Abstract
A locked-type push button device has a plurality of push buttons and permits only any one of the push buttons to be locked in the depressed state when depressed. Each push button has a leaf spring for returning the push button to the initial non-depressing position, and has a cam engaging portion which can be engaged with a cam member when depressed. The cam member has a spring member to urge the cam member against the cam engaging portions. When more than two push-buttons are depressed, the total force of the two leaf springs of the two push buttons prevents the cam member from holding the cam engaging portions of two push buttons depressed.
