An electronic component device includes an electronic component element 13 that is interposed between a pair of spring terminals 14 and 15. The electronic component element 13 is resiliently held by the spring terminals 14 and 15, and contact portions 17 and 18 of the spring terminals 14 and 15, which are respectively brought into contact with electrodes 13b and 13c of the electronic component element 13, are positioned on both major surfaces of the electronic component element 13 so as not to be opposed to each other. At least one groove of a set of grooves 16a to 16c is formed on at least one of the major surfaces of the electronic component element 13 for guiding the direction in which the electronic component element 13 is divided when the electronic component element 13 is destroyed by, for example, an abnormal voltage.

PTC circuit protection device with non-opposed spring terminals

A circuit for starting a single-phase AC induction motor 11 having a main winding 12 and an auxiliary winding 13, which is so constructed that a PTC element 16 and a triac 17 are connected in series with the auxiliary winding 13 and a gate voltage of the triac 17 is reduced to turn a portion between main terminals of the triac 17 off after a predetermined time period has elapsed since the motor 11 was started, and can effectively lower the power consumption without degrading starting characteristics and can shorten return time required until the motor 11 is restarted and lengthen the life of the PTC element 16.
