Abstract
A push button switch is disclosed comprising first and second spring returned push buttons movable in a resinous plastic casing along parallel paths, switching contacts in the casing and operable by the first push button, a flexible resilient latching spring arm molded in one piece with the casing and extending between the push buttons, cooperative latching elements on the first push button and the latching spring arm for causing deflection of the spring arm followed by latching of the first push button in its depressed position, and cooperative unlatching elements on the second push button and the spring arm for deflecting the arm and thereby causing disengagement of the latching elements in response to depression of the second push button. A third push button may also be provided to operate momentary switching contacts in the casing, with interengaging elements on the third and first push buttons for causing depression and latching of the first push button when the third push button is depressed and released.
