Claims

[Scope of utility model registration request]

(1) High-frequency oscillation that includes a detection coil section that has a detection coil embedded in the core, and a circuit section that has an oscillation circuit that includes the detection coil and detects the proximity of an object based on a change in the oscillation state. In the type proximity switch, the detection coil has two electrodes connected to each other at both ends thereof, is connected to a metal film on the outer surface of the core of the detection coil part, and has a relay board having a through hole in one electrode. A proximity switch comprising: two relay wires connecting the relay board and the circuit section.

(2) The proximity switch according to claim 1 of the utility model registration claim, characterized in that an elastic resin is applied to cover the connection points with the relay board at both ends of the detection coil and the connection points between the relay board and the relay wire. .
