ABSTRACT:
The leaf switch of the invention consists of an optical switch mounted on a printed circuit board having electrical conducting means imbedded therein. An opto-interrupter is mounted on an actuator arm that is moved by the player controlled button to close the optical switch and complete the electrical circuit. To complete more than one circuit, a plurality of optical switches are provided with the opto-interrupter mounted on the actuator arm associated with each optical switch. The opto-interrupter is configured such that different ones of the switches are closed depending on how far the player controlled button is depressed.
