What is a switch? A switch is a very simple electronics
component. At the most basic level, a switch just connects and
disconnects parts of a electric circuit. VEX currently
manufactures two types of switches, the limit switch and the
bump switch. Although they look very different, their function
is exactly the same. Both can be classified as Single Pole,
Single Throw (SPST) switches, which will either have the
terminals connected or disconnected based on the state of the
switch. Additionally, the switches are momentary push buttons,
which means that they will naturally be open (disconnected)
until they are pressed, which closes the switch and connects the
terminals. As soon as the switch is no longer being pressed it
will return to being open.
