Abstract:
A rotary push switch obtained by assembling upper and lower housings, in which a push button, an actuator, a return spring, and a movable terminal are inserted into a carrier within the upper housing via an assembling hole formed through the upper housing so that the push motion of the push button is changed by the actuator into intermittent rotary motions of the carrier and the movable terminal, and a plurality of fixed terminals are assembled in the lower housing so that ON and OFF positions of a contact between the fixed terminals and the movable terminal are alternated by the rotation of the movable terminal,wherein: each of the plural fixed terminals includes a connection portion having upper and lower elastic sections, which are curved, and a filling hole serving to allow a liquefied resin to be fed therethrough so as to form the lower housing integrally with the fixed terminals; the carrier includes a prominence formed along an upper part of an outer circumference spaced from a flange formed along a lower part of the outer circumference, and an elastic groove formed through the upper part in a designated depth for allowing the upper part of the carrier to be elastic so that the return spring and the actuator inserted into the carrier are firmly fixed to the prominence so as to prevent the return spring and the actuator from separating from the carrier, and then the push button is assembled into the upper part of the carrier and the moveable terminal is assembled into the lower part of the carrier; and a plurality of locking grooves are formed along the external surface of one housing of the upper and lower housings, and a plurality of locking protuberances corresponding to the locking grooves are formed along the external surface of the other housing of the upper and lower housings so that the upper and lower housings are combined with each other by elastically inserting the locking protuberances into the locking grooves.
