In some pushbutton switches, you push the switch once to open the contacts and then push again to close the contacts. In other words, each time you push the switch, the contacts alternate between opened and closed. These types are commonly called latching switches. There are also Non latching push button switches that only maintain the switch contacts when the switch is help in position. Once the switch is let go, the current is broken and the switch turns off. Push switches are usually a simple on-off switch.
