PROBLEM TO BE SOLVED: To provide a rotary push switch with durability lifetime enhanced. SOLUTION: The rotary push switch includes a push button 12 fitted between an upper part housing 10 and a lower housing 11, an actuator 13, a shaft 14, a spring 15, an operation terminal 16 and a fixing terminal 17. By a pushing action of the push button, the shaft and the operation terminal are intermittently rotated in contact with the fixing terminal with an action of the actuator so as to operate on/off. The operation terminal is structured of a body part supported by a lower end of the shaft and a plurality of terminal parts retaining a constant interval as being extended in a circumference direction from the body part. The terminal part is in a band shape being bent with a contact angle at a lower part, and rotated with the use of tension while contacting with a fixing terminal side. COPYRIGHT: (C)2010,JPO&INPIT |
