ABSTRACT:
A multi-stage click switch (21) includes a contact circuit member (25) having switch contact portions (41a, 41b, 42aand42b) disposed respectively in opposed relation to pressing portions (36a, 36b, 37aand37b) formed on an operating knob (35) mounted on a housing (32), and a rubber switch member (30) having rubber contact portions (28a, 28b, 29aand29b) which can sequentially close and open the switch contact portions in a multi-stage manner in accordance with the movement of the pressing portions. Each of the rubber contact portions produces a suitable click feeling by a resilient force, produced by elastic deformation of the rubber contact portion, at the time of operating the operating knob (35). The rubber contact portion (28a) has overstroke means by which after its conductive piece (22a, 23a) contacts the opposing switch contact portion (41a, 42a), a click feeling is not produced until the switching operation of the rubber contact portion (28b, 29b) is completed.
