    • A multi-stage click switch (21) includes a contact circuit member (25) having switch contact portions (41a, 41b, 42a and 42b) disposed respectively in opposed relation to pressing portions (36a, 36b, 37a and 37b) formed on an operating knob (35) mounted on a housing (32), and a rubber switch member (30) having rubber contact portions (28a, 28b, 29a and 29b) 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.
    • 多级点击开关(21)包括接触电路构件(25),该接触电路构件具有分别设置成与按压部分(36a,36b,37a)相对的开关接触部分(41a,41b,42a和42b) a和37b)形成在安装在壳体(32)上的操作旋钮(35)上,以及橡胶开关构件(30),其具有能够顺序地闭合的橡胶接触部分(28a,28b,29a和29b) 并且根据按压部的移动以多级方式打开开关接触部。 每个橡胶接触部分在操作操作旋钮(35)时通过弹性变形产生由弹性变形产生的弹力的合适的咔哒感。 橡胶接触部分(28a)具有超行程装置,在其导电片(22a,23a)接触到相对的开关接触部分(41a,42a)之后,直到切换操作 橡胶接触部分(28b,29b)完成。
