delay and delay on energization. Automotive relays are used in vehicles. Electrical relays use a solenoid to provide mechanical action. The current flowing through an electrical relay in one circuit can switch on and off a current in a second circuit and moves electrical contacts back and forth. Other specialty relays and accessories are also commonly available.
