Abstract: A switch device includes an operation knob rotatably supported by a case, and switch mechanisms which can convert a switch circuit (not shown) disposed inside the case by performing a rocking operation on the operation knob. A cam member having a cam face which can deliver click feelings to the operation knob is disposed in the case. The switch circuit is converted in conjunction with the rocking operation of the operation knob, and click feelings are created so as to be delivered to the operation knob.

Abstract: The operation mechanism for electric apparatus is provided. An operation mechanism includes a switch element mounted on a circuit board, an upper housing formed with an opening and covering the circuit board, and an operation grip that has an operation shaft hanging therefrom and which is rotatably supported by the upper housing. When the operation grip is oscillatingly operated, the operation shaft drives actuators of the switch element.

Abstract: Compounds of formula (I): ##STR1## wherein R.sup.1x is hydrogen or methyl, R.sup.2x is hydrogen optionally substituted aliphatic hydrocarbon or acylimidoyl, R.sup.3x is hydrogen or an ester group, and Q.sup.x is cyclic or acyclic nitrogen-containing group. The compounds are potent antibiotics which are resistant to dehydropeptidase I, and are thus useful for the treatment of many microbial infections.
