Rocker Switches: the A13KH-CA

Rocker switches are one of the most popular control switches in electronics due to their durability and simplistic design. The A13KH-CA is a double-pole, single-throw (DPST) rocker switch. It is an easily identifiable switch due to its flat, oval shaped actuator with a single rocker arm that controls the switching between two connected circuits.The A13KH-CA rocker switch is an ideal choice for a variety of applications as it can switch a higher current (up to 16A) than smaller switches and is great at resisting vibration and shock. It is often used in a variety of consumer or industrial applications, including controlling lighting, fans, motors, pumps, and power tools.The A13KH-CA can be used to control either AC or DC voltages, though it is important to note that its contacts are only rated for AC operation and are not suitable for DC voltages greater than 24V. It also must be used within a temperature range of -25 to 70 degrees Celcius and within an altitude of 2000 meters.To understand the working principle of the A13KH-CA, it is helpful to think of two physical contacts, one connected to a power source and one to the device being powered. When the rocker switch is in its normal, \'off\' position, these contacts are not touching and no current can flow. When the switch is moved, the actuator\'s arm moves and brings the two contacts together, allowing current to pass through and power the device.The A13KH-CA is considered a \'make before break\' or \'maintained contact\' switch, meaning that power is not completely cut off when the switch is moved between its two positions. When a mechanical force is applied to the rocker switch to move the actuator, it works in the following manner: Firstly the contacts that are connected to the \'off\' position make contact before they disconnect from the \'on\' position, resulting in power being supplied during the transition of the switch. Secondly, once the \'on\' contacts make contact, they keep the connection until the actuator is moved back to the original position.This maintains power to the device until the switch is moved to the opposite position. This is significant due to the importance of safety in many applications, and this feature helps ensure that the device being operated is not unexpectedly cut off from power.The A13KH-CA is easy to install, as it requires just two mounting screws for the switch body and a third for the actuator. Wiring is also simple due to the fact that it uses screw terminals, making it easy to connect wiring from either end of the switch.In conclusion, the A13KH-CA is a reliable and versatile rocker switch that is perfect for a variety of consumer and industrial applications due to its higher current rating and make-before-break contact configuration. Its simple design and easy-to-install wiring make it an ideal choice for anyone looking to control low voltage AC or DC devices.
