The upper and lower operation panels 32 and 18 are provided with self-holding crusher switches 23 'and 23, which are called "alternate switches", in which one side contact and the other side contact can be switched on and off by push-in / pull-out operations, respectively. Each of the crusher switches 23 'and 23 has a contact 41' on one side and a connection C on a line 41, a contact D 'on the other side and a contact 42 on a line 42, and a crusher controlling electromagnetic switching valve. A power supply circuit 43 for applying a voltage to a solenoid (not shown) of 36 and a crusher switch 23 of the two crusher switches 23 'and 23, for example, are communicated via a solenoid of the electromagnetic switching valve 36. And crusher switch 23 '
When the electric path between the two crusher switches 23 'and 23' is energized or de-energized, one of the two crusher switches 23 'and 23 is grounded via the operation position contact b of the operation changeover switch 20. By operating the switch, the electric circuit is de-energized or energized.

The upper operation panel 32 and the lower operation panel 18

Flows through the working position contact b to ground. Thus, the crusher 16 is activated and the lamps 29 'and 2
9 turns on. When one of the crusher switches 23 'and 23 is in the push-in operation state and the other is in the withdrawal operation state, the crusher switch 23'-2
The circuit between the three is cut off. Therefore, in this case, the crusher 16 is stopped and the ramps 29 'and 29
Is off. That is, the operator looks at the lamps of one of the upper operation panel 32 and the lower operation panel 18 to check whether a predetermined actuator, for example, the crusher 16 is in an operating state or a stopped state. Can be.

In the above case, for example, both lamps 2
To stop the crusher 16 whose 9 ', 29 is lit, one of the upper and lower crusher switches 23', 23 is operated (if the operated crusher switch is in the depressed state). The crusher 16 can be stopped by performing a pull-out operation, and conversely, performing a push-in operation if it is in a drawn-out state). Conversely, as shown in FIG. 6, when the electric paths 41 and 42 between the crusher switches 23 'and 23 are in a non-energized state (therefore, both lamps 29' and 29 are turned off), the crusher switch 23 'is pushed in, or When the crusher switch 23 is pulled out, the electric circuit 41 or 42 is brought into a communication state, and the crusher 1
6 can be activated.
