Abstract
A position detection switch is provided with a case having a cylindrical part that has a plurality of ribs on an inner circumferential wall thereof along the axial direction thereof. Accordingly, the strength of the case is increased and running of a molten resin for fixing a substrate disposed on the inside are improved when the molten resin is injected from a long groove of the case. The contact surface area between the ribs and a sheath is increased whereby durability against an external force and temperature variation is increased.
Claims9
A position detection switch, comprising:
- a sensor case;
- a circuit substrate with an electronic component mounted thereon to be disposed inside the sensor case;
- and
- a cable including a lead wire electrically connected to the circuit substrate, wherein:
- the lead wire is enclosed with a sheath;
- the sensor case includes a plurality of ribs separate from each other at a predetermined interval on an inner wall of the sensor case and extending in an axial direction of the sensor case;
- and
- the ribs separate the sheath from the inner wall of the sensor case to leave a gap between the sensor case and the sheath in injection of a molten resin into the sensor case.
