<p>PURPOSE:To make the operability for left-hander not inferior to the operability for right-hander by providing a change-over switch in the middle of a push button series and an output terminal series so as to change over transmitted signals. CONSTITUTION:A change-over switch 5 is provided between push buttons 1-4 and output terminals 6-9. When the change-over switch 5 is situated in the right hand side, the output due to the push-down of the push buttons 1-4 is output from the terminals 6-9 respectively. When the change-over switch 5 is situated in the left hand side, the output due to the push-down of the push buttons 1-4 is output from the terminals 9-6 respectively. As the push button is provided in the order of using frequency, with the same operability as that for a right-hander when he/she operates the push button 1 with his/her right pointing finger, a left-hander can operate the push button 4 with his/her left pointing finger, so as to transmit the same signal.</p> |
