Electromagnetic relay and circuit substrate comprising the same

摘要

An electromagnetic relay and a circuit substrate comprising the same are disclosed, for preventing erroneous operation when they are wet by water, at low cost. The electromagnetic relay comprises a case having fluid-tight characteristics; an excitation coil provided in the case; and electrodes connected to both ends of the excitation coil in a manner such that at least a portion of each electrodes is formed outside the case and is exposed to an area where a liquid can penetrate.
