Title:
ELECTROMAGNETIC SWITCHING DEVICE
Document Type and Number:
Japanese Patent JP2010108654
Kind Code:
A
Abstract:

To more efficiently suppress occurrence of freezing on a fixed contact and a movable contact to improve contact performance between the contacts under a low temperature.

An electromagnetic switching device includes a body 2, a fixed contact terminal 3, and a case 1 housing the body 2 and the fixed contact terminal 3. The body 2 has an electromagnet 6 having a coil 14 and a movable spring 8 in which the movable contact 20 is arranged on the end thereof. The fixed contact terminal 3 has a fixed contact 21 on one end thereof, and a terminal strip 3a on the other end thereof. The terminal strip 3a is protruded outside the case 1. The movable contact 20 is brought into contact with and is separated from the fixed contact 21 due to the attraction of the electromagnet 6 and the elastic restoring force of the movable spring 8. Further, in a connection part 3b connecting the one end and the other end of the fixed contact terminal 3, a collection part 22 is provided which collects dew condensation generated by a temperature difference inside and outside the case 1.
