Technical Information
Technical Information
A Pushbutton Switch is a switch designed so that its contacts are opened and closed by depressing and releasing a pushbutton on the Switch in
the direction of its axis. Pushbutton Switches come in two categories: lighted and non-lighted. The structure of a typical Lighted Pushbutton
Switch is shown below. Broadly speaking, Lighted Pushbutton Switches are made up of the 5 sections shown below. Non-lighted Pushbutton
Switches are made up of 4 sections, the 5 sections shown below less the light source.

The pushbutton returns to its original position after it is released.
The first time the pushbutton is pressed, an internal lock mechanism holds it in the same
position. The next time it is pressed, the lock is released and the pushbutton returns to its
original position.
When the pushbutton is pressed, an internal lock mechanism holds it in the same position. The
pushbutton is returned to its original position when the pushbutton is pulled to release the lock.
When the pushbutton is pressed, an internal lock mechanism holds it in the same position. The
