Title: Foot switch
Inventor: KOIDE JUNJI
IPC: H01H3/14
Filed: 1988-04-22
Abstract: PURPOSE:To aim at ensuring good operability, prevention of missed operation and reliable operation by checking the operation of a foot switch that is brought into action with voice, prior to its output. CONSTITUTION:A foot switch 1 is composed of a pedal 4 operated with a foot, a push-switch 5 that is turned on by being pressed when the pedal 4 is depressed, a voice synthesizer 6 that comes into action through an output signal from a switch 5, a timer 7 capable of being triggered repeatedly that is brought into action through the output signal from the push-switch 5, and an AND-gate 10 of an open collector output (OC) that derives a logical product from the outputs of the timer 7 and push-switch 5. The data in the PROM 11 are so prepared that activating the foot switch 1 to output a voice 'Open', the timer 7 is so delayed in operation for a certain time after the switch 5 is turned on, that is a time required for allowing repetition of the voice more than once, and then the output of the timer is switched over to 'high'. With this procedure, it is possible to judge by the voice which switch is operated, thereby enabling to prevent, by withdrawing pedal operation based on the judgement, the output from being turned on by mistake.
