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.

Specialty relays and accessories are available with a variety of specifications. For example the user interface specifications associated with time delay relays include input controls and displays. Input controls on this specialty relay include none, analog, or digital signals. Display types include none, analog meters or simple visual indicators, and digital numerical displays. The output specifications that need to be considered for time delay relays include the switch type, number of contacts, contact configuration, and pole and throw specifications. Electronic relays are available in AC and DC versions and can provide innovative, reliable, and wear-free switching and can exist up to 230V output voltage and 3.5A output current. Automotive relays can be of two types, PCB and plug in type relays and can handle up to 100 A. Automotive relays come with coil ratings of 6, 12, or 24 Vdc. Other specifications associated with automotive relays include contact form, maximum operating current, maximum operating voltage, maximum operating power, coil rated voltage, and terminal type. Pressure connection, pressure adjustment range, and maximum pressure should be considered when utilizing electrical relay equipment. Before using electronic relays, adequate shielding must be ensured so that the relays will be protected against the radiation generated by small handheld radio transceivers. Specialty relays and accessories can be designed and manufactured to meet most industry specifications.

Specialty relays and accessories have a wide range of applications. Time delay relays can be used in applications that needs time adjustments. Time delay relays can provide a complete timing solution, simplicity, and ease of use. Automotive relays are used in the automotive industry for applications such as comfort controls, power windows, and central door locking. An electrical relay can be used in burglar alarms. Electrical relays can be used for starting fan induction terminals, controlling one, two, or three stages of electric heat, or one, two or three stages of refrigeration. Electronic relays are used were high switching resistance and reduced maintenance are required. All electronic relays must meet ANSI/IEEE standards C37.90.1 and C37.90.2 in order to evaluate their susceptibility to electrical surges and electromagnetic radiation. Specialty relays and accessories play a vital role in many engineering applications.
