Pushbutton Switches
Pushbutton switches, called push switches, are electronic switches that control electric flow within circuits, electronic devices, appliances, and control panels by manually pressing an integrated and easy-to-press button. The primary purpose of a pushbutton switch is to either initiate or interrupt the electrical connection. Based on actuation mechanisms, pushbutton switches return to their original state upon pressing the button, called normally open pushbutton switches. On the other hand, normally closed pushbutton switches retain their position (electrically connected) and break the connection when the opposite action is performed. Pushbutton switches find applications in diverse fields where manual control is required.
Why Buy Pushbutton Switches?
Pushbutton switches are worth buying products due to their specific features and functions. These switches offer numerous advantages to users, such as compact sizes, versatility, safety, durability, cost-effectiveness, customisation, aesthetics, haptic feedback, easy installation, and convenient integration.
Two Popular Types of Pushbutton Switches:
Among the most popular pushbutton switch types, momentary and latching pushbutton switches are widely used.
- Momentary Pushbutton Switches – These switches remain active as long as they are pressed and return to their default state when released, breaking the electrical connection. Momentary pushbutton switches are preferred for applications like turning on lights, starting machines, or initiating short-term actions.
- Latching Pushbutton Switches – Latching switches have two stable states and physically change the switch's state by button pressing, remaining intact until it is pressed again. These switches are commonly used to power on/off machines or devices required to stay in the chosen state until explicitly changed.
SPST, DPST, SPDT, and DPT Pushbutton Switches
SPST, DPST, SPDT, and DPDT pushbutton switches are common push-switch types used in electrical and electronic circuits. They determine how the switch contacts are configured and behave when the button is pressed or released. These pushbutton switches provide versatile options for controlling circuits with different requirements for connectivity and switching. The choice of switch type depends on the specific needs of the circuit or design system.
