PURPOSE: To mitigate the shock applied to a push button section and maintain the safety of a switch section by separating the push button section and the switch section, and providing a magnet which turns a contactless switch on at the tip of a plate spring inclined by an operation lift shaft.

CONSTITUTION: When a cap 15 is pushed after a coin is inserted, the peripheral wall of a bowl body 14 is warped, an operation lift shaft 11 is lowered, and a plate spring 12 is inclined to a contactless switch section 2 side. The push point of the shaft 11 is located on the base end side of the spring 12, and the shift quantity of the spring 12 is made larger than the descent quantity of the shaft 11. The inclination angle of the spring 12 becomes the maximum when a flange 15a is brought into contact with a flange 14a, the magnet 12a of the spring 12 is moved near the contactless switch 21 of the switch section 2, and the switch 2 is turned on. The shock applied to a push button section 1 is not transferred to the switch section 2, and the switch section 2 is not damaged. The safety of the switch section 2 is secured, and maintenance can be performed at a low cost.
