Pushbutton switches are a type of switch that is activated by pressing it. The MML21KK3AAKRSDR Pushbutton Switch is an ideal switch for applications requiring light actuation force in low to mid-voltage applications. Its main features include a positive break-before-make contact, quick-make and quick-break without audible click, due to its heavy-duty construction, it can handle up to 20A at 125/250VAC, and it has an IP40 sealing rating.The MML21KK3AAKRSDR Pushbutton Switch is a single-pole double-throw (SPDT) switch, which means that when the switch is actuated it can connect two separate circuits. The switch consists of two parts: a switch body and a plunger mechanism. The switch body contains the contacts, our MML21KK3AAKRSDR contains 2, a Form A and Form B contact. The plunger mechanism, which is actuated by pressing the button, is connected to the switch body by a slidable collar. When the collar slides down the shaft, it opens the Form A contact, then when the collar slides up the shaft, the Form B contact is opened.The working principle of the MML21KK3AAKRSDR Pushbutton Switch is fairly straightforward. When the switch is off, the collars are held in place by the spring, keeping both contacts closed. When the plunger is pressed, the collar moves down die shaft, opening the Form A contact, and when the plunger is released, the collar moves back up the shaft opening the Form B contact. This allows for switching between two circuits automatically, without having to manually open and close each contact.The MML21KK3AAKRSDR Pushbutton Switch is useful in a variety of applications, from consumer electronics to industrial controls. Because of its fast switching speed and low actuation force, it is ideal for applications that require high-speed switching. It is also capable of switching between two circuits simultaneously, making it perfect for applications such as finger-switched circuit selections or regulating motor speed or direction.The MML21KK3AAKRSDR Pushbutton Switch is designed to last for a long time, thanks to its heavy-duty construction and IP40 sealing rating. This ensures that the switch is able to withstand the rigours of frequently switching between two circuits, as well as providing strong surface protection against minor dust and moisture. The MML21KK3AAKRSDR is also RoHS compliant, making it suitable for use in environmentally-sensitive applications.Overall, the MML21KK3AAKRSDR Pushbutton Switch is a reliable, affordable, and easy-to-use switch for applications that require low- to mid-voltage switching. Its fast switching speed, low actuation force, and heavy-duty construction make it an ideal switch for many types of applications. Additionally, thanks to its IP40 sealing rating and RoHS compliance, it is a great switch for applications which require a dust and moisture-proof switch.
