Rocker switches have been around since the 1980s, when they were first used in consumer appliances such as dishwashers and washing machines. Today, they’re also popular in a wide range of industrial, commercial and even automotive applications, thanks to their versatility and ease of use. One such rocker switch, the GRS-4021-0004, is designed for use in high-amp applications.

At a glance, the GRS-4021-0004 appears to be a standard, single-pole single-throw (SPST) on/off switch. It has a rocker arm that pivots on a spring-loaded hinge and a bi-colored LED that allows for visual indication of an items’ on/off state. It also has an 8 Amp (2 x 4 Amp) electrical rating.

When it comes to installation, the GRS-4021-0004 is easy to integrate into most environments and requires little cabling. It can be secured using either screws, pliers or screws and nuts. The rocker switch’s small size (just 0.3” wide and 1.4” long) means it can fit into tight spaces, making it ideal for use in commercial, industrial and automotive applications.

The GRS-4021-0004 is not limited to basic on/off switching applications. With its built-in microswitch, the rocker switch can be used as a floating switch, allowing it to act as an “on” switch when pressure is applied to the rocker arm and an “off” switch when pressure is removed. This makes the GRS-4021-0004 ideal for a wide range of pressure-sensitive applications, such as controlling an air compressor, an air filter/regulator or an automatic garage door opener.

In addition to its ability to act as a floating switch, the GRS-4021-0004 also has a snap-in clip, allowing it to be connected to and disconnected from a PCB assembly or other specialized circuit boards. Its rugged and shockproof construction makes it suitable for use in harsh industrial environments, while its flame-retardant plastic housing ensures it is safe to use in enclosed spaces. This versatility makes the GRS-4021-0004 ideal for use in a range of applications, from automotive instrument panel switches to industrial motor control systems.

Lastly, the GRS-4021-0004’s low cost and easy installation make it a popular choice for residential and light commercial applications, such as overhead lighting and home theater systems. The rocker switch’s bi-colored LED ensures the user can easily identify which state the switch is in and make any necessary adjustments quickly and easily.

The GRS-4021-0004 is a versatile rocker switch that is suitable for a wide range of high-amp applications. Its small size, shockproof construction and floating switch feature make it an ideal choice for industrial, commercial, automotive and even residential applications.
