Abstract: A pushbutton switch having a contact movable to either of two operating positions. In the alternate action configuration, a leaf spring, acting upon a pivot block, retains the contact in either of its stable positions, permitting the pushbutton to sequentially actuate the switch to one of its operating positions each time it is pushed and released. In the alternative momentary configuration, an additional compression spring returns the switch to the first operating position whenever the pushbutton is released. Either configuration may be constructed as a single pole or as a double pole switch.
