Pushbutton Switches: A165L-JWA-12D-1 application field and working principle

Pushbutton switches are components commonly found in common electrical and electronic circuits. Pushbutton switches can be divided into two categories according to their actions, momentary pushbutton switches and maintained pushbutton switches. Momentary pushbuttons allow for a single, momentary closure of a circuit, which means the circuit will only be activated when the switch is pressed and will be deactivated right after that. Maintained pushbuttons allow the user to switch a circuit on and off by repeated pressing of the button while the action is maintained by a spring return.

A165L-JWA-12D-1 is a momentary pushbutton switch that is a commonly used type of electrical switch in domestic and industrial applications. It is arranged as a four-pole single-throw (SPST) switch. A165L-JWA-12D-1 pushbutton switch works via the electrical contacts inside it; when the switch is pressed, the two contact pieces touch, allowing current to pass through. Once the switch is released, these two contact pieces disjoin, thus disrupting the current to the circuit.

The most common application of A165L-JWA-12D-1 pushbuttons is for doorbells, buzzers, and alarms. In this case, pressing the switch will cause the bell, buzzer, or alarm to sound. Other typical applications of this SPST switch include controlling machinery, activating certain functions of machinery or devices, sending off signals, and triggering information. The operation voltage of the A165L-JWA-12D-1 is DC5V, and its contact resistance is less than 0.1 ohms.

The pushbutton switch is protected by an external rubber seal that makes it water-resistant. The seal protect the contacts from moisture or other substances that could cause malfunction or corrosion of the contacts. Moreover, this switch comes in variety of colors, making it easier to distinguish between different circuits. The colors include black, red, yellow and green.

A165L-JWA-12D-1 pushbutton switch is a reliable and durable electrical switch that can be used in various applications. It is easy to install, and it does not consume a lot of power, making it highly energy efficient. Moreover, the switch is quite affordable and can be found easily in most hardware stores.
