GRS-4021B-0003

Rocker switches are electromechanical devices that are frequently used in many applications, ranging from light switches and push button devices to control panels. The GRS-4021B-0003 is one of these devices and is a single pole, single throw (SPST) rocker switch. Its application field and working principle are as follows.

Application Field

The GRS-4021B-0003 is a durable, reliable and economical rocker switch designed to provide reliable switching in a broad range of applications, including industrial and commercial applications. It has an extremely low switching contact resistance of 0.37 ohm, making it ideal for low voltage and low current applications. It is also suitable for switching power to lights, motors and other low power electric appliances. Additionally, it is RoHS-compliant, making it safe for use in electronics.

Working Principle

The GRS-4021B-0003 is a simple rocker switch. It is designed to connect and disconnect two electrical circuits when a rocker is pushed. The switch is actuated when the rocker is pressed to the left, right or center. When the switch is pushed left or right, the switch connects an electrical circuit, and when it is pressed in the center, it disconnects the electrical circuit. When the rocker is released, the switch remains in the same position.

The switch is made up of a stainless steel stem, an actuator and contacts. The stem and actuator are connected by a pin mechanism and are attached to the base of the switch. The contacts consist of two electrical contacts that have a gap between them. When the rocker is pushed, the contacts close, connecting the electrical circuit, and when the rocker is released, the switch opens and stays open.

The contacts of the GRS-4021B-0003 rocker switch are made of copper, silver and other metals, and they are designed to act as a switch many times and still remain reliable and responsive. The switch is designed to work in high humidity environments and perform reliably in a wide range of temperatures.

The GRS-4021B-0003 rocker switch is an extremely reliable and economical device, making it an ideal choice for applications requiring simple switching operations. With its low contact resistance and wide temperature range, it is perfect for low-voltage and low-current operations, and it is RoHS compliant, meaning it is safe for use in electronics.
