<p>A magnetism-sensitive light-emitting proximity switch (10) used for indicating the operating position of a fluid pressure cylinder, a float, etc. An electric circuit (12) including a magnetism sensitive switch (12a) and a light-emitting element (12b) is sealed in a molding body (11) of a light-transmissive resin in place of a resin case. The cost and size of the switch are reduced and waterproofness of the switch is improved. In addition, the light emission range of the switch is widened and the switch can be easily adapted to change the shape.</p> |
