Document Type and Number:
Japanese Patent JPH0377223
Kind Code:
A
Abstract:
PURPOSE: To make key operation easy by forming introduction holes in a state that keys can be held without being supported when keys are inserted into the insertion depth as shallow as possible to carry out operation of a first switch module. CONSTITUTION: A key rosette 1 and a first switch module 3 are installed in this switch and further a second switch module 2 which can be operated in relation to the insertion depth of a key 6 is installed. In the module 2, a ball 5 as an operational element is projected into the leading inlet 4 for the key and is composed as a microswitch 2. Consequently, in the depth with which the key 6 does not carry out switching of the switch 2 through the ball 5, the key 6 is prevented from being left as it is inserted due to self retention in a cylinder hole.
