In a case where a left-hand push-button switch is ON, a second relay RLis electrically de-energized to open a normally close contact RL-of the second relay RLso that a relay contact circuit RC is opened. If, in this state, a right-hand push-button switch is shifted to a second OFF state, a normally close contact R-of the right-hand push-button switch is opened. Thus, a third relay RLis not electrically de-energized and a first and a second circuits are in cutoff until both the right-hand and the left-hand push-button switches are returned to a first OFF state.

Enabler of teaching pendant

A push-button switchdisposed in a switch casehas c-contacts and a normally close contact electrically connected with a terminal blockvia conductors. Leading endsof cores of a cableintroduced into the switch caseare inserted in insertion holesformed in the terminal block. Screwsmounted to the terminal blockare tightened to press the leading endsof the cores against conductive connection portions, on one side, in the insertion holes, thereby to establish electrical connection.

Grip type switch device and controller for industrial machinery using the switch device

An actuator of the present invention comprises an operation key to be inserted into a key insertion hole formed in the safety switch, and a base The operation key is held on the base and capable of freely swinging in two orthogonal directions. The actuator also comprises means (e.g. a guide stopper and engagement spaces ) for selectively restricting the swinging movement of the operation key to either of the two directions.

Safety switch actuator

A push-button switch and a teaching pendant employing the same are provided. The push-button switch ensures that a push button is capable of switching ON/OFF the switch if one of contacts thereof should fail during an operation of the switch. For achieving this object, a switch case contains two c-contacts each having a snap action configuration and switching mechanisms for opening/closing the c-contacts When a push button is depressed, the switching mechanisms simultaneously open/close the c-contacts for turning ON/OFF a push-button switch
