Rocker switches are a type of electrical switch that is actuated by a rocking actuator (often a rocker) to open or close circuits. The JWS21RAA/UCV type of rocker switch is a versatile switch used in a wide variety of applications, from controlling electrical currents for industrial applications to controlling power and indicators for consumer electronics.

The JWS21RAA/UCV switch is a single-pole, double-throw (SPDT) rocker switch featuring a strong, brass-jacketed plastic frame that is fastened to a printed circuit board. The SPDT switch is designed to provide break-before-make switching between two loads when actuated. This switching arrangement is advantageous when both loads must be isolated when being operated or disconnected in order to ensure safe operation. The incorporated actuator is designed to provide a smooth, tactile "click" when actuated, great for equipment requiring this feature such as those used in industrial and medical applications.

The JWS21RAA/UCV is a series of long-life, surface-mount rocker switches that feature a low profile and a wide range of actuation forces from 0.5N to 1.25N. This range of switching current, from 0.1mA to 10A, makes them ideal for a variety of industrial and consumer applications. The rated contact resistance, at 200m? maximum, ensures reliable connections between the switch and the circuit board. Additionally, gold-plated contacts provide improved conductivity, great for high-frequency audio applications.

Generally, JWS21RAA/UCV switches are intended for single-throw (SPST) applications and feature two contacts: a switch common and a normally-open (NO) terminal. This arrangement is ideal for momentary switching such as those used in test equipment, medical equipment, audio and video equipment, and many other electrical control applications. Their small size makes them perfect for any space-constrained application.

The JWS21RAA/UCV switches are widely used for single-throw applications for momentary pulse switching and for providing isolation between two circuits when the switch is powered off. In either application, it features a design that allows for smooth and positive tactile feedback when actuated, as well as a current rating selection. With a wide selection of current and voltage ratings, the JWS21RAA/UCV can provide reliable switching and isolation in countless applications.
