PUSH BUTTON SWITCH, AND TEACHING PENDANT THEREWITH

摘要

PROBLEM TO BE SOLVED: To provide a push button switch capable of reliably performing ON- OFF operation of the push button switch even when one contact is failed while using the push button switch, and a teaching pendant using the same. SOLUTION: Two c-contacts 9a and 9b having a snap action are provided in a switch case 3, and switching mechanisms 11a and 11b for opening/closing the c-contacts 9a and 9b are provided. When a push button 5 is pushed in, the c-contacts 9a and 9b are simultaneously opened/closed by the switching mechanisms 11a and 11b to turn ON/turn OFF the push button switch 1.
