Relays, solenoids, and contactors are all switches—whether electro-mechanical or solid state—but there are critical differences that make each suitable for different applications. In this article, we will explain how each of these devices work and discuss some key selection considerations.
Any purchasing department is familiar with the term "solid state." Solid state electronics and circuits are fairly common in automotive electrical, but how well do you understand how this technology works, as well as the benefits and drawbacks? So let's take a look at solid state components, and what they mean for vehicles and engineering.
Ever since Waytek added the newest Forward & Reverse Relay Module from Cole Hersee by Littelfuse, we've noticed strong interest from many customers, along with many questions and comments about this new generation of relay modules. Below, we have outlined the features and benefits to help you better understand this new product class.
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.
