Tactile Switch
₹12.00Add to cartA tactile switch, also known as a momentary push-button switch, is a type of electromechanical switch that activates momentarily when pressed, providing tactile feedback. These switches are commonly used in electronic devices for user input, such as keyboards, remote controls, and consumer electronics.
LM7805 IC – 5V Positive Voltage Regulator
₹22.00Add to cartThe LM7805 series of three terminal positive regulators are available in the TO-220 package and with several fixed output voltages, making them useful in a wide range of applications. Each type employs internal current limiting, thermal shut down and safe operating area protection, making it essentially indestructible. If adequate heat sinking is provided, they can deliver over 1A output current. Although designed primarily as fixed voltage regulators, these devices can be used with external components to obtain adjustable voltages and currents.
