Push Buttons
Push button switches are widely recognized and utilized devices that can be found in various applications around the world. When someone refers to a push button, they're typically talking about a simple switch mechanism that allows a user to control a function or action within a device or system. There are different types of pushbutton switches, such as momentary switches, which only remain actuated as long as the user is pressing them. Once released, these momentary switches revert to their original position. On the other hand, maintained push button switches stay in their actuated position even after the user has stopped pressing them, much like an "on-off" function.
In terms of electrical functionality, push button switches can be classified by the number of terminals and circuits they can control. For example, SPST (Single Pole Single Throw) is a type of push button switch that controls a single circuit. In contrast, SPDT (Single Pole Double Throw) can control two separate circuits but only has one actuated or "on" position. DPDT (Double Pole Double Throw) can control two circuits and has two actuated positions.
