Contactors have long been a go-to switching solution for vehicles with multiple batteries or auxiliary equipment drawing substantial electrical loads. As transportation and work vehicles grow more complex and EV applications increase in prevalence, contactors are evolving to meet higher voltage requirements.
Police vehicles continue to evolve, utilizing a growing array of electrical equipment ranging from sirens, flashers, and spotlights to radio systems, computers, safety locking mechanisms, and more.
Police cars require more auxiliary electrical power, circuitry and wiring than typical passenger vehicles. To support the demand, police vehicles come with powerful alternators (delivering 225 amps or more) and heavy-duty auxiliary batteries.

Time delay relays are designed to control an event based on time. Work trucks, buses, emergency vehicles and other mobile equipment require delayed circuit operation for several applications. The solid state design of time delay relays withstands the electrical environments typically found in on and off-road vehicles and equipment. The key is selecting the right time delay relay for your application.
